    • API Plan 53A

    Pressurized 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.

    If the seal support system pressure is maintained below designed pressure, In no case fluid will leak to atmosphere.

    It can be worked as a Plan 52 in case barrier fluid pressure is lost.

    Clean fluid film gives better seal life.
