Highly efficient waste water pumps
At the ISH trade fair 2011, KSB Aktiengesellschaft, Frankenthal, Germany, will present its Amarex/KRT waste water pump series coupled with energy-efficient motors which meet the new European IE3 Premium Efficiency requirements for standard motors.
These pump sets can be supplied with or without explosion protection. Whether operated at rated or low flow conditions, their efficiency exceeds that of standard submersible motors. And they are just as robust!
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.
