Stuffing Box Cover and Seal Chamber Guide

The selection guide on this page and the Seal Chamber Guide are designed to assist selection of the proper seal housing for a pump application.

JACKETED STUFFING BOX COVER

Designed to maintain proper temperature control (heating or cooling) of seal environment. (Jacketed covers do not help lower seal face temperatures to any significant degree). Good for high temperature services that require use of a conventional double seal or single seal with a flush and API or CPI plan 21.

JACKETED LARGE BORE SEAL CHAMBER

Maintains proper temperature control (heating or cooling) of sea environment with improved lubrication of seal faces. Ideal for controlling temperature for services such as molten sulfur and polymerizing liquids. Excellent for high temperature services that require use of conventional or cartridge single mechanical seals with flush and throat bushing in bottom of seal chamber. Also, great for conventional or cartridge double or tandem seals.
