Dry run protectionThe built-in controller protects the pump in case of loss of water supply (i.e. dry running) and motor overheating.

Self-priming pumpThe 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.

Silent operationThanks to its hydraulic design and internal cooling, the pump is extremely silent, which makes it ideal for indoor as well as outdoor use.
