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.
Buffer gas is passed through the containment seal chamber to sweep inner seal leakage away from outer seal to a collection system and / or dilute the leakage.
