API Plan 62 delivers an external quench fluid to the atmospheric side of the seal. A typical application in a refinery is the prevention of coking on seal faces in hot hydrocarbon service by employing a steam quench. Nitrogen or clean water may also be used to quench or cool and clean the atmospheri...

API Plan 51 is a quench system for use on the atmospheric side of a single seal. This system acts as a dead-ended reservoir for a fluid. API Plan 51 Kit contents shown solid and include some optional components. This plan: Prevents icing on the atmospheric side of the seal Is typic...

API Plan 76 collects leakage from the inboard seal in applications where normal process fluid leakage does not condense between the seals at ambient temperatures. In this piping plan, gaseous leakage from the inboard seal exits through the containment seal vent port in the gland. The orifice creates...

< Back to Between Seal Plans API Plan 75 collects leakage from the inboard seal in applications where normal process fluid leakage can condense between the seals at ambient temperatures. In this arrangement, a reservoir is connected to the containment seal drain port on the gland. Condensed leakag...

< Back to Process Side Plans API Plan 32 delivers a clean flush fluid into the seal chamber from an external source. Typically used with a close-clearance throat bushing, this arrangement can be used to ensure a higher pressure in the seal chamber. Flush fluid will migrate past the bushing, so it ...

< Back to Between Seal Plans API Seal Plan 52 utilizes a reservoir and circulates an unpressurized buffer fluid between the inboard and outboard seals. To provide positive circulation through the support system and into the seal, a pumping ring is employed. Frictional losses in the buffer fluid in...

API Plan 72 supplies a buffer gas from an external source between the inboard and outboard seals. For reliable operation, gas seals require a constant supply of clean, dry gas, typically nitrogen. The seal support panel contains a coalescing filter to remove any moisture and particulate present in t...

< Back to Between Seal Plans API Plan 74 supplies a pressurized barrier gas from an external source between the inboard and outboard seals. For reliable operation, dual pressurized gas seals require a constant supply of clean, dry gas, typically nitrogen. The seal support panel contains a coalesci...

API Plan 53A utilizes a reservoir and circulates a pressurized barrier fluid between the inboard and outboard seals. The typical source of pressurization is plant nitrogen. The reservoir should be set at least 20 psi (1.3 bar) above maximum seal chamber pressure. This is to ensure that leakage acros...
