Packing procedure
1.
Stuffing box and shaft sleeve must be clean and free of grit.
2.
Form packing over shaft or mandrel of same diameter. Carefully cut to packing length. Discard
rings cut too short.
3.
Pre-form each ring by coiling 1-½ turns.
4.
To install packing rings, do not pull straight. Expand the coil as a coil spring

5.
Expand first coil as shown and insert into stuffing box. Tamp packing to stuffing box shoulder
firmly with the gland. Note where the cut is positioned.
6.
Install second and third coils as required by assembly drawing, staggering the cut 90°F-120°F.
7.
Insert seal cage (lantern ring) into stuffing box, carefully noting its proper position on assembly
drawing. Failure to properly locate seal cage will result in insufficient packing lubrication. Packing
and shaft sleeve damage will occur.
8.
After packing and seal cage are properly installed, insert gland into stuffing box. Tighten gland
nuts finger-tight only. Shaft should turn freely.
9.
Follow pump start-up procedure. Turn on stuffing box lubricating liquid and start pump.
