The Amarex/KRT series is coupled with energy-efficient motors which meet the new European IE3 Premium Efficiency requirements for standard motors up to a drive rating of 150 kW.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, KSB says.Dry-installed pumps up to 45 kW can also be driven by the KSB-developed “SuPremE” motor, cutting the losses of the IE3 motors by another 15%. The ISH show takes place from 15-19th March 2011 in Frankfurt, Germany.
