API Piping Plans

curve-down

The API Seal Plans elaborated in this section are as defined by API 682 4th edition / API 610 10th edition.

These are standardized flushing piping arrangements that are widely used in the industry. Customer specific variants of these plans are possible.

API Piping plans help to ensure good conditions for mechanical seal operation as well as improving safety and pump reliability.

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

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.

Plan 53B systems have been viewed as an engineering challenge around the world, often with long lead times. The innovative modular concept permits 12 modular options to be applied to create an API 53B System for any application.

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

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

Unpressurised external buffer fluid circulation from a central source.

Plugged connections for future use for Plan 62 or Plan 65.
