API Plan 53 is a pressurized seal support system designed specifically for dual pressurized seals. By using barrier fluid with higher pressure than the sealed process fluid, this system can guarantee zero process leakage.
Features
1.The barrier fluid is pressurized directly by an inert gas.
2.If the barrier fluid pressure is lost, the system will operate as a Plan 52 system.
3.It prevents process fluid from leaking into the atmosphere.
4.Cool, clean barrier fluid forms a fluid film between the inboard counter-rotational seal faces, which extends the service life of the seal.
Benefits
The API Plan 53 system optimizes the fluid film condition between the counter-rotational seal faces, thereby extending the service life of both the mechanical seal and rotating equipment.
