Packing and Mechanical Seal Maintenance
Note: Removing the clearance ring renders it inoperative. It must be replaced. A usual good
practice, if one ring requires replacement, the other should be replaced as well. Also verify
the impeller clearance.
14. Inspect the rear clearance ring for wear and replace accordingly.
15. Removing the impeller may disturb the mechanical seal. A new seal must be
installed.
16. Inspect the oil seal in the rear bearing housing and replace if necessary.
Installing the Seal
1. See CAUTION! warning on page 133.
2. Clean the bore of the pump head using alcohol swabs. Solid running faces must
be cleaned with alcohol wipes, supplied with the Hale repair kit (p/n: 296-5210-
50-0).
3. Ensure that the pump body, mechanical seal housing, impeller bores and all mat-
ing surfaces of the mechanical seal assembly are absolutely clean throughout the
entire installation process.
4. Make sure the impeller shaft is smooth and free of burrs at the gear key slot and
bearing journals.
5. Clean the pump shaft with alcohol swabs.
6. Apply a generous coating of Pac-Ease Rubber Lubricant Emulsion (or equal) to
the mechanical seal bellows and the pump shaft and seal areas.
WARNING!
OIL AND GREASE WILL DAMAGE THE MECHANICAL SEAL FACE. DO NOT TOUCH
THE FACE OF THE MECHANICAL SEAL.
USE ONLY PAC-EASE RUBBER LUBRICANT EMULSION (OR EQUAL) ON THE RUBBER
MECHANICAL SEAL PARTS TO EASE INSTALLATION. USING AN OTHER LUBRICANT
CAN DAMAGE THE SEAL AND SEAT. MAKE SURE ALL SHAFT SURFACES AND THE
INSIDE OF THE SEALING BOOT ARE WELL LUBRICATED.
7. Lubricate the carbon seal, cup and seat assembly with Pac-Ease Rubber Lubricant
Emulsion. Without touching the carbon seal, slide the cup and seat assembly over
the impeller shaft. (See Figure 8-4: “Mechanical Seal Overview / Replacement”
on page 135.)
8. Using a soft pusher tube (2” / 51 mm PVC pipe) and keeping fingers away from
carbon seal ring, carefully push the cup and seat assembly in until they are
