GRUNDFOS MQ PUMPS
Compact, all-in-one unit, designed for home water supply systems
The Grundfos MQ is a compact all-in-one pressure
boosting unit, designed for domestic water sypply and
other boosting or lift applications. The MQ is a compact and reliable, east-to-install pump, with many
standard features.
The MQ is a self-priming multistage centrifugal pump. It
self-primes from a well depth of down to 25 feet within a
maximum time of 5 minutes. The MQ pump is also ideal
for pressure boosting from water storage tanks or from
city water supply (maximum 45 psi inlet pressure).
The MQ pump is built for long life, trouble-free operation. It is made from weatherproof, corrosion-resistant
materials and can be placed outdoors.
EASY TO SELECT
The Grundfos MQ makes it easy to select the right pump.
The MQ is an all-in-one unit with two models to choose
from. There is no need to worry about a separate pressure tank, pressure switch, electrical connections, fittings,
or any other separate items. With MQ it is literally a
matter of connect the power and turn on the pump.
Installation of an MQ pump is simple and can be done in
a matter of minutes, which gives you more time to relax.
The Grundfos MQ features an east-touse control panel with indicator lights
for indication of:
• pump on
• auto reset
• alarm (dry-running or overheating).
In the event of dry-run, 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 as well.
EASY TO INSTALL
The MQ pump is east to install. The discharge connection can move up to 5° to fit existing
pipework, and the compact design makes the pump easy to place even where space is limited.

EASY TO OPERATE
Operating the MQ pump is simple and easy. The actual
settings are clearly indicated by light-diodes on the userfriendly control panel.
The MQ pump has a small built-in pressure tank to
ensure that water is readily available from
the tap. When water is required, the
pump automatically starts and no loss
of pressure will be felt. It also features
an built-in check valve.
UNIQUE USER BENEFITS
“Whisper quiet operation,” the MQ is
specially designed for use in domestic applications where low noise is a major consideration. The pump
is cooled by the pumped water which eliminated the need for a noisy cooling fan. Because the
pump is self-cooling, you don’t need to have free space around the pump for cooling purposes.
The MQ “anti-cycling” feature prevents the pump from continuously starting and stopping when
you have a dripping tap or minor leak in the system.
PROTECTIVE FEATURES
The MQ pump has built-in dry-run protection. If the pump runs dry, the pump automatically stops. It will
then attempt to restart every half hour for a maximum of 24 hours until water is available from the source.
If more than 24 hours pass without water, the pump must be restarted manually. The auto reset
function can also be disabled.
The MQ pump also has built-in thermal protection. If the pump overheats it immediately stops.
After a 30-minute cooling-down period, the pump will automatically restart.
The MQ has an easy accessible priming plug for filling the pump with water before start. It also
has a drain plug to prevent the pump from freezing.
