Main Components of a Mechanical Seal

2026-07-08

A typical mechanical seal includes:

1. Seal Faces
The seal faces are the most important working parts. Common materials include carbon, silicon carbide, tungsten carbide, and ceramic. The selection depends on the operating conditions, such as pressure, temperature, speed, and the type of medium.

2. Secondary Seals
O-rings, elastomers, or bellows are used to prevent leakage between the seal components and the equipment shaft.

3. Spring System
The spring provides the necessary closing force to maintain contact between the seal faces during operation.

4. Metal Parts
Metal components provide mechanical support and protection. Materials such as stainless steel, alloy steel, and special alloys are commonly used for corrosion resistance.
