Shaft Seal Replacement

The Shaft Seal consists primarily of two parts, a rotating member and a ceramic seal. The pump
requires little or no service other than reasonable care, however, a shaft seal may occasionally
become damaged and must be replaced. Note: The polished and lapped faces of the seal could
be damaged if not handled with care.
Pump Reassembly/Seal Replacement
1. When installing the replacement shaft seal, use silicone sealant on the metal portion before
pressing into the seal plate as shown. Note: Use extreme care when applying sealant.
Ensure that no sealant contacts the seal plate surface or the ceramic seal. Allow sealant
to cure overnight before reassembling.
2. Before installing the rotating portion of the seal into the impeller, be sure the impeller is
clean. Use a light density soap and water to lubricate the inside of the seal. Press the seal into
the impeller with your thumbs and wipe off the ceramic and carbon faces with a clean cloth.
3. Remount the seal plate to the motor.
4. Grease the motor shaft thread and screw impeller onto the motor shaft.
5. Screw in the impeller lock screw (counterclockwise to tighten).
6. Remount the diffuser onto the seal plate. Be sure the plastic pins and holding screw inserts are
aligned.
7. Grease the diffuser o-ring and seal plate gasket prior to reassembly.
8. Assemble the motor subassembly to the strainer pot-pump body.
9. Fill the pump with water.
10. Reinstall the pump lid and plastic clamp. See "Pump Strainer Basket Service" on page 29 for
details
11. Reconnect the RS-485 communication cable to the pump.
12. Prime the pump, see page 22 and 25.
