What is the primary role of a mechanical seal?

The primary role of a mechanical seal is to prevent fluid leakage between stationary and rotating components. In many machines, such as pumps and compressors, there are parts that rotate and come into contact with fluids. The mechanical seal acts as a barrier, sealing the gap between the moving component (such as a shaft) and the stationary component (such as the housing) to prevent any leakage of the fluid being contained, which could lead to loss of efficiency, potential damage, or safety hazards.

This function is critical in maintaining the integrity of the system, ensuring that fluids remain where they are intended and do not escape into the environment or cause operational issues. By achieving a reliable seal, mechanical seals play a vital role in the overall reliability and performance of mechanical systems, particularly in industries where leakage can have significant consequences.
