Question: What does a mechanical seal do?


A mechanical seal is a device used to seal the gap between two or more mechanical components, typically in rotating machinery such as pumps, compressors, and mixers. Its primary purpose is to prevent the escape of fluids, such as liquids or gases, from the system or the entry of contaminants into the system.

Mechanical seals typically consist of two main parts: a stationary component and a rotating component. The stationary component is usually mounted on the pump housing, while the rotating component is attached to the pump shaft. The two components are held together with spring pressure, creating a seal that prevents the fluid from escaping.

Mechanical seals have many advantages over other types of seals. They are more reliable, efficient, and require less maintenance than traditional packing seals. They are also capable of handling a wide range of temperatures and pressures, making them suitable for use in many different applications.
