Motor and Pump Assembly
Disassembly Procedure
1. Remove casing cap screws, which hold adapter to casing.
2. Pry adapter from casing with pry bar or large screwdriver and remove adapter and
motor from casing.
3. Using a suitable holder to keep impeller from turning, remove impeller cap screw
washer and gaskets. Be careful not to damage precision surfaces of impeller.
4. Remove impeller and impeller key from shaft.
5. With impeller and key removed, the shaft sleeve and the mechanical seal assembly can
be removed as a unit. Sometimes, the sleeve is difficult to remove due to rust from
moisture accumulation. If this is the case, applying heat to the sleeve exterior with a
torch and/or a gear puller may help. The heat allows the sleeve to expand. However,
too much heat may allow the shaft to expand as well.
6. Remove adapter cap screws, which hold adapter to motor.
7. Remove adapter from motor by prying with pry bar or screwdriver.
8. With adapter removed, the seal and seat ring can be pushed out with the fingers.
