Lorentz PS4000HR - Submersible Solar Pump - 450m Head

Special Order





The PS4000-HR series is a powerful, maintenance-free solar bore pump with a flow rate of up to 2,500 litres per hour. The pump system is typically powered by 2-6 solar panels (e.g. Trina Honey Module). Designed for min. 100mm (4 inch) wells.

The helical rotor pump (with brushless DC motor) comes with a UL approved, programmable controller (IP65), housing all electronics and a data module with Bluetooth connection.

A PS4000 helical pump delivers about 2,500 litres per hour @ 4 metres head (or 350L @ 450m). Read more about Lorentz Centrifugal Solar Pumps or download the spec sheet (downloads tab).
