If your pump is equipped with an IEC norm motor as a drive, there is a connection for the
shaft bearing between the pump and the motor.
•
Version 1: Bearing retainer with 1 ball bearing
•
Version 2: Intermediate lantern with plug-in shaft and without ball bearing
•
Version 3: Bearing pedestal with 2 ball bearings and coupling
The bearings are closed and have permanent grease lubrication. The coupling is designed

Three different versions of connection are installed in the pumps.
