PS Helical Rotor Solar Pump Systems Submersible Pump Systems for 4” and 6” Wells LORENTZ PS helical rotor pumps are high quality products designed for drinking water supply, livestock watering and smaller irrigation applications. PS helical rotor pump systems deliver water economically, cleanly and reliably, anywhere. The LORENTZ PS range of DC powered helical rotor pumps have been designed specifically to pump water efficiently using solar power. The helical rotor pump is simple, efficient and reliable, pumping water with very low levels of solar power from up to 450 m below the ground. Long life expectancy and proven in service record Designed for use in remote and harsh conditions Smart modular design for simple and cost effective servicing and repair Water filled motors for reliability and to avoid oil contamination Fast and simple installation Cost effective spare parts philosophy Very strong ROI against diesel powered pumping Large range of pumps to closely match each application and optimise efficiency Engineered in Germany Water temperature specific variants to provide the most efficient outputs High quality non corrodible materials used throughout Cast stainless steel components Solar direct connect with AC connection options MPPT technology to maximise power use from PV modules ECDRIVE DC brushless motors, designed for solar, with over 90 % efficiency Optional data logger pump system max. total dynamic head (TDH) v130701 photo credits: LORENTZ archive, Shutterstock/Tyler Olson, Shutterstock/africa924 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. open circuit voltage (Voc) nominal voltage solar operation: battery operation: nominal voltage *) PV modules at standard test condition: AM = 1.5, E = 1,000 W/m², cell temperature: 25 °C To nd out more visit www.lorentz.de BERNT LORENTZ GmbH & Co.
