Grundfos Solar PumpsThe SQFlex family is an environmentally-friendly water supply system. SQFlex pumps are fitted with a permanent magnet motor which enables the efficient use of energy from a wide range of supply options. The pump system offers the perfect water mote areas where water is scarce and the power supply is non-existent or unreliable.

Very flexible as to its energy supply and performance, the SQFlex system can be combined and adapted to any need according to the conditions on the installation site. A battery backup system can store the extra energy generated and take over when the primary energy source is not available.

SQFlex is more than just a pump – it's a complete system. Thanks to its built-in electronics, the pump is compatible with both DC and AC power supply without requiring an external inverter.

The complete range consists of eleven different pump sizes: Five helical rotor pumps for applications where a high head is required, and six centrifugal pumps for applications where a greater flow rate is necessary.
