Editorial Welcome to the August issue of World Pumps Our features this month begin with a look at the use of pumps as turbines in the water industry. Running centrifugal pumps in reverse rotation mode has been exploited to a limited degree as a means of generating power in locations where it is considered too expensive to purchase a hydro turbine. Nowadays, running pumps as turbines (PaTs) has become seen by some operators of small hydropower plants and pump manufacturers as an efficient method of generating power as well as recovering energy and contributing to savings. There is the added benefit that pumps are less complicated to operate than turbines. ‘Improving open canned systems’ discusses how the results of a study on the hydraulic performance of open-bottom canned pump intakes can aid engineers and pump users to design these systems with reduced velocity fluctuations and undesirable flow rotation. Design improvements are also at the core of the next article ‘Blade adjustment cuts energy costs’. Once again, it shows that detailed design improvements can pay great dividends when it comes to energy savings. This article explains how power plants can save energy by using cooling water pumps with an adjustable pitch angle of propeller to change the flow rate. However, good design is one thing, but keeping what you have going is a full time job for many pump engineers. ‘Keeping track of bearing wear’ argues that effective monitoring of thrust bearing wear is a crucial factor in preventing pump and impeller damage. This article describes the techniques available for monitoring thrust bearings on boiler feed equipment and explains how the technology can be successfully implemented and commissioned. Finally, in ‘Applying NPSH to metering pumps’, we look at how net positive suction head calculations are routinely used to establish whether centrifugal pumps will operate satisfactorily in a given process.

Muncher meets process requirements

Pressure boosting helps fire-fighting

Mono NOV has added to its TR Muncher range. The new model has been especially designed to protect downstream equipment from blockages, meeting discharge requirements in sludge/fat processing. “Downstream process requirements have changed due to the increasing installation of finer inlet screens, resulting in reduced particles and solids loading within the sludge treatment process,” said Ian Hallows, business manager for Waste-Tec products at Mono.

KSB has launched two automatic package pressure boosting units for fire-fighting systems.

The Muncher features a trash trap, inclined cutter stack and pull-back design. The cutters can be specified to either 8.0 mm,

The Hya-Solo D FL single-pump unit and the Hya-Duo D FL dual-pump units have been designed for use in residential buildings as well as on commercial and industrial premises. Their maximum flow rate is 110 m3 per hour, to a head of up to 160 m.

The addition to Mono NOV’s Muncher range.

5.5 mm and 3.0 mm thickness to match particle size. www.mono-pumps.com

The Hya-Duo D FL dual-pump unit features a stand-by pump and separate electric circuits. The units are started up and switched off as a function of pressure and can be controlled via one or several remote ON-OFF limit switches at a wall hydrant.

The discharge and suction side of the pump are each equipped with a lockable valve which prevents any unauthorised person from closing the valves and thus stopping the unit. The pressure switches and limit switches are monitored for broken wires and short circuit to make sure the pressure is maintained and the unit is always ready for fire-fighting. Both units meet the criteria of the new DIN 14462 standard for fire-fighting water systems, which is valid since April 2009. www.ksb.com

Compact, aseptic control valve

Addition to magnetic drive range

Flow measurement specialist BadgerMeter has developed a compact aseptic control valve suitable for use in bioreactors, pharmaceuticals, biologics and food processing. The Series SCV-09 is a modulating diaphragm style valve which meets the manufacturing standards established by the 3A Sanitary Standards.

Another non-metallic magnetically driven gear pump has been added by Pulsafeeder Inc to its Eclipse range.

The diaphragm valve uses a patented sealing arrangement which avoids the metal-to-metal

contact which could result in metal particles being released into sensitive products, while giving a similar level of control to a metal plug and seat. The self-draining, isolated seal design enables the valve to be used in applications where quick assembly and disassembly for effective cleaning is essential, such as clean-in-place (CIP) and sanitize-in-place (SIP) processes. www.badgermeter.com

The Eclipse 125 has a wider drive gear, idler gear, and liner, making it easier to increase flow without overspeeding the pump. It is made of engineered fluoropolymer, carbon graphite, and graphite impregnated silicon carbide bearings making it suitable for corrosive fluid applications.

Electric pump for difficult conditions UK manufacturer Boltight Ltd has developed an electric pump designed specifically for bolt tensioner applications in the wind turbine industry. The TowerPack delivers a maximum pressure of 2000 bar/29,000 psi and is suitable for tough use in difficult conditions. It offers durability and reliability when working in wet, windy, remote and harsh environment and is IP56 protected, the company says. www.worldpumps.com

The electric pump is built around a steel frame with an integral swivel lifting point. The frame has been balanced to keep vibration to a minimum. It features a full pendant control interface with a simple digital pressure read out. High oil flow ensures the pump reaches the desired operating pressure very quickly. The pump offers on board diagnostics, high and low pressure filtration with

in-built sensors and a high-pressure quick connect port. The user can select the optional constant pressure operation if required. www.boltight.com

Boltight’s electric pump for wind turbines.

The non-metallic gear pump has only 16 parts that are self aligning and allow for easy maintenance and ease in ordering, the company says. The pump can be entirely serviced from the front and leakage is reduced. Its universal motor adaptors can mate up to multiple NEMA and IEC motors while the universal flanges mate to both ANSI and DIN flange connectors. www.pulsa.com

Anti-clog technology for impellers

Caprari offers submersible protection

ITT has introduced anti-clog impeller technology for its small N-series of wastewater pumps.

impeller design is coupled to a specially developed relief groove and is self-cleaning.

The Flygt N-3085 impeller moves axially to improve flow and help eliminating clogging under difficult of conditions. When detritus enters the volute, the patented N-hydraulic pushes them from the centre to the perimeter of the inlet. Moving axially also enables very large detritus to get through. The

ITT says that the new impeller significantly improves the anti-clog characteristics of the company’s Flygt N series of pumps. “This is a giant step in the development of our N-range for wastewater pumping,” says Ulf Arbeus, R&D Director of ITT Water & Wastewater.

MotorGuard, a control monitoring and protection device for the company’s E series of electric submersible pumps, has been developed by Capari. The device has been specifically designed for the company’s submersible units but it can also be used with every electric pump unit in the range for all existing applications, Caprari says.

www.itt.com

The MotorGuard series includes the MG1, which is built into the panel base, and MG2, which is built into the panel front. MotorGuard is equipped for complete, up-to-the-minute control and monitoring functions and has a single, user-friendly procedure for setting all the parameters, Caprari says. www.caprari.com

Duel rate syringe pump

Diaphragm design lengthens life

A syringe pump with two independent pumping channels linked through hardware and software has been introduced by KD Scientific.

Flotronic Pumps has developed a new diaphragm design for its range of air-operated double diaphragm pumps that could help the diaphragm last longer.

The Gemini 88 pump can infuse simultaneously at different rates, or infuse with one syringe and withdraw with the other. When combined with a valve box, the Model 88 can provide continuous delivery, the company says.

The Gemini 88 is designed for continuous operation 24/7 with a range of syringes from 0.5 μl up to 140 ml. The pump has high pressure capabilities and TTL and RS-232 interfaces for data acquisition and control. The communications ports enable daisy-chaining up to 100 pumps. www.kdscientific.com

Currently, the diaphragms in the pumps feature an ‘inside out’ concept that enables fluid to pass between the diaphragms directly through the pump centre with air pressure operating on the outside. The pump is held

together with one nut situated on the opposite side of the pump from the external air valve. After review, a ‘mid-shape’ diaphragm design was conceived which has proved to be longer lasting than traditional diaphragms because the revised shape results in less stress. It is also easier to fit than its predecessors. www.flotronicpumps.co.uk

Current diversion ring helps VFDs Inpro/Seal Company has developed current diversion ring (CDR) technology for motors using variable frequency drives (VFDs) to adjust the speed output of alternating current (AC) motors. According to the company, VFD-controlled motors can produce destructive shaft currents that must be redirected around the bearings, otherwise they can be destroyed. Inpro/Seal’s CDR safely diverts these currents and saves the motor bearings. The CDR components are made from corrosion resistant bronze in any shape or configuration required, and are available as a ‘press-in,’ a ‘clip-on,’ a ‘split’ configuration or an ‘MGS’ design, which prevents contamination from entering the motor bearing enclosure while diverting destructive shaft currents. www.bearingisolators.com www.worldpumps.com

It also includes a filter for use in submersible mode, or when the filter is removed, the pump can be used inline. www.itt.com

Shell Lubricants has added a new lubricant to its Tellus hydraulic oil range that could help increase the energy efficiency of hydraulic systems. In tests, Shell Tellus EE helped companies reduce the energy consumption of their hydraulic machinery by an average of 8% while also protecting equipment protection and extending oil maintenance intervals. Shell Tellus EE is the company’s first synthetic hydraulic fluid that has been specifically designed to help improve the energy

efficiency of the machinery in which it is used. The fluid contains a patented additive technology. “Shell Tellus EE exceeds the maximum test duration of 10,000 hours in the industry TOST[1] test used to assess the oil life of hydraulic fluids, as well as demonstrates wear levels in hydraulic pump tests way below the levels often set by industry standards or certain OEM limits,” said Dennis Woodley, Shell Hydraulics product application specialist. www.shell-lubricant.com

No lubrication for vacuum pump Italvacuum’s Saurus939 vacuum pump now incorporates the company’s LubriZero system, featuring Teflon materials that are resistant to corrosion, do not require any lubrication and reduce nearly to zero oil consumption. According to the company, the system also makes it possible for the pump to use synthetic FDA approved oils. The Saurus939 vacuum pump is now suitable for all chemical and pharmaceutical processes such as drying, distillation and reaction and recovery of www.worldpumps.com

extracted solvents, the company says. The pump can transport common solvents such as methylic alcohol, ethylic alcohol, chloroform, acetone, ethyl acetate, methyl chloride, benzene, toluene, isopropylic alcohol, ethyl ether and heptanes along with more aggressive chemicals such as hydrochloric acid, acetic acid, chlorobenzene, dimethylformamide, acrylonitrile, dichloroethane, cyclohexane, pyridine, dimethyl sulphoxide and dichloromethane. www.italvacuum.com

Micro-dosing component materials

Lead-free formula for bearings

Fluid Research Corporation has introduced MicroShot, a line of small pumps for micro-dosing both single and dual component materials.

Graphite Metallizing Corp has developed a range of its Graphalloy bronze metal grades that do not contain lead. The lead-free formulations are suitable for use in bearings and bushings where the potential for lead contamination is unacceptable, and pump applications include deep-well and potable water pumps.

Micro-dosing is dosing a single component (1 part medium) in volumes as small as .004 ml (4 microns), while micro meter mix

is the dosing of dual component (2 part media) in volumes as small as .008ml (8 microns). The continuing miniaturization of products manufactured has created a demand for micro dispensing, the company says. http://www.fluidresearch.com

MicroShot small pumps for micro-dosing.

Bearings made from the Graphalloy lead-free formula.

The no lead bronze formula has also been accepted by the FDA as suitable for many food-grade applications. Graphalloy bushings and bearings are non-galling and are dimensionally stable when submerged, under load or experiencing

wide temperature swings. The range of grades can withstand temperatures ranging from cryogenic to +1000°F. The bushings and bearings are self-lubricating and are suitable for applications where maintenance operations are infrequent. www.graphalloy.com

Mono NOV and Water For All, an African non-governmental organisation, have developed the ‘Fun Pump’, a water system made up of an electric pump powered by a solar panel and a children’s merry-go-round. The electricity generated from both the power of the sun and the merry-goround provides a significant increase in water production over manually operated pumps, the organisations say. “The strength of the Water For All programme combined with our proven technologies and wide distributor network across Africa will allow us to bring clean water to thousands of communities and make lasting changes in the health and well-being of children,” said Paul Naylon, GROUP MD of Mono.

Depending on the depth and yield of the borehole, the Fun Pump’s solar panel can produce a minimum of 5,000 litres of water per day. When the merry-goround is in use, production increases by approximately 20%. The system also comes with a pump, a 160 Watt solar panel, generator, storage tank and tap. In addition to the Fun Pump, Mono and Water For All have also worked together to develop the Sun Pump, a 480 Watt solar pump that is capable of producing 8,000-30,000 l of water a day based on the specifications of the borehole. The Sun Pump comes with several pump options, allowing it to work in a variety of settings and depths. www.waterforall.org

‘Super-tough’ rotating unit seepex’s MDP series of progressive cavity metering pumps now features a rotating unit made from Xytel ST801, said by the company to be a ‘super tough’ nylon which is virtually unbreakable, is more resistant to abrasion than stainless steel, and runs at low speeds and under high pressure. While conventional progressive cavity pumps generally have a rotating unit consisting of ten individual parts, the rotating unit in the MDP series is injection moulded as a single piece, which is less expensive than conventional units, easier to maintain, and much faster to replace, seepex says.

The new MDP progressive cavity metering pumps provide pulsefree metering of low- to medium-viscosity fluids with repeatable accuracy up to ±1.0%. The pumps are available in four sizes with capacities from 0.1 to 580 l/h (2.5 gpm) and pressures to 12 bar (174 psi). Pumps featuring the Xytel ST801 rotating unit are suitable for industrial wastewater, flocculants and other water-based chemical solutions, emulsions or slurries. seepex says that they are not recommended for use with aggressive chemicals such as concentrated chlorides, ketones and most hydrocarbons. www.seepex.com www.worldpumps.com

Protecting the LNG process with glass seals Special process equipment is required to transport cooled liquefied natural gas (LNG) from pipelines to tanks. But it can easily cause havoc with electrical connections if it breaks the seal around the pumps used to transport it. New sealing technology developed by Schott uses glass ceramics to create a completely closed seal and ensure no gas escapes.

he demand for natural gas is on the rise – and with it the need for suitable means of transportation. However, pipelines are expensive and they often cross through politically unstable regions, allowing suppliers to cut off the supply should they choose to do so. This is forcing manufacturing and consuming countries to increasingly rely on ships (tankers) to transport the raw material. Around 270 such tankers are currently sailing on the world’s oceans and another 130 have already been ordered and should be launched by 2011. Of these, 45 are for Qatar alone, the world’s largest producer of liquefied gas.

Tanks in tankers Before it is shipped, the gas is liquefied by cooling it down to minus 165°C and then pumped into the tanks on board the ship. This means that 600 times as much gas can be stored in comparison with normal temperature. While it is being pumped, liquefied gas is subjected to a high pressure of up to 150 bar. The chassis and internal electric motors of the pumps, which are a permanent component of the tank’s cladding, are immersed in liquefied gas. For this reason, they must be sealed perfectly, particularly where the electrical connections from the deck of the ship lead into the pump. To do this, glass ceramic specialist Schott uses a sealing technique called a compression seal. “This calls for both the glass isolator and the copper conductor to be placed inside a stainless steel housing and then be heated up so that all of the elements melt together,” says Dr. Oliver Fritz, technical manager large scale feed-throughs at Schott Electronic Packaging in Germany. “As the assembly cools down, the glass solidifies and the stainless steel housing contracts to a greater degree than the glass. Due to the differences in the coefficients of thermal expansion of the materials used, the glass isolators are subjected to compression and a hermetic joint is created,” he adds.

the housing of the feed-through continues to contract, exerts even more pressure on the glass and, thus, helps ensure that it remains sealed. Unlike the epoxy grouting often used for these types of seal, the pressure barrier in the glass seal does not contain any organic ingredients that may age when exposed to severe temperature cycling and, thus, lose their hermeticity. In addition, when compared to hermetic pressure barriers that feature a ceramicmetal bond, glass feed-throughs are less likely to experience breakage. Schott started manufacturing the first glass-to-metal feed-throughs for liquefied gas applications 25 years ago.

Testing for strength Because feeding electrical conductors through to the submerged pump represents a rather sensitive area, it is necessary to ensure that the glass seals are carefully manufactured. “We are capable of supplying all types of products together with certification in accordance with the European ATEX standard and the international IEC standard for electrical safety,” said Ulrich Dirr, sales manager large scale feed-throughs at Schott.

“Before it is shipped, each and every liquefied gas feed-through is subjected to one and a half times the maximum required design pressure and then tested for density using helium mass spectrometers.

Ducking energy costs with VSDs A European duck meat producer wanted to save energy and reduce costs by improving the drive control of its refrigeration plants, the greatest consumers of its electrical power. Installing variable speed drives from ABB helped it accomplish this – and led to it installing drives on many other types of plant in the Lincolnshire, UK-based factory.

C

herry Valley Farms is the largest producer of duck meat and duck products in the UK. It processes 45,000 ducks per day, weighing from 2 to 4 kg. Each duck is chilled, and the chilling plant is a major part of the factory’s operation and accounts for a high proportion of its operating costs. Because of this, the manufacturer wanted to explore ways of reducing its energy costs.

“I read in a magazine about an ABB case study where low voltage AC drives had been used by Northern Foods to save energy,” said Darren Bolton, operational improvement manager at Cherry Valley. “We contacted the UK governmentbacked Faraday Partnership to seek advice on variable speed drives, as well as ABB and its channel partner Inverter Drive Systems (IDS).”

Avoiding interruption In the food and beverage industry, the refrigeration plant is often the single greatest consumer of electrical power. The plant is often sold in a price sensitive market, so the users tend to use direct on-line control as standard in order to keep costs down. This means, however, that that it is much harder to vary the speed of motors and save money. Moreover, most refrigeration plant users are wary of carrying out modifications for fear of interrupting the process – and do not generally have the confidence to make the conversion to variable speed drives without specialist knowledge and support.

A duck meat producer reduced energy costs by £25,000 a year after installing VSDs in its refrigeration plants. www.worldpumps.com

ABB’s partner, IDS, looked at finding ways to implementing energy savings. This project initially involved setting up a seven day energy analysis of the existing direct on-line controlled condenser fans, in order to establish operating costs at fixed speed. The four fans had a combined measured power of 38 kW.

“The condenser fans are important due to the nature of the operation,” said Blaise Ford. managing director of IDS. ”In the first stage of the refrigeration cycle, the refrigerant high pressure liquid expands and absorbs heat from the ducks being cooled, turning into a warmer gas. This gas is then compressed. The compressor transforms the vapour from a low-pressure gas into a high-pressure gas. “The refrigerant gas enters the condenser, where fans are used to help cool it down to atmospheric temperature and turn it back into a liquid, ready to expand and cool once again,” he added. “We used the head pressure signal to control our drive to keep this pressure perfectly at its design point, varying the fan’s speed to meet the chilling demand. Previously, at Cherry Valley, this was only an on-off cycle – the ABB drives also reduce the inherent energy wasteful ‘cycling’ of the original control.”

Payback from installation Cherry Valley Farms decided to install ABB standard drives, which were controlled

by the existing sensors for compressor fixed head pressure. It then carried out a further seven day energy analysis and calculated the savings and payback periods. It was shown that the drives had saved 13kW in total representing an annual saving of £7,400.

“We used the head pressure signal to control our drive to keep this pressure perfectly at its design point, varying the fan’s speed to meet the chilling demand.” As well as the energy saving on the condenser fans, the reduced on-off cycling of the refrigeration plant led to a further 10% reduction in compressor power reduction. It also significantly reduced fan noise, improving the environment for neighbouring properties. Cherry Valley Farms has also installed drives on several other types of plant in the

factory, including air compressors and water pumps, and now makes energy savings of £25,000 a year after installing £16,000 worth of ABB standard drives This represents a saving of 49.6% of the energy previously consumed by these applications. The original forecast estimated that payback would be in 12.6 months but actual payback time was only 7.7 months.

Low motor power There are many areas where drives could be used but IDS were excellent in genuinely only picking up on those that could really make a saving,” said Bolton. “Those compressors that were working fine were left alone at IDS’ recommendation. Their theoretical results were all backed up with good graphs and charts.” In the past, many end users have focussed on large power applications for their energy saving projects. This case study demonstrates that applications using motors with powers as low as 5.5kW can produce significant returns. www.abb.com

Going underground to ensure dry cables The population around Stockholm, Norway, is developing rapidly and new homes are needed. A range of hard-wearing submersible pumps have helped to transport contaminated water from a cable tunnel installed deep below Stockholm, making it possible to power a whole new generation of buildings for the growing city.

T

he Baltic Sea region could be one of the fastest developing regions during the next few decades. By 2030, Stockholm is expected to have 25% more inhabitants than today, and these people require homes in one of the most densely populated areas in northern Europe, an area divided down the middle by Lake Mälaren and the Baltic Sea. In Stockholm, this growth is shown by the large quantity of construction projects currently on the go. Modern technology is transforming the city making it possible to quickly receive and integrate new inhabitants. One of the things making it possible to erect 3,000 new dwellings within the space of a few years is the installation of seven submersible pumps deep in the bedrock below south Stockholm. These pumps are designed to keep a high voltage cable tunnel dry.

Tunnel construction ”We are working on five parallel fronts at the moment, enabling us to maintain a pace of around 80 to 100 m per week,” says Peter Ahlgren of Oden Anläggningsentreprenad, blasting supervisor for the new high voltage cable tunnel. The work started in January 2007 and tunnel blasting is scheduled for completion by April 2010 with a further year before the tunnel is fully operational.

residential area will now be replaced with cables laid through the new tunnel. This in turn will provide sufficient land near the city for some 3,000 new homes.

“The water near the drilling rig is full of drill cuttings which act like a kind of liquid sandpaper.” The total length of the main tunnel is 6.3 km, with an additional 800 m of approach tunnels. The depth varies from 30 to 60 m. Two of the five tunnel fronts are blasted from the middle outwards and accessed via a subterranean transport tunnel. Work on both fronts takes place in turn, blasting on one while clearing away the rubble on the other. On the east front a wheeled loader is fully occupied with lifting away about 80 m3 of rock that is taken out of the tunnel to various stone crushers by lorry. On the west front, the rock is granite with seams of diabase, a very hard stone, which means that wear on the drill bits is harsh and the drills need large quantities of cooling water.

Wear and tear Reliable pumps are needed to keep operations going, having to operate continuously to keep the water out, and a breakdown would have immediate and serious consequences. ”It is very important for the pumps to work properly if we are to keep up to the schedule,” says Ahlgren. ”We need to pump out 300 l of water every minute when we’re drilling. It’s 50 m to the surface, so the pumps need to stand up to a good deal of strain, but so far they have functioned well and we are working according to plan.” Wear and tear on the pumps is considerable, because the water near the drilling rig is full of drill cuttings which act like a kind of liquid sandpaper which rubs constantly on the internal parts of the pumps. The company is using two models from its most recent pump series: the Major N-pump which can deliver more than 35 l/s (over 2 m3/min), and the Master H pump which has a delivery head of more than 45 m. “These are especially strong and hard wearing and built to withstand these kinds

The cable tunnel is 6.3 km long and up to 60 m deep.

of conditions,” sayd Per-Åke Jägren from pump supplier Grindex. “They incorporate an entirely new design, where the abrasives in the water are kept away from the sensitive parts of the pump. Our own tests show that these pumps last three times longer in hard wear and tear situations like these. What we are witnessing here confirms our own tests.”

”This water is almost like gruel. The mixture clogs up the system quickly if the plant is not correctly built and dimensioned.” The water is pumped up from the lowest parts of the tunnel pipe to ground level, 50 m up, with the pumps working in stages using sediment tanks along the way. The water is pumped from the drilling rig to a pump pit, where the water is pumped to the next intermediate station, containing the system’s large sediment tank. At this point, most of the remaining drill cuttings are separated from the water and the water pumped on upwards is in large clean. Water samples are taken regularly to ensure that municipal water regulations are obeyed.

Regular servicing A Grindex Master pump installed closest to the drilling rig is most exposed to the drill cuttings in the water. ”This water is almost like gruel,” says Ahlgren. ”The mixture clogs up the system quickly if the plant is not correctly built and dimensioned. Grindex recommend 2000 running hours between services, but we service the pumps every 1500 hours to be on the safe side. In practice this means the shortest service interval for the pump system is two months. However, we carry out a standard daily inspection of the equipment.” ”We’ve been operating at full speed down here since the end of April and everything has worked properly,” he adds. ”We have now come some way into the tunnel construction and are working at maximum speed. It is important to us to be able to maintain this tempo and reliable equipment is essential. Just because the pumps are scarcely noticeable when you pass by them in the tunnel does not make them less important. If one of them were to stop, everything else would stop too.” www.grindex.com www.worldpumps.com

Steering an even keel with effective drainage When archaeologists discovered a haul of 16th century shipwrecks at a Norwegian building site, they realised that quick and efficient drainage had to be attempted to ensure both safe examination of the ships and timely completion of the building. A range of Tsurumi drainage pumps provided the answer.

A

s builders began to prepare the ground for the construction of a new highway tunnel in Oslo, the excavators were not prepared for what they were about to find buried under the mud. As work progressed, the largest collection of old shipwrecks ever found in Norway was gradually uncovered.

Tsurumi LB-480A contractor pumps drain the excavation site, as archaeologists oversee the safe recovery of the shipwrecks.

Specialist archaeologists from the Norwegian Maritime Museum stepped in to examine the site and were surprised to discover the remains of at least 14 wooden boats. Some wrecks measured up to 17 m (56 ft) and are believed to date from the late 16th and early 17th centuries. The boats probably sunk sometime after a massive fire swept

the wooden buildings of old Oslo in 1624. After the disaster, the Danish-Norwegian King Kristian IV had ordered Oslo city centre moved before reconstruction started. The wrecked boats are all fairly well-preserved due to the mixture of mud and fresh water at the site, which is located where the rivers run into the sea at Bjoervika, which part of Oslo’s old port. It became a remote area after the city was moved.

A quick process According to Lin Hobberstad, an onsite archaeologist who oversaw the safe recovery of the shipwrecks, the removal process to recover the boats had to take place as quickly as possible so that the ships could be examined and ensure that construction work on the tunnel could start again quickly. “Oslo Vei, a construction specialist based in Oslo, recommended Tsurumi pumps for the onsite drainage,” she said. “Good reliable pumps are an essential part of an archaeological project like this and Tsurumi was an obvious choice.” The company installed 70 Tsurumi LB-480A contractor pumps which are single-phase portable pumps with level sensors which start and stop the pump automatically. The LB-480A’s electrode level sensor responds to the level of water, switching on the pump as it rises. As the water level drops away, the automatic timer switch stops the pump after just one minute. This helps alleviate the

problems associated with allowing a pump to operate non-stop, including greater wear and tear and more frequent maintenance. Energy consumption can also be higher leading to greater energy bills for the contractors – and more CO2 into the atmosphere.

“The removal process to recover the boats had to take place as quickly as possible so that the ships could be examined.” The pumps also feature dry running which helps avoid damaging the pump, and reduces the need for higher staffing costs. The 0.48 kW power-rated LB-480A is also robust and durable during long periods of continuous use, pumping up to 225 l/m at maximum capacity. A combination of a rubber pump chamber and a urethane vortex impeller provides wear resistance, vital for the water in this kind of application which contains sand and silt in suspension. The pumps are due to remain onsite until the end of construction in 2012. One of the archaeology team dealing with a semi-submerged Tsurumi drainage pump.

Beefing up cattle feeding efficiency A US beef producer uses corn-distilled soluables (CDS) as a feed ingredient to condition its cattle. To make loading, transporting and storing the viscous CDS as easy as possible using tanker trucks, the company opted for four Gorman-Rupp Super T-Series pumps. They proved both reliable and easy to maintain.

L

ocated in Central California, Harris Farms Inc. has been a successful family-run operation since its beginnings in 1937. Since its founding in Fresno County, Harris Farms has grown into one of the largest family-owned, vertically integrated agribusinesses in the US. The Harris Ranch has perhaps become best known for producing the quality beef. It has a fully integrated production system controls every aspect of beef production, from cattle procurement to feeding, processing to distribution. All cattle are fed and processed at separate facilities. Harris Feeding Company currently employs approximately 200 people and

has a capacity to feed 120,000 head of cattle. However, the company is more than a typical ranch or farm, and does more than just supply grocery stores and restaurants with beef. Under the direction of feedmill superintendent Ken Zeman, the company operations include a cattle feed manufacturing facility that stores and transports corn-distilled soluables (CDS), which is a byproduct of ethanol. CDS is used as a feed ingredient, and protein source, as well to condition the feed before feeding the cattle. To pick up the CDS, the company sent its trucks to ethanol production facilities, where it was purchased and then loaded into a tanker truck trailer. To mount the arduous task of quickly and efficiently moving the CDS, in order to maintain a quick operational efficiency while minimizing man-hours, Zeman brought Bogie’s Pump Systems onboard. Zeman had first worked with the company when he rebuilt a pump that was used for unloading Pre-mix. At that time, Zeman mentioned the CDS transportation and storage problem he was facing, and felt confident in the capabilities and knowledge of the team at Bogie’s to help him move forward with the project.

Four Gorman-Rupp Super T-series pumps provide reliability for Harris Ranch, a US beef producer. www.worldpumps.com

To make loading, transporting and storing of the CDS as seamless as possible, Cameron Storrar of Bogie’s Pump Systems had to find a way to quickly load and unload the fleet of eight tanker trucks travelling between the Harris Feeding Company and the ethanol plants. “There are

four unloading pumps and we can unload four trucks at a time,” said Zeman. “When I told Storrar about our need to transport approximately 17 loads of product a day, and then transport it to the mill where it is then pumped through unloading pumps, he saw our problem and began to design a solution that would meet the needs of our company.” Storrar began to implement a solution that not only provided for the transportation and storage of CDS, but could also do it efficiently and safely. In this particular case, the challenge was to unload as many trucks as quickly as possible, deliver the CDS to the storage unit and then to turn around and make another run. A properly working pumping system was key to ensure that this side of the operations ran smoothly. Since CDS is a thick, pasty substance with a degree of acidity to it, Super T-Series stainless steel pumps were selected.

Easy maintenance “For the unloading pumps, Harris Feeding Company opted for four Gorman-Rupp Super T-Series pumps,” said Storrar. “The reason why I chose the solids handling pump for this application was because the customer specified they didn’t want a special pump that would take a long time to get parts for or that was hard to repair,” continued Storrar. With the Super-T technology, design features such as an external shimless adjustment, dual protection of bearings and an ‘easy-grip’ cover plate handle make maintenance easier for the growing cattle operation.

common pump from Gorman-Rupp in order to ensure that we constantly have that model in so that if there were any maintenance issues, they could be addressed swiftly with very little downtime,” said Storrar. The fifth pump that was installed by Bogie’s serves a different purpose – it’s an unloading pump that is fully automated and it transfers the product from the storage tanks to the working tanks and from there it is pumped back into the feed. There, the CDS is mixed into the feed mill, which is the onsite feed manufacturing facility that is located at the Feedlot.

The solution that was put into place makes the loading and unloading process efficient and easy to maintain. “When the pumps came in, they were ready to go. All we had to do was hook up power and we were off,” said Zeman. “The project cost was about US$500,000 and the project return on investment was very attractive. To meet growing environmental and government requirements, the farm of the future will undoubtedly be a cutting-edge enterprise. www.GRPumps.com

Because CDS is a thick, pasty substance with a degree of acidity to it, Storrar needed a pump that could handle the viscous liquid it was transporting. As CDS is different from most fluids pumped, it requires that certain parameters be met in order to move the somewhat dense substance. Even though Harris Feeding Company had some previous experience with GormanRupp pumps, none were as large as the ones that pump straight into the mixer box. “I’ve used some of the smaller pumps, which were Super T-3’s and they just perform. I haven’t encountered any problems, and Storrar will probably be retired before I have to replace that one – and I think that will be many years down the road,” said Zeman. With easy installation, the Super Ts are able to unload a truckload of 52,000 pounds in 12 minutes. “I chose the most

Pumps as turbines for water industry Running pumps as turbines is a well-known concept in the water supply industry. It is seen as an efficient method of generating power as well as recovering energy and contributing to savings. There is the added benefit that pumps are less complicated to operate than turbines. Bryan Orchard reports.

T

he concept of running a centrifugal pump in reverse rotation mode has been recognised by pump manufacturers for many years and within the water supply industry this concept has been exploited to a limited degree as a means of generating power in locations where it is considered too expensive to purchase a hydro turbine. It has not gone unnoticed by water suppliers, operators of small hydropower plants and pump manufacturers that running pumps as turbines (PaTs) is an efficient method of generating energy as well as recovering energy and contributing to energy savings. In the current world economic climate where reducing energy costs is becoming a high priority it is not surprising that PaTs are starting to create significant interest.

manager, Small Hydropower. “In the small end market power requirements are typically up to100 kW, but the investment costs are relatively high for conventional hydropower units and the payback period can be as high as 15 years. With our PaTs solution, the payback period can be as short as three years and there is the added benefit that pumps are less complicated to operate than turbines.”

that, PaTs can also have a role to play in locations where the power supply is readily available and reliable. KSB is now supplying systems for very large water supply infrastructures which traditionally have been the domain of conventional hydroturbines. Here the power being generated is contributing to the overall running costs of the water pumping stations and putting power back into the national grid.”

He continues: “For locations where there is a relatively constant water supply but power supplies are unreliable or even nonexistent, PaTs are a simple and economic approach to generating power. Not only

Identifying the potential for running pumps as turbines originated when users in the water industry wanted to know what the impact would be on their systems should a pump stop and

KSB Aktiengesellschaft is one of a group of pump manufacturers that is active in investing resources in PaTs and the company has recorded considerable success with its solutions in several parts of the world. Applications where KSB already has pump units on PaTs duties include small hydropower systems (<10 MW), major water transport systems, reverse osmosis and industrial systems where the technology can be employed as an alternative to throttling devices. “KSB has been active in supplying volute casing and ring-section pumps for PaTs duties over several years, mostly into the small end of the hydropower market,” says Sander Klos, KSB’s senior project www.worldpumps.com

to providing energy has been successfully supplied by KSB to locations in many parts of the world where a power supply is not available for operating water distribution/ transfer pumps but there is sufficient energy in head of water to drive the PaT.

then go into reverse operation. This was a scenario which was raised with KSB and in response its hydraulics engineering department was brought in to examine this issue and to calculate the turbine performance curves of pumps when running in reverse. They discovered that the behaviour of the pump running as a turbine is very good as the energy output could be higher than the energy input used to run it as a pump. Hydraulically, the pump in turbine mode can handle a higher volume of water than when in conventional pumping mode. There is a higher flow inside the pump and this means that the amount of energy that comes out is higher. An added bonus is that when it is in reverse operation and running as a turbine the pump runs more efficiently than in conventional mode. The operating range for ring section and volute casing pumps is illustrated in Figure 1.

Cost-effective power With the pump running in reverse, the shaft torque can be utilised in a number of ways. When attached to a generator it is the mains frequency that determines the speed. In such a scenario to generate a frequency of 50 Hz the pump as turbine would have to run at a rate of ~1515 rpm (a little over-speed). Incorporating frequency inverters and appropriate mains feed circuitry would create greater speed variation without adding very much cost to the package. It can be seen, therefore, that this is a very cost-effective way of generating power even when compared to the higher efficiencies of a conventional turbine. An alternative application would be to connect a PaT directly to a driven machine, another pump being an example, which does not have either a motor or generator to fix the speed. This mechanical solution

In order for this type of unit to operate effectively both the PaT and pump must have ‘equal output’ at both ends of their shafts, which means that they must be rigidly connected to each other by couplings or a gearbox. If the Pat does not have sufficient strength, then the pump to which it is connected will not be able to provide the necessary discharge head. On the other hand, if it is too strong, the Pat will either waste energy or overload the pump. Because of its exposure in all sectors of the global water supply industry, KSB has products that have been proven over many years. Pumps that the water industry will be more than familiar with are the Omega, Etanorm, Multitec and RDL ranges and it is these products that KSB is advocating for hydropower duties for heads above 10 m. Where the head is below 10 m and flow rates are high, then axial flow pumps provide the most effective solution. The scope and operating capabilities of these pumps has enabled KSB to establish a business sector dedicated to designing PaT modules which can be used in single and multiple configurations (see Figure 2). The capability to operate multiple PaT modules is highly relevant for locations where the water supply can fluctuate. Unlike conventional turbines, PaTs do not have adjustable guide vanes for adapting to fluctuations in the water supply and this is perceived as a drawback to their use. By employing a number of differently sized units to distribute the total volume of water available, this difficulty can be overcome. According to KSB, running several units requires only the minimum of control and although this type of arrangement does diminish the cost advantage of the PaT over the use of a single turbine, it remains advantageous in terms of appropriate technology. Quite simply, pumps are easier to operate and maintain that conventional turbines. ■

Design and performance

Improving open canned systems The results of a study on the hydraulic performance of open-bottom canned pump intakes should aid engineers and pump users to design these systems with reduced velocity fluctuations and undesirable flow rotation. David Sanders of Sunrise Engineering with Steven L. Barfuss and Michael C. Johnson of Utah State University provide the details.

P

ump systems often require the use of an open-bottom canned intake to house the vertical turbine pump. A canned pump can be defined as one in which the pumping unit is housed within a shaft and may be considered in two separate categories – open-bottom and closed-bottom. Open-bottom canned pumps draw water from a horizontal header, which passes flow along the bottom of the open can with enough head to at least submerge the pump bell within the can. Closed-bottom canned pumps are enclosed at the bottom, and water fills up the can by way of an inlet pipe on the side of the can. This article investigates open-

bottom canned pump intakes and the measures necessary to improve hydraulic performance and reduce velocity fluctuations and flow rotation under varied conditions. In open-bottom canned pump systems where the average velocity in the header (perpendicular to the can) becomes greater than the average velocity in the riser, a number of potential problems may arise. Of these, the potential for vortices, flow prerotation (annular flow pattern with tangential velocity occurring upstream of the turbine) to the pump impellers, turbulence, and unsteady and nonuniform flow at the pump throat can

be of particular concern. The problems may be compounded as header velocities increase and as the distance from the pump bell to the header (YBell ) decreases. The previously identified problems can reduce pump efficiency, increase maintenance and, over time, cause damage to the pump. Because of this, the American National Standards Institute (ANSI) and the Hydraulic Institute (HI) have established acceptance criteria for physical model tests of open-bottom canned pump systems. These criteria include having a circulation angle, θ, less than 5°; time-averaged velocities at points in the throat of the bell should be within 10% of the cross-sectional area average velocity; and time-varying fluctuations at a point should produce a standard deviation from the time-averaged signal of less than 10%. The circulation angle is defined as: θ = arctan(Vt /VA) where Vt is the average tangential velocity of the tip of the rotometer impeller, and VA is the average vertical velocity at the pump throat.

guidelines for the benefit of the engineer and pump user. 1. A vortex suppressor is necessary to break up abnormal flow patterns ahead of the pump suction bell. 2. The maximum horizontal header velocity is 1.8 m/s (6.0 ft/s). 3. The maximum riser velocity is 1.5 m/s (5.0 ft/s). 4. The minimum distance from the horizontal header to the bottom of the pump bell is 3.0xD, where D is the inside diameter of the riser. 5. The pump must hang centred in the vertical riser pipe.

6. The minimum distance from the submerged pump bell to the water surface is 1.0xD. 7. Open-bottom canned intakes with flow rates exceeding 315 litres/s (5000 US gallons/min) per pump require a model test. In researching this topic, any background or supporting information available was exhausted, but very little useful information was found. Therefore, data from physical models took on great significance in this study.

Physical modelling As a basis for research, the data from three physical model studies were used. The first was that of an underground chamber with a horseshoe-shaped cross-section, known as Intake Pumping Station No. 3 (IPS3), from which water would be pumped to a water treatment plant and then to a nearby city. In the IPS3 physical model study, a pump forebay (header) using 11 pairs of identical pump shafts (risers) connected to the top of the forebay was modelled. Figure 1 shows a schematic of this model. The second model study used was that of Intake Pumping Station No. 1 (IPS1). The setup of IPS1 was similar in design to that of IPS3, but it had only 10 pairs of pump shafts (risers), and the forebay (header) had a much smaller cross-sectional area and, consequently, a much higher header velocity than IPS3. A schematic of the IPS1 forebay model is shown in Figure 2. The third model study included a single acrylic pipe (riser) that branched perpendicularly off a 61.0-cm (24-inch) line (header). This model was used to determine the similarities between the IPS3 and IPS1 data.

Figure 3. Schematic of the research model test setup.

Figure 3 shows a schematic of this research model. The objective of this study was to determine system configurations that fall outside the HI guidelines. This makes it possible to install pumps closer to the header or operate the system at higher header or riser velocities than the HI guidelines suggest.

The models The pump shafts for the models were constructed of clear acrylic tubing, which enabled the observation of the flow conditions to the pump bells, including vortex formation and persistence as well as other flow rotation. The pump throats

and pump bells were also constructed of acrylic, using moulds to form the bells. The pump bells in each of the three model studies were tested with and without vortex suppressors. Figure 4 shows an example of the vortex suppressors used in these model studies. Acrylic turn columns were fabricated and connected to the pump bells, allowing the bells to be rotated within the risers a full 360°. These turn columns allowed for the collection of velocity data at any position along the circumference of the pump throat using a single permanently mounted Pitot tube and static pressure tap. These instruments were used to evaluate the potential for velocity fluctuation and flow rotation problems at each pump throat. Differential www.worldpumps.com

pressure transducers, which are accurate to 1.0%, were connected to each Pitot tube to measure the velocity head. A rotometer, as described in the HI Standard, was mounted in each pump throat. These rotometers were used to detect rotational flow entering the pump throat, enabling the calculation of the circulation angle. Flow rates through the models were measured using calibrated orifice flow meters capable of reading to within 0.5%. For low flow rates, a weigh tank was used to

With three variables in this study (Vr , Vh and YBell), the ratio of Vr /Vh was used to create a dimensionless control parameter that would facilitate the comparison of different test scenarios. In this ratio, Vr is the flow velocity through the riser, calculated immediately upstream of the bell in the shaft, and Vh is the flow velocity through the header, calculated immediately upstream of the riser. This velocity ratio was used in comparing the hydraulic conditions at varying YBell distances. The tests run on each model had a Vr /Vh ratio range of nearly one order of magnitude. The research model was tested with Vr /Vh ratios ranging from 0.15 to 1.23. In the IPS1 model study, the ratios ranged from 0.58 to 5.8, while in the IPS3 model study, the Vr /Vh ratios ranged from 3.5 to 34.8. While it would be desirable to operate each model over a wide flow range, physical limitations restricted the range of possible velocity ratios. Therefore, while Vr /Vh ratios in the IPS3 model reached 34.8, Figures 5-7 only show ratios up to 8.0 because the IPS1 model and the

Test results Figure 5 (a and b) shows the velocity fluctuation and Figure 6 the velocity distribution, while Figure 7 compares the circulation angle calculated for each test condition. All these figures also illustrate the published HI standard in reference to the actual test data for comparison. The figure icons differentiate between specific model tests and describe the distance from the pump bell (in riser diameters) to the header (#xD). As illustrated in Figures 5 and 6, the velocity ratio had a direct effect on the velocity fluctuations and the mean velocity distributions, with or without the vortex suppressor. The apparent uniform trend of the data for the velocity distributions and the velocity fluctuations both with and without the vortex suppressor is noteworthy. It appears that at higher velocity ratios, the distance from the pump bell to the header (YBell) has a less significant impact on the system. The circulation angle (Figure 7) was reduced by the addition of the vortex suppressor.

Discussion Velocity ratio While the HI’s guidelines are an excellent resource for helping the engineer and pump user design and operate a system that falls within their acceptance criteria for model tests, the velocity ratio used in this research study would be an additional helpful tool that would allow engineers and pump users to change the configuration of the system to meet their needs. This could include having YBell distances less than the distance suggested by the HI, if need be, to access more water. It could also permit the use of higher average velocities in the riser if more water were needed, as long as the correct header velocity was used to achieve an acceptable velocity ratio. With the use of Vr /Vh ratios, the HI design parameters are extended beyond what is presently available. The determination can be made that without a vortex suppressor, at a YBell distance of 1.0xD, Vr /Vh ratios above the ‘minimum acceptance ratio’ of 1.0 should result in conditions that would fall within the HI Standard. Therefore, systems that need to operate at a header velocity of 1.8 m/s (6 ft/s) – the HI limit – would need to keep the riser velocity above 1.8 m/s (6 ft/s). Conversely, if systems need to operate at a riser velocity of 1.5 m/s (5 ft/s) – the HI limit – the header velocity would need to stay below 1.5 m/s (5 ft/s).

Vortex suppressor use The use of a vortex suppressor in these pumping conditions lowers the ‘minimum acceptance ratio’ to 0.63. Therefore, if systems need to operate at the 1.8 m/s header velocity limit with a vortex suppressor the riser velocity would need to exceed 1.2 m/s. For a riser velocity of 1.5 m/s, the header velocity would need to stay below 2.4 m/s. It should be remembered that one purpose of

the vortex suppressor is to reduce vortices, and it may therefore need to be used in conditions where vortices are more likely. Again, these ratios must be used with consideration of the system’s capacity limits in mind. These calculations offer much more freedom to the design engineer and pump user in the event that higher velocities than those given in the HI design parameters are required within the pump system. The circulation angle was lowered by the vortex suppressor. If surface or sub-surface vortices were present in the tests, the vortex suppressor would have played an even more significant role. It should be remembered that one of the stipulations in the HI Standard is that the design and operation guidelines given are especially applicable to pumps that will be pumping 315.5 litres/s (5000 USgpm) or less. The standard suggests that open-bottom canned intakes with flows greater than 315.5 litres/s per pump require a model test.

Conclusions Open-bottom canned pumping systems are subject to a number of potential problems, as outlined in the introduction, which has prompted the HI to develop acceptance criteria for pump intakes. To help meet these criteria, the Institute has also established design guidelines for open-bottom canned pumps. These guidelines include the use of a vortex suppressor, maximum horizontal header velocity of 1.8 m/s, maximum riser velocity of 1.5 m/s, and minimum YBell of 3.0xD, as detailed earlier. The results from the three separate model studies discussed here indicate that the Vr /Vh velocity ratio plays a very important role in determining the ability of a pump system to operate within the HI acceptance criteria. These results will be helpful in predicting pump system performance, based on this ratio and YBell. With these results, the engineer and

pump user will be able to position the pump bell in an open-bottom canned pump system below the suggested 3.0xD using an acceptable velocity ratio. With YBell distances greater than or equal to 1.0xD, a velocity ratio of 1.0 is the minimum acceptable ratio for a pump system. Lowering the pump bell past 1.0xD would require raising the minimum acceptable velocity ratio to 1.4. Furthermore, engineers and pump users will also be able to use Vr /Vh ratios to achieve the needed velocity through the header or riser without turbulence or rotation problems in the pump. A vortex suppressor is recommended for use in these pump systems. It is apparent from the data that as the Vr /Vhratio increases, the velocity fluctuations and turbulence within the pump bell decrease. This implies that the magnitude of this ratio is the factor that plays the most significant role in velocity fluctuation and flow rotation within open-bottom canned vertical pump intake systems, although the ratio is limited by the capacity of the system itself. The YBell distance plays a significant but secondary role in this, giving less stable results as the distance decreases between the pump bell and the header. ■

Energy saving

Blade adjustment cuts energy costs Cooling water pumps for power plants can save energy by adjusting the flow rate. Gerd Witte and Dr Manfred Stollenwerk explain that pumps with an adjustable pitch angle of propeller blades can lead to cost savings. Depending on the load profile and internal energy costs, the ROI can be reached within two to three years.

T

he production of electrical energy is secured by the mix of different power plants. On the one hand side, power plants for the base load are running continuously with a capacity of 100% load. Other power plants are covering times with fluctuating energy demand and therefore running with different load cycles. In time of lower load, these power plants need less cooling water respectively. The usage of cooling water pumps with adjustable flow rate can save energy compared to pumps without the possibility to adjust the flow rate. For the estimation of the energy and cost saving potential we have made a comparison between pumps with a constant flow rate and pumps with an adjustable flow at different load profiles.

adjust the pump to changing head. The ground floor of the inlet chamber in front of the pumps must be excavated deeper due to the length of the pre-vortex controller and its pressure losses, which are resulting in higher NPSHR.

Therefore, this article focuses on the technical solution using propeller pumps with variable pitch angle of the propeller blades. The statements included in this article therefore are valid only for pumps of this type and comparable applications. For other circumstances other control systems may be preferable.

Variable pitch angle adjustment The variable pitch angle adjusting device is mainly consisting of three gears and a hollow drive shaft witch contains the adjusting shaft (Figure 1). The adjusting of the pitch angle can be performed during operation or also during shut-down of the pump. A geared electrical motor is energized, when adjustment is performed. Via the differ-

This relative rotation effects an axial movement of the adjusting element within the propeller hub by means of a threaded bush. The adjusting element is provided with inclined grooves, in which the adjusting levers of the propeller blades are mounted. When the adjusting element is moving axially, the propeller blades are rotating simultaneously by approximately 20° from min. to max. angle. All positions within these limits are adjustable, depending on the duration the geared adjusting motor is energized. The extreme positions are protected by limit switches as well as the max. torque.

Results For both types of pumps we have calculated the characteristic curves of the total head H(Q), shaft power P(Q), efficiency η(Q) and NPSHR (Q). The results are shown in Figure 2 (fixed impellers) and Figure 3 (adjustable impellers). The pump and system characteristic curves are shown for single and parallel operation. The latter is the nominal operating point of the plant at 100% load. On top of the diagrams the characteristic curves head [m] versus flow rate [m³/h] are shown. For the fixed impeller pump there is only one intersection of the Q-H-curve with the www.worldpumps.com

system resistance curve – which represents the operating point – for single pump or two-pump operation, respectively. The curves for two-pump operation are resulting from the addition of the flow rate of two pumps at the same head. This is valid also for the variable pitch angel propeller pumps. For the adjustable pitch angle propeller pump there are several Q-H-curves plotted, each of them for a certain pitch angel, which is noted at the graph. Because it is possible to adjust any number of pitch angels within the possible range from min to max, there is a large operating range of cooling water flow rate available from approximately 30% to 60% (single pump operation) and 60% to 105% (twopump-operation). Please note, that the indicated operating range is not only limited by the min. and max. possible pitch angle, but also by the

For the calculation of energy consumption and saving, we have analysed three different load profiles with an average load from 90% (profile 1), 87% (profile 2) and 85% (profile 3). The details of the power load profiles are shown in Figure 4. The detailed energy consumption is calculated for pumps with fixed impeller blades without flow control and for the pumps with variable impeller blades, where the impellers are adjusted to the optimum operation point of the needed cooling water amount. It can clearly been seen that there are reasonable energy saving potentials, especially for lower power loads. For the estimation of the cost saving we have assumed production cost for the energy of 0,03 € per kWh.

Summary In summary, using pumps with adjustable pitch angle of the propeller blades can lead, depending on the load profile, to cost savings of up to €254 000 per year. Taking the additional costs for the pitch angle control of approx. €200 000 per pump (400 k€ for two pumps) into consideration, a return of investment can be achieved within approx. two years. Please note, that the adjusting gears are active only during the changing of the blade pitch angle, the predominant operating time the gears are free of load. Therefore the maintenance intervals and

Condition monitoring

Keeping track of bearing wear Effective monitoring of thrust bearing wear is a crucial factor in preventing pump and impeller damage. Sensonics’ Russell King describes the techniques available for monitoring thrust bearings on boiler feed equipment, and explains how the technology can be successfully implemented and commissioned.

O

ne of the challenges facing plant instrumentation engineers today is the effective and reliable monitoring of thrust bearing wear in critical pump applications. Typically pumps of this type are in continuous use, and operational downtime is normally only permitted during planned outages. Predicting the wear, and hence the requirement to replace the thrust pads, is essential to fit in with this regime.

driven from the impeller action. Tilting pad thrust bearings, common for the newer BFP designs, use a high-pressurized hydraulic oil supply to minimize friction. This is particularly effective at start up, or slow rotating speeds, where the hydrodynamic effect – which establishes itself at rated speed - is not present.

of excessive wear could be because of inadequate oil pressure or flow around the assembly; a worn balance device can produce uneven forces on the bearing with the same result. Wear rates in combination with vibration measurements can provide a good guide to the best efficiency point (BEP) performance of the pump.

Thrust pad wear indication can provide valuable feedback on how well the lubrication technique is working. Measurement

In addition, thrust monitoring is a key protection measure to ensure automatic shutdown in the event of safe operating

With rotational speeds between 3000 and 7000 rpm, protection against potential pump damage is also key, as excessive thrust wear can not only damage the bearing assembly but also the impeller, resulting in the plant potentially being out of action for six months or more. Condition monitoring specialist Sensonics has been working with plant instrumentation engineers for many years, providing effective measurement regimes through its range of equipment and services.

Monitoring solutions What types of thrust monitoring techniques are available for boiler feed pumps (BFPs)? How is implementation to be achieved? A high-pressure BFP set will operate with pressurized fluid within the thrust bearing. Permissible total wear on the thrust pad from new is typically between 0.75 mm and 1.25mm, before inspection or replacement is required. Older BFP designs use a hydrodynamic (water) lubrication system www.worldpumps.com

limits being exceeded. A recent example is that of a 350 MW turbine set and pump, where a Sensonics thrust monitoring system enabled safe shutdown of the BFP. This prevented bearing damage and a long outage period for the turbine set. While it is fairly straightforward to monitor the end of the drive shaft for changes in pad thickness, the measurement is complicated by the following factors:

t
Shaft and casing expansion t
Float in overall assembly t
Measurement target shape and size. Probe positioning The challenge is therefore a measurement range for the shaft position that covers the mechanical expansion float, yet still provides accurate thrust wear indication. Modern eddy current proximity probes, such as those by Sensonics, are proven in such applications. For example, an 8 mm tip device having a half sensitivity arrangement offers a 4 mm (4 mV/um) range. If a greater range is required, an 8 mm range probe (20mm diameter) is recommended. Special bracketry is usually required to achieve correct probe positioning and adjustment. Dual redundant systems are common, because they help ensure continued measurement integrity in the event of a probe failure. Mounted axially to the shaft, the ideal location is facing the shaft end – drilling and tapping the cover plate is common. If this is not

increments and the linearity of the measurement system is checked – some adjustment at the driver is possible if the target is not ideal. With the set cold and the shaft positioned with the thrust pads against the bearing disk, the probe is set against the target at a gap (typically mid-range), which permits the full measurement range required, including the float. Note that not taking all the shaft conditions in to account could result in the probe being damaged.

possible, or if the target area is insufficient (must be two x probe diameter), a shaft collar can be used, or added, between the thrust and shaft end bearing. This has the advantage of being located closer to the thrust bearing and, therefore, it reduces the measurement error resulting from expansion and other shaft effects. Both probe types can be obtained in a straight or disk format to suit either a direct or collar mounting arrangement.

The monitor unit is adjusted to read zero. If the shaft cannot be set on the thrust pads, it is still possible to set up the zero point provided the shaft position is known relative to the normal thrust pad position. Once rated speed and load are achieved, minor zero adjustment may be required to allow for mechanical expansion. Positive and negative alarm levels can then be set, and from the point of commissioning, the thrust pad wear can be monitored with time.

Proximity probes, such as those by Sensonics, should comply with the API 670 standard and can be obtained in a set range of tuned cable lengths. The probe is used in conjunction with a driver / lineariser to provide a voltage output proportional to gap. To complement the probe system, a thrust monitor and protection unit is required to process the measured signal.

Commissioning To commission such systems, the probe is adjusted against the shaft target at known

In addition to thrust, it is also usual to monitor vibration, temperature and speed on such plant. A wide range of multichannel monitoring and protection equipment is available for these functions. ■

Operating

Applying NPSH to metering pumps Net positive suction head calculations are routinely used to establish whether centrifugal pumps will operate satisfactorily in a given process. However, extending the NPSH concept to metering pumps presents a number of difficulties, as Patrick Deniau of Milton Roy Europe explains.

tables or by calculation, based on suction equivalent length. Component manufacturers give the equivalent length of each of their products (elbow, valve, reduction nozzle, etc.) to facilitate this approach. Friction losses reduce the usable energy.

NPSHr

Combining these system parameters determines the available NPSH (NPSHa)

For their part, the pump manufacturer will qualify their pump, particularly by

at the pump inlet, the determination of which is the sole responsibility of the purchaser.

Centrifugal pumps The NPSH concept is well understood in the centrifugal pump sector and the approach is fully standardized.

NPSHa This is the available NPSH. In the suction tank, we have a certain pressure – minus the liquid vapour pressure at the working temperature to prevent cavitation, this pressure represents the usable energy at the level of the storage tank. The geometry of the installation defines the differential elevation between the liquid level in the suction tank and the pump itself. When positive, the pump is in the flooded suction configuration and can benefit from extra usable energy. When negative, the pump is in the suction lift configuration and benefits from less usable energy. Along the suction pipe, we have friction losses that can be easily determined from www.worldpumps.com

Figure 1. The PRIMEROY®L, the most recent metering pump launched by Milton Roy, offers a minimum positive inlet pressure (MPIP) of more than 8 m suction lift.

measuring the pump’s required NPSH (NPSHr). At a given working point, the pump will be installed with a starving device on its suction line so that the test loop can deliver an adjustable NPSHa. At the point where the NPSHa is low enough to affect the pump’s volumetric efficiency (usually by 3%), the value is normalized as the pump’s NPSHr. This data is the sole responsibility of the pump manufacturer.

Figure 3. MPIP measurement on the newly developed PRIMEROY K pump range.

t
At the end of the suction stroke, the

liquid column is in motion and, due to its inertia, the pump has to decelerate it by exerting an overpressure.

t
Friction losses are greatest at the middle

of the suction stroke when the speed is at a maximum. Except for high viscosities, friction losses do not interfere with acceleration, as they are out of phase with each other.

Impact on NPSH approach NPSH criterion It is the responsibility of the pump supplier to select a pump with an NPSHr below the NPSHa given on the customer datasheet, with a sufficient safety margin (usually 0.5 mlc), that is: NPSHa > NPSHr + 0.5 mlc

Metering pumps Only one clear definition of a metering pump is given by the API675 standard: ‘A reciprocating pump in which precise volume control is provided by varying its effective stroke length. Such pumps are also known as proportioning, chemical injection, dosing or metering pumps’. Being a reciprocating pump, a metering pump generates a highly pulsating flow. Instantaneous flow variation being fluid speed variation, this means that the pump will have to alternately accelerate and decelerate the liquid column. On the suction side of a metering pump this translates as:

t
At the beginning of the suction stroke, the

liquid column must be set in motion and accelerated, which is achieved by the pump creating a relative vacuum to pull the fluid.

www.worldpumps.com

The first problem is that acceleration is largely predominant when compared to friction losses (by a factor of more than 50 in most cases), and must be integrated into the NPSH calculations. As a consequence, pump buyers do not need to take account of friction losses in their NPSHa calculation. A second problem is that acceleration is a function both of the installation (the responsibility of the buyer) and of the selected metering pump (the responsibility of the seller). Typically: Acceleration = 0.016L.Q.N/d² This formula is not a standard across all metering pumps; each manufacturer has its own formula, but they are all basically equivalent. Here, L and d are respectively the actual length (in m) and the internal diameter (in mm) of the suction line; Q and N are respectively the pump’s maximum output (in litres/h) and its stroke speed (strokes per min; spm). Note that, on the installation side, the pipe diameter d is squared and so has a significant influence and, on the pump side, stroke speed N may be a critical factor as well, since a low stroke speed may imply a larger pump, which is likely to be more expensive.

ISO 13710 standard The ISO 13710 standard was published in December 2004 and addresses ‘Reciprocating positive displacement pumps for use in the petroleum and natural gas industries’. In its NPSH section, it stipulates that NPSHa is the responsibility of the buyer, similar to the centrifugal pump NPSH approach, and, as the standard writers knew that there are acceleration issues in the case of reciprocating pumps, they simply add that NPSHa must include acceleration losses. The third problem is that the buyer cannot determine the NPSHa as it is also a function of the selected pump. ISO 13710 also defines an NPSHr for reciprocating pumps, to be provided by the manufacturer. This NPSHr is measured in exactly the same way as for centrifugal pumps. This brings us to the fourth problem: though the NPSHr approach is meaningful in centrifugal pumps as it measures a working point where the volumetric efficiency starts to drop, therefore approaching the point where the risk of cavitation appears, it is not meaningful for reciprocating pumps. Reciprocating pumps are supposed to deliver the same volume at each stroke, and such a measurement simply measures the pump’s ability to work under starved suction conditions, what we call the minimum positive inlet pressure (MPIP), which is the minimum static pressure on the suction side needed for the pump to deliver its volume per stroke (see Figure 3). It is not a sign of incipient cavitation, as cavitation is caused by acceleration, and applies to a very short period of time at the beginning of the suction stroke, independent of MPIP pump performances.

Illustration Some years back, I had an intellectual ‘fight’ with a customer’s witness inspector keen to apply the ISO 13710 NPSH approach. The application was for liquefied gas metering. As usual for these complex applications, the installation was quite simple: a suction tank pressurized at the vapour pressure level (to maintain the liquid phase), with a short, straight suction line providing a flooded suction configuration to the pump. The pressure in the suction tank, minus the vapour pressure (equalling zero at this stage), plus the tank’s relative elevation to the pump, minus the acceleration (not even considering friction losses) was leaving a very low NPSHa… which was below the pump’s MPIP reported in the datasheet. According to the ISO 13710 NPSH interpretation: NPSHa < NPSHr, and… … not any metering pump can do the job! By the way, today, this pump is working well. Why?

t
First, the tank elevation was slightly larger than the calculated acceleration, leaving some usable energy at the pump inlet.

t
Second, the static pressure under which

the pump is working (the pressure in the suction tank plus the tank elevation) was larger – by far – than the MPIP required by the pump. Vapour pressure does not need to be considered here, as the pump does not differentiate if the pressure is coming from a liquid or a gas.

NPSH test Another issue arises here. As for centrifugal pumps, metering pump customers increasingly want to confirm the pump selection by an NPSH test – again, another possible intellectual fight between the parties. Do we want to measure the pump’s MPIP? Easy, but, as illustrated above, it has nothing to do with an NPSH approach whose purpose is to prevent cavitation. Do we want to simulate acceleration? A bit more complex to do, but it is not a real test, as it is a simulation based on calculations. Do we want to really test what the seller says (that the pump will work under the specified conditions)? We would have to reproduce the entire installation (!), using a fluid with the same specific gravity, vapour pressure, etc. Everybody can understand that this is simply not feasible.

Conclusion Trust is the answer! The customer has to provide the manufacturer with the best reliable information on the product and the installation (usually well defined in the datasheets). The manufacturer, for its part, has to make the best appropriate metering pump choice, including the NPSH criterion approach, and give advice, such as recommending enlargement of the suction pipe diameter or shortening the pipe, suggesting the use of a dampening device or a multiplex pump design, and so on. The final, appropriate NPSH criterion for metering pumps, which covers more than 90% of metering pump application cases, is: NPSHa (without friction losses) > Acceleration + 2mlc (the safety margin).

Reduce pumping costs through optimum pipe sizing Every industrial facility has a piping network that carries water or other fluids. According to the US Department of Energy (DOE), pumping systems represent 16% of a typical facility’s electricity costs. The power consumed to overcome the static head in a pumping system varies linearly with flow, and very little can be done to reduce the static component of the system requirement. However, there are several energy- and money-saving opportunities to reduce the power required to overcome the friction component.
