Features and benefits
• Complete system
The MQ is a complete, all-in-one unit, incorporating
pump, motor, diaphragm tank, pressure and flow sensor,
controller and check valve.
The controller ensures that the pump starts auto matically
when water is consumed and stops auto matically when
the consumption ceases. In addition, the controller
protects the pump in case of faults.
• Installation
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 26 ft (8 m) in
less than 5 minutes. This facilitates installa tion and start-
up of the pump and provides more re liable 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, excessive temperature, or any
overload condition 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 de activated.
• Low noise level
Thanks to its hydraulic design and internal cooling, the
pump is very quiet, which makes it suitable for many
applications.
• Pressure tank
The built-in pressure tank reduces the number of starts
and stops in case of leakages in the pipe sys tem, causing
less wear on the pump.
• Maintenance
No maintenance of the pump is required.
