AESSEAL API plan 53A

Pressurised barrier fluid circulation in outboard seal of dual seal configuration through a seal support system. Circulation is maintained by using pumping ring in running condition and with thermosyphon effect in stand still condition

Description

Features

1. In no case will media leak to atmosphere (Provided the seal support system pressure is not lost).

2. Clean fluid film formation between the inboard seal faces gives better seal life.

3. Works as a Plan 52 arrangement if barrier fluid pressure is lost.

Use

1. Applications where no leakage to atmosphere can be tolerated e.g. hazardous, toxic, inflammable media.

2. For dirty, abrasive or polymerizing products where media is unsuitable as a lubricant for inboard seal faces.
