Lorentz PS1800HR - Submersible Solar Pump - 250m Head

Special Order





The PS1800-HR series is a powerful, maintenance-free solar bore pump with a flow rate of up to 3,900 litres per hour. The pump system is typically powered by 2-4 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 (IP68), housing all electronics and a data module with Bluetooth connection.

A PS1800 helical pump delivers about 3,900 litres per hour @ 20 metres head (or 850L @ 250m). Read more about Lorentz Centrifugal Solar Pumps or download the spec sheet (downloads tab).
