Packing and Mechanical Seal Maintenance
8.1 PACKING SEAL REPLACEMENT
When the packing adjustment has reached its limit, a single ring of packing can be
added. However, it is usually more efficient to repack the pump. (See Figure 8-1:
“Pump Packing Seal Overview.”) Also see Figure 8-2: “Packing / Mechanical Seal
Assembly Overview” on page 132.

Review preceding sections “Before You Begin...,” on page 103 and “Cleaning and
Inspection Guidelines,” on page 106.
The three rings adjacent to the packing gland can be replaced without disassembling
the pump. The ring in front of the lantern does not need to be replaced. (See Figure 8-
1: “Pump Packing Seal Overview.”)
WARNING!
