The SQFlex family is an environmental friendly water supply solution. SQFlex uses a permanent magnet motor which enables an efficient use of the natural energy. The pump system offers the perfect water supply solution in remote areas where water is scarce and the power supply is non-existent or unreliable.

The SQFlex solar panels and wind turbines adapt to the characteristic weather profile of any given area. A battery backup system can store the extra energy generated and take over when the natural energy are scarce.

SQFlex is more than just a pump – it’s a complete system with intelligence. And because of the built-in electronics the pump is compatible with both DC and AC power supply without an external inverter.

The complete range consists of 10 different pump sizes: 4 helical rotor pumps for applications where a high head is required and 6 centrifugal pumps for applications where a higher flow is necessary.
