Amarex KRT with highly efficient submersible motors
With highly efficient IE3* submersible motors the pumps of the Amarex KRT® series are a true innovation on the market. KSB’s extremely energy-efficient motors can be integrated into pump stations as standard. The pump sets can be supplied with or without explosion protection
KSB’s in-house development work has enabled these pump sets to be mechanically and electrically optimised for the special requirements of waste water transport. The Amarex KRT motors’ electrical and magnetic design fulfils the requirements of the IE3* efficiency class up to a drive rating of 850 KW.
Combining these motors with a wide range of hydraulic systems for handling waste water enables KSB to provide pump sets offering superb efficiency and dependable operation for every application. Save energy effectively
Design
Vertical, single-stage submersible motor pump in close-coupled design, various impeller types, for wet or dry installation, stationary and transportable version. Design to ATEX.
Applications
Handling of all types of abrasive or aggressive waste water in water and waste water engineering as well as industry, especially untreated sewage containing long fibres and solid substances, fluids containing gas / air, as well as raw, activated and digested sludge; sea water desalination.
Pump sets of installation types P and S
are designed for continuously submerged operation. The motor is cooled by the fluid
handled on the motor surface. Operation with the motor outside the fluid handled is
possible for short periods.
Pump sets of installation type K
are suitable for continuous operation with the motor outside the fluid. Cooling is
effected by means of air convection.
