3/4 HP 110-120V Booster Pump

The MQ is a complete, all-in-one unit, incorporating pump, motor, diaphragm tank, pressure
and flow sensor, controller and non-return valve.
The controller ensures that the pump starts automatically when water is consumed and stops
automatically when the consumption ceases. In addition, the controller protects the pump in
case of faults.

Due to its compact design, the pump does not take up much space and is easy to install. No
space around the pump is required.

Simple operation
The pump features a user-friendly control panel with ON/OFF button and indicator lights for
indication of the operational state of the pump.

Self-priming pump
As it is self-priming, the MQ is able to pump water from a level below the pump. Provided it is
filled with water, the pump is able to lift water from a depth of 8 m in less than 5 minutes. This
facilitates installation and start-up of the pump and provides more reliable water supply in
installations where there is a risk of dry running and leakages in suction hose or pipes.

Built-in protective functions
If exposed to dry running or excessive temperature, for example in case of seizure or overload,
the pump will stop automatically, thus preventing a motor burnout.

Automatic reset
The pump features an automatic reset function. In case of dry running or similar alarm, the
pump will stop. Restarting will be attempted every 30 minutes for a period of 24 hours. The
reset function can be deactivated.

Low noise level
Thanks to its hydraulic design and internal cooling, the pump is extremely low-noise, which
makes it suitable for indoor as well as outdoor use.

Pressure tank
The built-in pressure tank reduces the number of starts and stops in case of leakages in the
pipe system, causing less wear on the pump.

No maintenance of the pump is required.
