The Grundfos SQ 3" submersible pumps offer a wide performance range, making it easy to find a model that will suit your individual requirements.

The SQ is a compact, 3" multistage centrifugal pump that can be installed in a borehole no larger than the pump itself. With their built-in electronics, SQ pumps are very easy to install and operate. They guarantee a reliable water supply at all times.

Equipped with permanent magnet motors, these flexible and compact pumps offer excellent efficiency levels and will supply pump heads up to 200 m.

If the SQ pump is connected to the Grundfos CU 301 control box, forming the SQE, it enables the creation of a constant pressure water supply.
