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 Mechanical Seal Support Systems Seal Support System Atmospheric Side Plans Seal Plan Kits Swagelok-built atmospheric side plans for seal support are available as seal plan kits only. Each kitcontains everything needed for proper installation, including an engineered drawing, making it s...

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 typically used ...

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 65A monitors leakage in a single seal arrangement. Connected to the drain port on the gland, a reservoir collects normal leakage and is constantly open to drain. In the event of a seal failure, an orifice fitting on the outlet of the system allows a level transmitter to trigger an alarm due...

< 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 coalescin...

API Plan 12 recirculates flow from a high‐pressure section of the pump, typically the discharge piping, through a flow control orifice to the seal. In order to remove particulate in the flush stream and prevent clogging, flow passes through a strainer placed prior to the flow control orifice. The ad...

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 shown s...
