Plan 32 is the most commonly used external flush seal support system in the API 682 standard.

Its core function is to inject clean, cool, and higher-pressure flush fluid from an external source into the seal chamber,

providing cooling, lubrication, cleaning, and isolation for the seal faces, making it suitable for severe operating conditions.
 
This system effectively lowers temperature, reduces wear, removes particles, and blocks harmful process media from entering the seal chamber.

It greatly improves seal reliability, extends service life, and reduces downtime for pumps, compressors, mixers, and other rotating equipment in harsh industrial environments.
