Stuffing box vent

STUFFING BOX VENT S101

A vent hole can be drilled into the end of the stuffing box as shown in the drawing.

In vertical pump applications the stuffing box has to be vented to prevent the mechanical seal from running dry in trapped air.

With vertical pump applications this vent is better located in the seal gland rather than the pump stuffing box.
