Replacing impeller unit
Note!
The impeller unit is guided in the motor block by a bearing. This bearing is a wear part and should be
changed at the same time as the impeller unit.
• Changing the bearing requires specialist knowledge and tools. Have the bearing changed by your OASE
specialist dealer or send the pump to OASE.

The impeller unit contains strong magnets that attract magnetic particles (e.g. iron filings).
