KSB has developed these motors and manufactures them, making sure they are perfectly matched to the mechanical and electrical requirements of waste water pump hydraulics.

By optimising the electric and magnetic design, the pump manufacturer has already fulfilled the requirements of efficiency class IE3 for its KRT series up to a drive rating of 150 kW.

Dry-installed pumps up to 45 kW can also be driven by the KSB-developed “SuPremE” motor, cutting the losses of the highly efficient IE3 motors by another 15 percent. These motors provide operators with a technology which, already today, more than surpasses the upcoming legal efficiency requirements. Following are some major features of the pump.

1. Optimum hydraulic and energy efficiency due to variable hydraulic systems offering the right impeller for every fluid.
2. Non-clogging low-maintenance design and large free passages substantially reduce clogging risk and maintenance (inspection hole provided on pumps with DN 100 and above).
3. Safety, Absolutely water-tight resin-sealed cable entries prevent any water from entering the motor – even in the event of a damaged cable.
4. Reliability due to two bi-rotational mechanical seals and rolling element bearings sealed for life.
5. Monitoring, Sensors monitor the motor temperature and prevent overheating. Moisture sensors signal any ingress of moisture into the motor.
6. Long service life. The shaft is made of corrosionproof stainless steel.All wetted fasteners, too, are made of stainless steel.

The motors are available with power ratings of:

5,0 – 19 kW 2-pole

4,0 – 150 kW 4-pole

4,8 – 132 kW 6-pole

in the following variants:

400 V 50 Hz, non-explosionproof (U)

400 V 50 Hz,explosion-proof EEx d II BT4 (Y)

460 V 60 Hz,non-explosionproof (U)

460 V 60 Hz,explosion-proof FM Class I, Division I,Group C & D (X)
