What Is a Mechanical Seal?

A mechanical seal is a device that helps prevent fluid leakage between a rotating shaft and a 

stationary housing in equipment such as pumps and compressors. It consists of two key components — a rotating face and a stationary face — that work together under spring tension to maintain a tight, leak-proof seal.

Mechanical seals are a more efficient, reliable, and maintenance-free solution compared to traditional packing or gland seals.
