Stuffing Box

Stuffing Box
Stuffing Box
Stuffing Box

The stuffing box (also known as a packing box or shaft seal chamber) is a traditional and classic shaft sealing structure and medium isolation component for industrial pumps. By loading flexible packing (such as compression packing) into the cavity and applying an axial tightening force with a gland follower, the packing expands radially against the pump shaft, thereby preventing fluid leakage and facilitating lubrication and cooling.
