AESSEAL API Plan 54

Pressurised external barrier fluid circulation from a central pressure source or by a stand alone pumping unit (e.g. AESSEAL® PUMPPAC™)

Description

1. Ensures higher flow rate, better heat dissipation and positive circulation of barrier fluid.

2. If maintained properly, is the most reliable pressurised plan for dual seals as compared to Plan 53 A/B/C.

3. Can also be given as a stand alone unit per pump.

4. Increases cooler efficiency due to higher flow rate the heat exchanger.

Uses:

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

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

3. For media with high pressure and / or high temperature and / or high heat generation between faces.

4. Wherever Plan 53 A/B/C circulation is insufficient to dissipate heat.
