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 Process Side Plans API Plan 11 recirculates flow from a high‐pressure section of the pump, typically the discharge piping, through a flow control orifice to the seal. Plan 11 is the default flush plan for most pumps. API Plan 11 Kit components shown solid and include some optional c...

API Plan 31 is used to remove solids from the flush stream by incorporating a cyclone separator into the flush tubing. Flow is routed from the discharge side of the pump through the cyclone separator. Clean flush fluid leaving the separator is routed to the seal chamber while fluid containing the so...

< Back to Process Side Plans API Plan 23 utilizes a circulation device, typically a pumping ring, to route the fluid from the seal chamber through a cooler before returning the cooled fluid to the seal chamber. A throat bushing isolates the cooled seal chamber flush fluid from the hotter pumped li...

API Plan 13 recirculates flow from the seal chamber to the suction side of the pump. This plan is common for vertical pumps. API Plan 13 Kit components shown solid and include some optional components. This plan: Removes heat and flushes particulate from the seal chamber Allows the...

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 14 combines Plan 11 and Plan 13. Flow is recirculated from the pump discharge into the seal chamber and from the seal chamber to the pump suction. Fluid flow is increased since the seal chamber is continuously vented, leading to higher cooling capacity. API Plan 14 Kit components show...

< 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 41 is a cooled version of Plan 31. Solids are removed from the flush fluid by incorporating a cyclone separator. Flow is routed from the discharge side of the pump through the cyclone separator. Clean flush fluid leaving the separator is routed through a cooler before being returned to the ...

< 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...
