The MQ is a Home water pump for cisterns and shallow wells. It's a complete, self-priming 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. If water runs out, the pump will automatically stop to protect itself.
