2. General description
The MQ is a compact water supply system consisting
of a pump, motor, pressure tank and controller
combined in an integral unit.
The pump starts automatically when water is
consumed in the installation and stops when the
consumption ceases. The MQ is a low-noise pump
which can be installed both indoors and outdoors.
The pump is self-priming and has a non-return valve
incorporated in the suction port. See fig. 1.
The pump features a user-friendly control panel.
The pressure tank incorporated in the pump reduces
the number of starts and stops in case of leakage in
the installation.
The MQ pump has built-in overtemperature and
dry-running protection.
2.1 Applications
Typical applications:
• Water 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 houses 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 237.
Example:
If the suction lift is 2.5 metres, the length of the
suction pipe must not exceed 24 metres.
