Mechanical Seals – Precision Sealing for Rotating Equipment

Mechanical Seals

A mechanical seal is a critical component used to prevent fluid leakage in rotating equipment such as pumps, compressors, and mixers. It consists of two precisely lapped sealing faces: one stationary and one that rotates with the shaft. These faces form a tight seal that keeps fluids contained—even under pressure and high speeds.

A mechanical seal typically includes four main components:

  • Primary sealing faces – flat surfaces that form the actual seal
  • Secondary sealing elements – O-rings, gaskets, or bellows to ensure tightness
  • Actuation mechanism – springs or bellows to maintain face contact
  • Drive mechanism – ensures the rotating part moves with the shaft

Mechanical seals are designed to provide long-lasting, low-maintenance sealing performance and are widely used in both industrial and marine environments.

Cross-Compatible Seals for Leading Brands
