REPAMAX Objectives: √ Connecting pipes of equal outside diameter √ Sealing breaks and cracks in pipes √ Sealing holes √ Absorbing vertical and axial ground vibrations √ Ability to cover threaded connectors up to 3”
The Repamax
Hydraulic Gasket – Mode of operation: A – Water flows into the center of the gasket, and past the fins located at the two ends of the rubber gasket, inflating them so that the fins become tightly pressed against the pipe. This creates the hydraulic seal. B – Mechanical sealing is created by the bolts that fasten the body of the Repamax to the rubber gasket surface, pressing it against the pipe. This provides effective sealing in cases where there is no pressure in the pipe for inflating the hydraulic fins .
THE REPAMAX
Hydraulic gasket – Mode of operation: The hydraulic system provides added value beyond connection and sealing. Through the hydraulic fins, the Repamax can absorb ground shifts caused by changes in weather or resulting from earthquake. The fins move up and down with the pipe, so that the Repamax doesn’t “lock” onto the pipe after closing. This action provides the entire pipeline with flexibility, and reduces further cracking and breaking along the line in the future.
THE REPAMAX Hydraulic gasket – Mode of operation:
THE REPAMAX • All stainless steel, including bolts. • Made by one folding action, with no welding (welds are susceptible to corrosion). • EPDM gasket suitable for drinking water, NBR for petrol and gas (as required). • Can be ordered in 3 widths: 140mm, 210mm, 280mm. • Suitable for all types of hard pipes, including asbestos, PVC, steel, polyethylene, fiberglass, cast iron, and so on. • Every Repamax has a range of 10mm. • Can be ordered in a variety of sizes, from 40mm, and up to over 3,000mm. • Also available as an Outlet Repamax to replace a broken cast iron outlet. and expose wide area • No need to cut pipe destroying field crops or infrastructure.
THE REPAMAX •
Repamax opens, so that for sealing holes, there is no need to cut the pipe. Instead, Repamax wraps around the pipe, thereby repairing it. Choosing the right Repamax to suit your needs:
• • • •
Measure the external circumference of the pipe in mm. Divide the result by 3.14 (Pi) to find the diameter. Look on the charts to see which Repamax suits the required diameter. Decide on the width of the Repamax based on the required area to be covered.

EZ-MAX
THE EZ-MAX EZ-MAX was designed to seal holes in pipes. EZ-MAX is the only clamp that allows a range of 20mm. Available in 4 sizes: 150mm, 225mm, 300mm and 600mm. Suitable for diameters from 1.5” up to 12” as standard, and larger sizes may be ordered. No need to cut the pipe. EZ-MAX opens and wraps itself around the pipe. Made of stainless steel (including bolts and nuts) with one-fold no-weld construction, giving it extra corrosion protection. EZ-MAX, using a flat sealing system (product of Krausz or other), is sometimes mistakenly used for joining 2 pipes. This is unadvisable since a flat seal, as opposed to hydraulic fins, cannot absorb ground shifts which may cause it to leak.
TAPMAX For polyethylene and PVC piping
• TAPMAX is designed for installing an outlet on a pipe with no need for • • • •
electric fusion and no cutting of the pipe which would weaken it. TAPMAX opens and wraps around the pipe, and only afterwards the outlet is drilled through the TAPMAX (see picture). This system allows for quick installation at relatively low cost. The clamp is made of 316 stainless steel, for high durability against corrosion. Can be ordered in sizes from 110mm-170mm as standard, in a range of threaded or flanged outlets.
HYMAX
HYMAX •
Applications: Joining two pipes of equal diameter, but with different external circumferences (usually of different materials, such as connecting an asbestos pipe with a steel or PVC pipe).
To fully appreciate the unique innovation of the Krausz HYMAX, you only need to compare it with the old system:
The old system: The connector is made of 4 main parts: 1) Cone-shaped Orings 2) Main body 3) Cone-shaped gaskets 4) Galvanized bolts
Tightening the bolts causes the O-rings to tighten against the cone-shaped gasket and against the pipe, thereby “locking” the connector against the pipe. (This makes the connector unable to absorb vertical and axial shifts and vibrations caused by weather changes or mild earthquake.) The connector is typically very heavy, and the larger it is, the larger the number of bolts it requires. This requires extensive aligning and lengthy installation time.
The old system:
HYMAX from Krausz consists of:
• • • • •
O-rings Central body Double-layer detachable hydraulic gasket 2 stainless steel bolts (for large diameters – 4 bolts) HYMAX is oven-baked epoxy coated (or RiIsan per request)
HYMAX by Krausz Unique mode of operation 1.
The HYMAX detachable, double-layer, hydraulic gasket allows the detaching of one layer of the gasket which makes room for a pipe with larger outer circumference. In the case of a pipe with a small outer circumference, the gasket is not detached. The pipe is simply inserted and the screw tightened. The first level of sealing is accomplished by tightening the screw, which fastens the O-ring around the gasket, pressing it against the pipe. The second level of sealing is accomplished through the water pressure’s activation of the gasket hydraulics.
HYMAX by Krausz Unique mode of operation 2. The hydraulic fins allow for the absorption of vertical and axial ground movement resulting from weather changes or mild earthquakes. 3. HYMAX has one tightening screw in each O-ring (2 bolts for large diameters). This makes installation work far quicker and easier, with no need to tighten large numbers of bolts and alignments.
HYMAX by Krausz Unique mode of operation 4. A 12” HYMAX is capable of bridging between pipes of different materials with up to a 32mm difference in external circumferences. The HYMAX 14” bridging capability is unique for up to 54mm and represents a significant advantage for lower inventory requirements – one Krausz connector covers the entire range needed, as opposed to other manufacturers that require purchase of 2 to 3 connectors to cover the same range. 5. HYMAX is lightweight, requiring only one worker for easy installation, with no need for lifting heavy weights. Unique and innovative, Krausz multi-diameter products are in high demand in the international marketplace – we account for 30% of the American market for this product.
