The MQ is a complete all-in-one unit incorporating pump, motor, diaphragm tank, pressure and flow sensor, controller and non-return valve that boosts your cold water supply to sinks, wash hand basins, domestic hot water cylinders and in turn showers. The built-in 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. This is a fixed speed pump.
Easy Installation and Operation
Due to its compact design, the Grundfos MQ 3-45 pump takes up minimum space and is easy to install. Very liitle space is required around the pump. The MQ 3-45 pump features a user-friendly control panel with an ON/OFF button and a set of indicator lights that identify the operational state of the pump
Self-priming and Automatic Protective Functions
A self-priming pump, the MQ 3-45 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. If exposed to dry running or excessive temperature, e.g. in case of seizure or overload, the MQ3-45 pump will stop automatically, preventing a motor burnout.
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.
