Pump Maintenance
6.1 Impeller Adjustment
As mentioned above, pump efficiency and component wear rate vary as a function of the GAP between the impeller and
the pump. Accordingly, the pump should have a GAP between 1 and 2 [mm] to achieve the best performance. For a
pump with centrifugal seal it is recommended to double this difference, so as not to increase the seal area pressure.
6.2 Bearing Lubrication
For reliable operation it is recommended to regularly inspect the bearing temperature and determine the frequency, the
amount of lubricant to be added and the date of the next inspection. These depend on the size of the bearing holder, the
operating speeds and mainly on the judgment of the field maintenance team according to the measured bearing
temperatures.
6.3 Grease Lubricants
Grease with the following technical specifications is recommended:
