The Grundfos’ MQ pump is compact and extremely
easy to install. The pressure switch and tank are
already built into the MQ. Furthermore, it is self-
priming and water-cooled with a very low noise level.
The outlet pipe connection can be angled up to 5° to
fit your existing pipe-work.
Grundfos’ MQ pump is simple and easy to operate.
The settings are clearly indicated on the user-friendly
control panel with indicator lights for Pump on/off,
auto reset, and an alarm indicating dry running or
overheating.
Grundfos MQ is built for trouble-free operation. It’s
construction from corrosion-resistant materials
means it can be used for clean water. The anti-cycling
feature prevents the pump from repeatedly starting
and stopping in the event of a dripping tap or a minor
leak. If there is no water available, the pump will stop
to protect itself and restart automatically when
water is available again.
