AC6102 Rev 03 30
Check the shaft to ensure that it can be rotated after fitting
each packing ring.
Fit as many rings as possible into the stuffing box without
having any packing protruding, and without over-compressing
the packing
NOTE: The last ring in each box may not be required until
after the pump has operated for a period of time.
NOTE: When supplied, the seal cage will replace the third
packing ring from the bottom of the stuffing box. The seal
cage must be aligned with the seal water inlet when the
packing is compressed.
Bring the gland follower up squarely against the last packing
ring and tighten the nuts evenly to finger pressure.
9.4.5 Packing Adjustment
Install the proper flush set up.
Start the pump and allow the packing to leak freely at start-
up. During the break-in period, adjustments should be made
gradually (tightening the gland nuts one 1/4 revolution at a
time), allowing 5 to 10 minutes between adjustments.
After the break-in period, the leakage rate can be controlled
to 40 to 60 drops per minute.
