Material Pump Adjustment
Operate the pump under normal conditions for a short run-in period. Examine the packing for
leakage. If leakage is excessive, tighten the locknuts evenly until there is only slight leakage
from the packing rings. This slight leakage is a necessary and normal condition for packing
and allows for expansion and proper seating.
REPLACING THE PACKING
1) Remove the locknuts, packing gland clips, spring clip, square head bolts, packing gland
and packing rings.
2) Clean the shaft and adjacent parts.
3) Examine the shaft and replace if excessively worn or scored.
4) Reassemble the components.
5) Draw up evenly on the packing gland to assure proper seating of the packing and then
loosen locknuts about 1/2 turn.
NOTE: Do not cock the packing gland. This may cause binding or excessive heating
of the shaft.
6) Run-in the pump as explained above.
NOTE: It is normal for the packing to leak.
