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 out-
door 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.
