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 450 m3/hour. Each system consists of a pump, pump motor and a controller. This modular concept keeps all electronics above ground providing, simple servicing, ease of access and a low cost of ownership. LORENTZ submersible pumps are deployed in irrigation systems, drinking water provision, water treatment and livestock.

Surface Pumps

LORENTZ surface pump systems are used as circulating pumps for swimming pools and any other filtration systems. LORENTZ surface solar pumps are, also used as booster pumps for industrial applications.The new PS CS-F surface range uses our market leading PS 600 / PS 1800 / PS 4000 controllers and ECDRIVE drives coupled to a surface pump end. The pumps are being introduced to meet the market need for high flow pumps typically in irrigation applications with flow rates up to 59 m3/h. This further extends our product portfolio and continues to ensure LORENTZ is the world’s number one solar water pumping company.

Flood Irrigation

The water is lifted from canals, rivers or wells; afterwards the water flow is done by gravity, so called “gravity irrigation systems”. For border irrigation, used mainly for paddy rice production, the water is poured into a basin until is reaches a certain height related to the plant development of e.g. the rice seedlings. The young plants (roots) are complete grown in stagnated water. Periodically the irrigation is repeated until the crops are mature and ready for the dry harvest.
