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 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...

< 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 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 65B monitors leakage in a single seal arrangement. Connected to the drain port on the gland, a reservoir is allowed to collect normal leakage. A level transmitter on the reservoir triggers an alarm in the event of excessive leakage. A valve on the outlet side of the reservoir is typically l...

API Plan 21 adds a cooler to Plan 11 for applications requiring better control of flush vapor margin. Flow is routed from the discharge side of the pump through an orifice and a cooler before being returned to the seal chamber. API Plan 21 Kit components shown solid and include some optional co...

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 22 adds a strainer to Plan 21. Flow is routed from the discharge side of the pump, through a strainer, an orifice, and a cooler before being returned to the seal chamber. The addition of pressure gauges on either side of the strainer allows the strainer to be monitored for servicing. In dry...

< 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 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...
