Hardy water pumps for difficult conditions

Two water pumps, the Supermax borehole pump and surface pump, which were designed for use in areas with limited technical infrastructure and tested in harsh climatic conditions, are now commercially available.

Both pumps can be installed and serviced by people with very little technical knowledge, are easy to operate and have fewer wearing components than conventional pumps. They can be operated by hand, by a windmill, a diesel engine or an electric motor, according to designer and manufacturer Hans Carstens of Prima Engineering Services.The surface pump is designed to pump water from one reservoir to another situated up to 150 meter higher. A suction capacity of 2 meter deep is guaranteed. Limited tests are still necessary to prove suction of water up to 6 meter below surface.
As rust is the main enemy of most borehole pumps, the water-carrying pipes of the Supermax borehole pump are made of high-density poly-ethylene. The rods driving the pump run parallel to this pipe with the result that no seal is necessary where the pipe rises from the ground, eliminating the necessity for the force-head used in conventional pumping systems where water has to be raised higher than the surface driving mechanism.
All parts of both pumps’ cylinders are made of stainless steel.
The pumps cost between $120 and $175.
