Lorentz PS4000 C-SJ8-15 Solar Borehole Pump

SKU SPP-L-PS4000-C-SJ8-15

LORENTZ PS centrifugal pumps are high quality products designed for higher flow drinking water supply, livestock watering, pond management and irrigation applications. PS centrifugal pumps provide large volumes of water economically, without pollution, anywhere.

The LORENTZ PS range of DC powered centrifugal pumps have been designed specifically to pump larger volumes of water efficiently using solar power. These highly efficient pumps can achieve flow rates of 79 m3/hour.

Each system consists of a pump, pumpmotor and a controller. This modular concept keeps all electronics above ground providing, simple servicing, ease of access and a low cost of ownership.
