Packing and Mechanical Seal Maintenance
7. Repack using the Hale packing kit recommended for your particular pump. For
most pumps, the packing is 7/16” (11 mm) square cut to the proper length.
8. Wrap one length of packing around the shaft to form a ring, and push the ring into
the packing housing. Install the second ring the same way, but stagger the joint
one-third of the way around from the first joint. (See 8.1 “Packing Seal Replace-
ment” on page 131.)
9. Insert foil separators between each packing ring. The foil separators must be cut
to fit the shaft.
10. Install the other rings, again staggering the joints.
11. Replace the gland and adjust accordingly. See Section 4: Preventive Mainte-
nance, heading “Packing Gland Adjustment” on page 77.
12. Operate the pump normally for about 15 minutes, and check the packing gland. If
necessary, re-adjust the packing nut accordingly.
8.2 MECHANICAL SEAL REPLACEMENT
Note: Before starting disassembly, use a center punch to match-mark the rear bearing
housing, mechanical seal housing, and pump body. This assists with proper alignment dur-
ing reassembly. If the mechanical seal requires replacement, order Hale Mechanical Seal
Replacement Parts Kit, p/n: 296-5210-50-0.
CAUTION!
MECHANICAL SEALS ARE PRECISION-ENGINEERED DEVICES. EXTREME CARE
MUST BE TAKEN TO ENSURE THAT NO DAMAGE OCCURS TO ALL MATING FACES.
ENSURE THAT THE FACES ARE ABSOLUTELY CLEAN THROUGHOUT THE ENTIRE
INSTALLATION. SOLID FACES MUST BE CLEANED WITH AN APPROPRIATE
DEGREASER AND A SOFT CLOTH.
