Mechanical Seals - Mechanical Shaft Seals

What Are Mechanical Seals?

Mechanical seals are critical components for sealing the interface between rotating and stationary parts in various types of machinery, preventing fluid leaks and containing pressure.

These seals create a tight seal through two precisely machined faces — one rotating with the shaft and the other stationary pressed together with a spring mechanism. This arrangement ensures minimal leakage and maintains the integrity of the system or application.

Mechanical seals are widely used in pumps, compressors, and agitators. Their application helps enhance the efficiency, safety, and longevity of machinery.

Mechanical Seals Material

Mechanical seals are available in EPR, FKM, nitrile, and nitrile/EPR.
