Solar pump for floods and droughts

A solar powered, submersible pump has been developed for regions where both droughts and floods are commonplace and where electricity is not available, like farms, game parks, rural schools or clinics.
Called the Watermax, the pump can be run on a “float” switch, which automatically controls the water level in a dam or storge tank.

Called the Watermax, the pump can be run on a “float” switch, which automatically controls the water level in a dam or storge tank. Unlike most pumps, the motor does not burn out should the pump run dry, and no manual priming is necessary should this occur.
Another unique feature is that the pump is moveable and can be rotated between boreholes and/or dams in different locations.The pump’s simplicity enables the owner to take responsibility for maintenance and parts are available at the various global distributors at low prices. For example the diaphragm costs about $12 and takes only ten minutes to change. This needs to be done once every 18 – 24 months. Brushes and bearings are to be changed no more often than every four to six years, if necessary. These two processes encompass the total service needs of the pump.
A further advantage for developing countries where the power supply is limited and often unreliable is that the pump runs on solar power. No batteries or inverters are used, increasing the reliability of the system.
The pump is equipped with an equalizing diaphragm, which compensates for submergence pressure, allowing the pump to work from early in the morning until late in the evening. It is made of high quality stainless steel, bronze and aluminium and is thus rust-free. Each pump is insulated for protection against lightning and comes with a manual, service guide a two-year guarantee.
The pump was developed in South Africa in 1989, and was placed among the top 100 products of the Standard Bank Science and Technology Award. It has been approved and recommended by Siemens, Germany. Manufactured in South Africa, the pump is exported to other African countries, Australia, America and Spain. More than 6,000 units have been installed to date. The units are available in a range of sizes, varying in capacity from 1,000 litres/day to 16,000 litres/day. Complete kits (including solar panels) cost between $1,070 – $4,4000 depending on the size and model required.
