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.
