API Plan 32 External Flush

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 is important to ensure the flush fluid is chemically compatible with the process fluid and that process fluid dilution is not a concern.

plan 32 

Benefits:

  • Provides clean flush fluid to the seal chamber when the process fluid is unsuitable to be used as the flush fluid
  • Increases the seal chamber pressure
  • Isolates the process fluid from the seal chamber when used with a close-clearance throat bushing

See page 23 of the Mechanical Seal Support Systems Applications Guide for additional details.
