API Plan 23 Cooled Flush, Recirculated through Seal Chamber

API Plan 23 utilizes a circulation device, typically a pumping ring, to route the flush 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 liquid.

plan 23 

Benefits:

  • Provides an isolated cooled flush fluid in the seal chamber
  • Reduces cooler duty due to isolated flush fluid, extending the life of the close-clearance throat bushing

See page 19 of the Mechanical Seal Support Systems Applications Guide for additional details.
