Shaft packing

SHAFT PACKINGĀ S046

 

Refering to the soft rings of packing supplied by pump manufacturers. You need at least five rings to get a reasonable leak rate.

This drawing illustrates three rings of packing installed in the stuffing box; followed by a lantern ring or seal cage to provide lubrication to the packing, and two more rings of packing held in place and tightened by a packing gland.

Mechanical seals are replacing most of these leaking packings.
