Groundwater Intake Pumps
For Renewable Energies

Grundfos SQFlex

The Grundfos SQFlex family is an environmentally-friendly water supply solution.

Grundfos SQFlex pumps are fitted with a permanent magnet motor which enables the efficient
use of energy from nature.

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 Grundfos 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 energy from nature is not available.

Grundfos SQFlex is more than just a pump – it’s a complete intelligent 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 ten different pump sizes:

  • ✔︎ 4 progressive cavity pumps for applications where a high head is required
  • ✔︎ 6 centrifugal pumps for applications where a greater flow rate is necessary
