Shaft seal

The mechanical shaft seal is self-adjusting and has 
wear-resistant seal rings which are lubricated and 
cooled by the pumped liquid.

The pump bearings are also lubricated by the 
pumped liquid. 

Motor bearings

The motor ball bearings are grease packed and 
sealed for life. No further lubrication is necessary. 
Pumps from 4 kW and up have angular contact 
bearings.

pressure. 

Check that there are no leaks. 

Check that the motor is not overheating. 

Check the tripping of the motor-protective circuit 
breaker.
