Replacing the 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
the OASE specialist dealer or send the pump to OASE.
NOTE
The impeller unit contains strong magnets that attract magnetic particles (e.g. iron filings). Any
remaining particles can cause irreparable damage to the impeller unit and motor block.
Carefully remove any adhering particles from the impeller unit prior to installation.
• Dismantle the motor block as shown in the figure.
• Use a brush under clear water to clean the components.
• Check all components for damage. Replace damaged or worn components.
• Reassemble the motor block in reverse order.
When the impeller is pulled out, the bearing in the motor block may come loose. During re-
assembly, check that it is positioned correctly. If necessary, push the bearing into the mo-
tor block with the wide grooves first.
