Dim. A: Distance between inner surface of the coupling hub and the
motor shaft end
Dim. B: Distance between inner surface of the coupling hub and
pump shaft end
+ = Inner surface of the coupling hub is higher as shaft end
- = Inner surface of the coupling hub is lower as shaft end
ATTENTION
High axial impact loads on both pump and motor shafts during the cou-
pling assembly process are to be avoided at all costs in order to prevent
any damage to the pump and motor bearings.
11.2 Repairs to the pump
In general, the pumps do not need servicing or maintenance and only need to
be sent to the manufacturer in order to be repaired. Upon request, the manu-
facturer provides training and information sheets on the subject of spindle sets.
12 Disposal
When disposing of the pump or the packaging materials the local and national
regulation for proper disposal must be complied with. Prior to its disposal, the
pump must be completely drained and decontaminated if necessary.
