What are the three sealing points of a mechanical seal?

The seal between the rotating ring and the stationary ring is achieved by an elastic element and the pressure of the sealing fluid, which generate an appropriate clamping force at the contact surface between the relatively moving rotating and stationary rings, causing their smooth, flat end faces to closely adhere to each other. A remarkably thin film of liquid is maintained between these end faces, thereby achieving the sealing effect.
The seal between the rotating ring and the stationary ring relies on an elastic element and the pressure of the sealing fluid to generate an appropriate clamping force at the contact surface between the relatively moving rotating and stationary rings, ensuring that their smooth, flat end faces are tightly coupled. A remarkably thin liquid film is maintained between these end faces, thereby achieving the sealing effect. This liquid film exhibits both dynamic and static pressures, playing a crucial role in balancing pressures and lubricating the end faces. The necessity for highly polished and perfectly flat end faces stems from the requirement to ensure perfect mating and uniform specific pressure—conditions essential for rotary seals.
