solar water pump systems

Have water but no power !

Water where you need it but no power? No problem
Lorentz helical rotor solar powered submersible water pumps are high quality products designed for drinking water supplies, livestock watering and smaller irrigation applications.
The Lorentz range have been specifically designed to deliver water efficiently using only solar power,  which allows pumping from deep well bores, dams, streams and tanks from anywhere that receives sunshine with the ability of pumping up to 350mtrs head with no pollution.
Each pumping system is made up of a helical rotor pump head, brushless 3ph pump motor and a controller, this modular concept keeps all the electronics above ground providing simple servicing, ease of access and a low cost of owner ship.

Lorentz Solar powered helical rotor pumps deliver water economically, cleanly and reliably, ANYWHERE.

Lorentz submersible pumps are the ideal solution for rural areas with no power, fitting down most standard 4" and 6" bores replacing expensive mains power pumps.

No running costs, harness the free power of the sun to pump water for stock, irrigation, drinking water.

Long life pump head, sealed three phase brushless motor, MPPT Run direct off solar panels or incorporate batteries for longer running each day.
