What is the function of the sealing ring in a rotating mechanical seal?

The sealing ring in a rotating mechanical seal primarily functions to prevent fluid leakage between the rotating shaft and the stationary part of the seal. It creates a barrier that stops the pressurized fluid from escaping, thereby maintaining the integrity of the system and ensuring that the operating environment remains secure. This function is critical in various applications, such as pumps and compressors, where maintaining pressure and preventing fluid loss is essential for efficiency and safety.

The design of the sealing ring allows it to adapt to the movement of the shaft while still providing a tight seal. A properly functioning sealing ring minimizes wear and prolongs the life of both the seal and the connected machinery.
