INTRODUCTION:

The course commences with a solid review of the fundamentals, basic principles and looks at seal classification and design.

Through this course, you will understand the basic needs of mechanical seals, and by applying  what you learn, you will positively impact on the real costs of seal ownership to your company.

OBJECTIVES:

 

At the end of this workshop participants will be able to:

  • Demonstrate a sound understanding of the fundamentals of seal selection
  • Understand environmental considerations related to seals
  • See how the experts repair and rebuild seals for outstanding performance
  • Troubleshoot seals
  • Maximize mechanical seal life
  • Classify various seals, including special seal types
  • Explain considerations related to the materials used in seal construction
