The MQ is a compact water supply system consisting

of a pump, motor, pressure tank and controller
combined in an integral unit.

consumption ceases. The MQ is a low-noise pump
10
which can be installed both indoors and outdoors.

Typical applications:
14
•
Pressure boosting in storage tanks
(maximum inlet pressure 3 bar) and
•
water supply from wells (maximum suction lift
8 metres), e.g.
- in private homes
- in summer and weekend cottages
- on farms
- in market gardens and other large gardens.
The pump can be used for rain water and has been
approved for drinking water.
The maximum suction lift of the pump can be
determined from the diagram on page 261.
Example:
If the suction lift is 2.5 metres, the length of the
suction pipe must not exceed 24 metres.
