GRUNDFOS MQ - MQ 3-45

Compact, all-in-one unit for your home water supply

Easy to select

 

The Grundfos MQ is a compact pump and pressure 

boosting unit specially designed for home water supply.  

It is a reliable and very easy-to-operate unit that can 
be fitted almost anywhere.  The pump is self-priming, 

which means that it is capable of drawing water from 

a well depth of down to 8m.  As the MQ has a built-in 
pressure tank, you do not need a space-consuming tank.
 

The MQ pump is also ideal for boosting pressure 

from elevated or sub-terrain water storage tanks or from 
the water mains. 

Easy to install

 

The Grundfos MQ pump is easy to install.  The 

compact, horizontal design makes the pump easy to 

place even where space is limited.  The outlet pipe con-

nection can be angled up to 5” to fit existing pipework.

 

Due to the built-in pressure tank and integrated 

start/stop features there is no need for adjusting a sepa-
rate pressure switch.

 

The MQ is water-cooled and therefore has no noisy 

cooling fan.  As it is self-priming, it is not necessary to 

allow free space around the pump for priming.

Easy to operate

 

Operation of the Grundfos MQ pump is simple and 

easy.  Once installed it needs only a push on the “On” 
button to provide many years of reliable service.  The 
actual settings are clearly indicated by indicator lights 
on the user-friendly control panel.

 

The MQ pump has a small built-in pressure tank, 

sufficient to ensure that water is readily available from 

the tap.  The pump starts automatically as soon as the 
tap is opened and no loss of pressure is felt.

Unique user benefits

 

The Grundfos MQ “anti-cycling” feature prevents 

the pump from continuously starting and stopping in the 
event of a dripping tap or minor leak in the system.

 

The MQ pump has built-in dry-running protection.  

If for any reason water is not available, the pump auto

-

matically switches off.  It will subsequently attempt to 

re-start every half hour for up to 24 hours until water is 
again available.

 

The pump also has a built-in thermal protection.  If 

it overheats, the pump will stop immediately.  After a 
30-minute cooling-down period, the pump will automati

-

cally restart.

Corrosion-free

 

The Grundfos MQ pump is built for long-term, 

trouble-free operation.  It is made of weatherproof, 
corrosion-resistant materials and can, if necessary, be 

placed outdoors.
 

A drain plug enables easy draining of the pump.  

This is especially convenient if the pump is installed in 

a front-risk location such as a holiday cottage.  The MQ 

pump is suitable for rainwater and will not contaminate 
drinking water.

User-friendly control panel
The Grundfos MQ features an easy-to-use control panel 

with indicator lights for indication of
• pump on
• auto-reset
• alarm (dry-running or overheating)

In the even of dry-running, the pump will stop and 

afterwards attempt to restart automatically.  Restarting 

can also be done manually.  If required, the auto-reset 

function can be disabled.
