Highly efficient waste water pumps with energy-efficient IE2 and IE3 motors

At the ISH 2011 KSB presented its Amarex/KRT waste water pumps. Their energy-efficient motors comply with IE2 or IE3 classification to EN 60034-30 based on EC regulation 640/2009 for standardised motors.

Amarex KRT with IE3 motor

Developed in-house, KSB's IE3 motors are perfectly matched to the mechanical and electrical requirements of waste water pump hydraulics.Owing to their optimised electrical and magnetic design, our Amarex/KRT waste water pumps fulfil the requirements of efficiency classes IE2 and IE3 up to a drive rating of 150 kW.Another plus of IE3 motors:They are available both in explosion-proof and in a non-explosion-proof design.
