PACKING
Operate the pump under normal conditions and, after a short run-in period, examine packing for
leakage. If leakage is excessive, stop the pump and follow the procedure described below.
A slight leakage is a necessary and normal condition for packing and allows for expansion and
proper seating.
To replace packing, remove the nuts, clips, packing gland and packing rings. (Packing hooks are
commercially available to assist in removing the packing rings.) Clean the shaft and adjacent
parts. Examine the shaft; if it is excessively worn or scored, replace the gear and shaft assembly.
