API Piping Plans

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
