MQ3-45

The GRUNDFOS MQ 3-45 is an all-in-one unit, designed for pumping clean water from break tanks and shallow wells, and for general pressure-boosting in private homes, farms, and irrigation.

The MQ is a complete, all-in-one unit, incorporating pump, motor, diaphragm tank, pressure and flow sensor, controller and non-return valve. The controller ensures that the pump starts automatically when water is consumed and stops automatically when the consumption ceases. In addition, the controller protects the pump in case of faults.

As it is self-priming, the MQ is able to pump water from a level below the pump.

Built-in protective functions If exposed to dry running or excessive temperature, for example in case of seizure or overload, the pump will stop automatically, thus preventing a motor burnout.
Due to its compact design, the pump does not take up much space and is easy to install. No space around the pump is required.

It has a rated flow of 2.5m3 /h at 3atm.
