MQ Successor can connect via Bluetooth.

The MQ Successor is a self-priming, multistage pump, that incorporates all the components of a pressure booster into a compact composite enclosure.

As it is self-priming, the MQ Successor an pump water from a level below the pump. Provided it is filled with water, the pump can lift water from a depth of 26 feet in less than 5 minutes. This facilitates easy 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.

MQ Successor can communicate with Grundfos GO app via built in Bluetooth, which enables detailed pump monitoring and high customization options, making this pump a good fit for every application.

MQ Successor incorporates advanced protection features such as:

  • Dry running protection that will automatically stop the pump in case of water shortage
  • Cycling protection which will prevent pump starting frequently in case of minor leakages in installation
  • Max runtime protection can stop the pump after a desired period of continuous operation, preventing potential damage due flooding in case of pipe breakages.

The pump has a built-in motor protection that will stop the pump if exposed to excessive temperature due to high ambient temperature, in case of seizure or overload, thus preventing a motor burnout.

With Grundfos GO, you can easily setup MQ Successor as a Twin booster system, operating as duty/stand by as well as duty/assist. It is also possible to add external input control and schedule a pump operation via calendar function.

MQ Successor requires no maintenance, but it is recommended to keep the pump clean. Check the non-return valves, and keep the ventilation holes free of dust.

The MQ Successor is a fully integrated, all-in-one, self-priming, compact waterworks designed for pressure boosting in domestic and light-commercial applications, such as garden irrigation or pressure boosting to one and two family houses and apartments.
