Get a reliable water supply with the SQ submersible pump

The Grundfos SQ is a compact 3” multistage centrifugal pump, which can be installed in boreholes that are 3” or larger. Featuring built-in electronics, it is simple to install and operate and guarantees a reliable water supply at all times. The SQ submersible groundwater pumps are equipped with permanent magnet motors and can supply pump heads up to 200 m.

The single high-speed SQ submersible groundwater pump is suitable for both continuous and intermittent operation for a variety of applications, including domestic water supply, small water works, irrigation and groundwater lowering.

SQ is big in performance and small in size

Thanks to its high-speed permanent magnet motor, the SQ pump offers high performance in relation to its compact design.

With soft start of your pump you eliminate​:

  • Abrupt interruption of power supply for other electric appliances​
  • Liquid hammer effect in water installations​
  • Shifting of pump in the well​

See how with the SQ pump​.

Dry-running and overload protection safeguards against liquid absence and unstable motor supplies.

Large voltage fluctuations in the network are among the most common reasons for pumps to break down. The SQ pump has in-build protection from this. See how.
