KSB Group Amarex/KRT wastewater pump

At the ISH trade fair 2011, KSB Group presented its Amarex/KRT wastewater pump series coupled with energy-efficient motors which meet the new European IE3 Premium Efficiency requirements for standard motors. 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 wastewater 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, which is claimed to cut the losses of the highly efficient IE3 motors by another 15%. These motors provide operators with a technology which already surpasses the upcoming legal efficiency requirements.
