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

Planning guide

Pressure reducer

Excessively high or strongly fluctuating inlet pressure requires the installation of a pressure reducer to maintain a constant minimum inlet pressure level. The maximum permissible fluctuation of the inlet pressure is 1.0 bar.

Volume flow

Up to 8 m3/h (111 l/s) system configuration according to DIN 1988 (EN 806); with standby pump up to 16 m3/h (133 l/s), with the standby pumps used for the peak-load operation.

Inlet pressure

The maximum inlet pressure (see Technical data) is to be observed for the system configuration. The maximum inlet pressure is calculated from the maximum unit working pressure minus the maximum pump delivery head at Q = 0.

Low-water cut-out switchgear (WMS)

According to DIN 1988 (EN 806), the installation of a low-water cut-out switchgear is required if the pressure boosting systems are connected directly to a public mains power supply; this prevents the inlet pressure in the mains supply line from dropping to values below 1.0 bar.


The overall system meets the requirements of the following standards and guidelines:

  • EN2006/42/EC
  • EN2004/108/EC
  • CEM 2004/108/EC

The requirements of the standard EN 806 and those of water supply companies must be met with regard to the electrical components.

The requirements of DIN 1988 (EN 806) are to be observed whenever the pressure boosting system is used or operated.

KSB - HGM-RO High-pressure pumps for reverse osmosis systems



KSB-HGM-RO high-pressure pump – reliable drinking water treatment in reverse osmosis systems



Drinking water production in RO systems requires a high-pressure pump of top reliability which provides continuously economical operation. KSB responds to this need with an ideal solution: the HGM-RO high-pressure pump.







High-pressure pumps  HGM-RO High-pressure pumps for reverse osmosis systems need to be able to handle the harsh conditions which prevail in seawater desalination plants.



KSB has opted for radially split high-pressure pumps.

Their radially split design makes HGM-RO high-pressure pumps particularly robust, enabling them to cope with the extreme conditions of drinking water treatment in seawater desalination.




Benefits of using KSB’s radially split high-pressure pumps in reverse osmosis systems:

HGM-RO-Radially-split-designMinimum energy input, low operating costs

Excellent NPSH value thanks to axial inflow with suction stage impeller. Continuously high efficiencies.


Compact design

Internal, product-lubricated plain bearings with a short bearing span ensure smooth running and therefore high pump availability and reliability as well as a long service life of wear parts.


Corrosion-resistant design

The HGM-RO high-pressure pump is made of duplex or super duplex stainless steels. Its corrosion-resistant design (e.g. dry shaft) translates into a long service life.


Low monitoring requirements

There is no need for an additional lubrication system, and the pump does not require any vibration or bearing temperature monitoring. This saves both initial and operating costs for the pump set.

Minimum maintenance costs

Because of its axial inlet, the HGM-RO high-pressure pump has just one mechanical seal, which minimises spare parts costs. The ring section design ensures top reliability in the extreme conditions of reverse osmosis systems. No lubrication systems are required. The mechanical seal is easy to replace.

Reduced construction costs

The pump’s compact design, low weight and smooth running lower the requirements to be met by the foundation. Flexible connection branches facilitate connection to the system piping.


Easier to install and dismantle than axially split pumps

The pump can be dismantled and reassembled from either side. The wear parts are easily accessible.
