Stuffing Box Cover and Seal Chamber Guide
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.
| Stuffing Box Cover/Seal Chamber | Application |

| Conventional Large Bore | Use for all mechanical seal applications where the seal environment requires use of CPI or API seal flush pans. Cannot be used with outside type mechanical seals. |
| Jacketed Large Bore | Same as Large Bore but also need to control temperature of liquid in seal area. |
