Highly efficient wastewater pumps with energy-efficient IE2 and IE3 motors
At the ISH 2011 KSB presented its Amarex/KRT wastewater pumps. The energy-efficient motors comply with IE2 or IE3 classification to EN 60034-30 based on EC regulation 640/2009 for standardised motors.
Developed in-house, KSB's IE3 motors are perfectly matched to the mechanical and electrical requirements of wastewater pump hydraulics.
Owing to their optimised electrical and magnetic design, our Amarex/KRT wastewater 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.
