The purpose of vent lines in dual seals?
The purpose of vent lines in dual seals?
(OP)
Hello, I am not familiar with mechanical seals, so I apologize for my simple question.
What is the purpose of the vent lines in dual seals and gas seals? Must these seals vent continuously to flare? How much flow would be expected for a typical vent design?\
Thank you,





RE: The purpose of vent lines in dual seals?
Some plans such as plan 52 would be connected to a vapor recovery system and in that sense they would vent continuously. Most seal plans would only be vented prior to startup then the vents would be closed.
If you can be more specific about which seal plan you are thinking of using, it would help.
