Allied Pumps’ Bore Rising Main is an innovative system made from high quality rigid PVC and has been created to connect submersible pumps to site water distribution systems. The particular extrusion process the pipe is subjected to, as well as its physicochemical structure, allows the pipe to have exceptional resistance against high internal pressure and tensile loads.
Rising Pipe also offers extremely high impact strength. Laboratory and real life site tests have proved the product to be suited to the toughest applications with no pipes showing any signs of damage or stress during handling, installation and removal of pumps.
Allied Pumps’ Rising Pipe system has also been designed with ease of installation and transport in mind. The acme threads (male + male thread) at each pipe ends are supplied with a prearranged coupling. The inner part of the pipe coupling is equipped with two gaskets, which guarantee 100% sealing while operating at high pressures. The Rising Pipe coupling system also incorporates a locking ring which acts as a mechanical barrier to accidental loosening of the couplings due to vibrations or anomalous torsional stresses of the column. Connection of the pump to the rising main is via a heavy duty stainless steel coupling.
Rising Pipes have been designed to have totally smooth walls without any narrowing and/or corrosion. The design is also such that the pipe walls cannot be affected by subsurface stray current. Hydrodynamic tests that the pipes have undergone show exceptional hydraulic results with a hydraulic coefficient (k = 0.01), which ensures greater efficiency, lower pumping costs as well as a reduced water hammer effect due to a slower flow velocity (1/3 compared to metal piping).
Rising Pipes are also certified and suitable for transporting potable water and food liquids.
