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

An external fluid stream is brought to atmospheric side of the seal faces using quench and drain connections.
Leakage from seal faces is directed to a liquid collection system. A vessel with a high level alarm is provided for detection of excess leakage.
Leakage from seal faces is directed to a liquid collection system. A vessel with a high level alarm is provided for detection of cumulative leakage.
Throttle bushing in seal gland restricts seal leakage in event of seal failure. Pressure increase is detected by a pressure transmitter.
Orifice plugs in drain port restricts seal leakage in event of seal failure. Pressure increase detected by pressure transmitter.
Plugged connections for future provision to supply a buffer gas to a dual containment seal.
