MQ series
PREMIUM GRADE SUBMERSIBLE SEWAGE PUMPS
SERIES MQ
The MQ-series of the TSURUMI AVANT brand adds an IE3 premium efficiency motor to the premium grade of submersible sewage pumps that Tsurumi makes. With this new series, overall efficiency and energy-savings have been taken to new heights by pursuing greater efficiency in both the pump and motor.
Moreover, to ensure users get what they are looking for, the MQ-series offers 5 types of impellers (Open Channel, Chopper, Vortex, Grinder and High Head) and super wide ranges of specifications featuring 50 to 500 mm discharge bore diameters and 1.1 to 355 kW motor output specifications. Plus, pump installation can be chosen between a WET version that submerges the pump in water or a DRY version that installs the pump indoors or outside the tank using the original closed loop cooling system with internal recirculation.
Furthermore, MQ-series pumps accordance with IECEx explosion-proof specifications, and can be used in dry pits and other sites.
