1. Introduction
The MQ is a low-noise water supply system
consisting of pump, motor, pressure tank and
controller combined into one compact unit. The
system is suitable for both indoor and outdoor use.
The self-priming pump starts automatically when
water is consumed in the installation and stops when
consumption ceases. The internal, built-in non-return
valve prevents backflow during priming and
operation.
The MQ pump incorporates overtemperature and
dry-running protection as well as a user-friendly
control panel.
The built-in pressure tank reduces the number of
starts and stops in case of leakage in the installation.
2. Items supplied
The MQ packaging contains these items:
• MQ water supply system with built-in non-return
valve
• non-return inlet valve in plastic bag
• installation and operating instructions.

4. Applications
The MQ water supply system is designed for these
typical applications:
• water pressure boosting
(maximum inlet pressure: 40 psi)
• water supply from wells (maximum suction lift:
25 ft), for example
- in private homes
- on farms
- in market gardens and other large gardens.
The pump is suitable for rain water.
4.1 Pumped liquids
Thin, clean, non-aggressive liquids, not containing
solid particles or fibres.
