Grundfos SQFlex Solar & Wind Powered Pumps

The Grundfos SQFlex range offers an alternative solution for powering submersible water pumps using sun and/or wind energy via solar panels or turbines.

Grundfos SQFlex solar & wind pumps are ideally suited for use in remote locations where other sources of electrical power are absent or unreliable.

sqflexThe SQFlex System

Solar or wind powered pumps available from Grundfos are driven directly from the energy obtained from solar panels or wind turbines. They operate on either 30-300 V DC (Direct Current) or 90-240 V AC (Alternating current) and require no invertor.  This is possible due to the variable speed capacity of the pumps. Their unique design enables them to have a back up power supply from a generator, battery bank, utility grid or a combination of these sources

The SQF submersible pump is very flexible regarding its energy supply and performance and has been designed for intermittent or continuous operation. The system can be combined and adapted to any need according to the conditions on site.

International Projects

The SQFlex solar powered pumps are particularly popular in southern Europe, Asia, the Middle East and Africa. Because the system produces its own electricity via the sun/wind they are beneficial to remote villages or buildings not connected to a main power supply or where the power supply is unreliable. No additional fuels are needed to power the submersible pump, therefore, after initial installation the cost of running the system and producing the power relative low.
