Grundfos SQFlex 8A-5 Solar Submersible Pump
The Grundfos SQFlex 8A-5 solar submersible 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.
The solar panels and wind turbines of the pumps of the SQFlex range allow them to adapt to the existing climatic conditions in any place.
The surplus generated energy can be stored in a reserve battery system so that it can be used when energy can not be extracted from natural sources
