Description

This is the Grundfos 6 SQF-3 SQFlex Submersible Solar Pump. One of Grundfos’ premier SQFlex line of submersible pumps. This pump provides the basis for a complete off-grid water supply system that incorporates the best engineering. Built with flexibility in mind, the 6 SQF-3 pump is able to run efficiently from either AC or DC power, and incorporates a built-in MPPT controller and soft-start. This model is a helical rotor pump, ideal when up to 250m (820′) of lift is required, and up to 24 L/min (5.8 Gal/min).

When the solar resource is unreliable, the Grundfos SQFlex pumps can be integrated with battery back-up systems.
