    Properties:



    Single-stage close-coupled pumps according to EN 733 with MGE motor


    The pump is directly connected to a fan-cooled permanent magnet synchronous motor. For speed control, the motor has a frequency converter and PI controller housed in the motor's terminal box. The electronic speed control enables continuous adjustment of the motor speed and thus the pump performance to the current demand.
