Underwater solar water pump Grundfos SQFlex 0.6-2

Submersible solar pump Grundfos SQFlex 0.6-3
The Grundfos SQFlex 0.6-3 submersible solar pump models are an environmentally responsible solution for water supply.

The pumps in the SQFlex range incorporate a permanent magnet motor that allows the efficient use of energy from natural sources. This pumping system is an ideal solution for the supply of water in areas of difficult access in which it is scarce and the electricity supply is nonexistent or unreliable.
