3. 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.
