C. Mechanical Seals

Mechanical seals are precision-engineered seals used to prevent the leakage of fluids in high-pressure and high-temperature applications. Unlike O-rings and lip seals, mechanical seals require careful installation and maintenance due to their complex design. They are commonly used in industrial pumps, compressors, and mixers, where traditional seals may not provide sufficient sealing performance.

Applications of Mechanical Seals

  • Centrifugal pumps
  • Reactors and mixers
  • Steam turbines
  • Process compressors
  • Submersible pumps

Benefits and Limitations of Mechanical Seals

  • Superior sealing performance in demanding conditions
  • Suitable for high-pressure and high-temperature applications
  • Complex installation and maintenance
  • Higher initial cost

II. Applications of Industrial Seals

Industrial seals play a pivotal role in various industries, ensuring the efficient and safe operation of machinery and equipment. Let’s explore some of the key industries where industrial seals find extensive application.
