Disconnect pump from power source before servicing or handling pump Disassembly 1 With the pump located in a secure place remove the bolts fastening the seal housing to the volute The motor and impeller can now be removed as a unit 2 Lay the unit down on its side If the lower seal is to be removed it is recommended that the oil in the seal chamber be drained This can be done by removing the lower seal chamber plug and draining the oil into a holding container 3 To remove the impeller Using a proper wrench the impeller retaining bolt and washer must be removed This may require a piece of wood placed between the vanes to keep the impeller from rotating while removing the bolt Once the bolt has been removed tap lightly with a hammer around the outside diameter of the impeller to loosen from shaft and key After removing impeller the seal retainer needs to be removed to expose seal Caution The impeller is large and heavy and will need to be supported 4 If the lower seal needs removed first remove the compression spring that rides between the impeller and the seal assembly Next take a pair of screwdrivers and remove the compression ring that surrounds the rubber bellows on the rotating portion of the seal assembly Again using the screwdrivers pry the remaining portion of the rotating seal assembly off the shaft The ceramic stationary can be removed by placing a screwdriver between the rubber and the ceramic
