LORENTZ's surface variants of the PS2 platform handle water transfer, pond management, irrigation and pressure boosting on solar power. Built on the same PS2-150 to PS2-4000 controllers (150 W to 4 kW), the family pairs air-cooled ECDRIVE brushless DC motors (over 90% efficiency) with a positive-displacement pump on the PS2-150 Boost for pressure duties and centrifugal CS-F pumps for volume duties.

LORENTZ's official datasheet publishes ratings in imperial units: the PS2-150 Boost reaches 500 ft of total dynamic head, while the PS2-4000 CS-F delivers up to 15,600 US gallons per hour. Solar-direct connection with AC options, MPPT, an inbuilt data logger with wireless access and PumpScanner app configuration complete the German-engineered package.
