Newly packed pumps require initial packing adjustments to control leakage

Small initial adjustments are needed to prevent over-tightening of the packing gland

After initial startup, additional adjustments may be required

The packing should also be checked periodically and adjusted as needed

Slide the packing gland along the shaft out of the stuffing box
