Grundfos MQ self-priming multistage pump

Grundfos MQ self-priming multistage pump

…much more compact

The Grundfos MQ is a compact all-in-one pressure boosting unit,
designed for domestic water supply and other boosting or lift
applications. The MQ is a compact and reliable, easy-to-install
pump, with many standard features.

The MQ pump is ideal for pressure boosting from water storage
tanks or from city water supply (maximum 45 psi inlet pressure).
The MQ is also a self-priming multistage centrifugal pump. It can
selfprime from a well depth of down to 26 feet within a
maximum time of 5 minutes.*

* For detailed suction lift performance characteristics, refer to
the MQ product guide




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 selfpriming
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
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

The installation design options provide the flexibility needed to cover many needs. Applications include:

  • Construction sites
  • Excavations
  • Tunnels
  • Fish ponds
  • Drainage pits.


Operating conditions

The DPK pump range is suitable for two operating
• continuous, submerged operation, S1, with min.
liquid level above the pump
• intermittent operation, S3, with the pump partly
