PUMP PREPARATION
1. Turn off and isolate power supply.
2. Isolate and drain down pump of liquid.
3. To prepare the pump to accept the service kit parts, each pump part must be removed
noting its exact position and sequence.
Difficulties may be experienced in the removal of the impeller. To overcome this, 2
screwdrivers can be used to prize the impeller from the shaft as shown; ensuring equal
pressure is applied to each side of the impeller to avoid shaft bending.
4. Clean all the components not replaced by the service kit.
