Many types of fluid-filled equipment have a rotating shaft that penetrates a stationary housing. In this situation, some method is required to keep the process fluid within the equipment from leaking out. One technique is to compress packing material within a stuffing box against the shaft; another is to use a mechanical seal that consists of two flat faces that are perpendicular to the shaft.

Mechanics who work with mechanical seals need to know how they operate and how they are constructed. This course will cover the principles of operation behind different types of mechanical seals. It will cover common causes of seal failure and how to identify them. It will also demonstrate the removal and replacement of a mechanical seal in a centrifugal pump.

Learning Objectives

At the end of this course, you should be able to:

  • Identify the components of a typical mechanical seal
  • Describe how a typical mechanical seal operates
  • Identify commonly used types of mechanical seals
  • Describe some common causes of mechanical seal failure
  • Explain how to identify causes of seal failure by examining seal components
  • Have an understanding of the steps required to replace a mechanical seal

Most industrial facilities rely on fluid systems made up of piping, valves, pumps, and other components that contain and control fluids. Within these systems are numerous joints and connections which have the potential to leak fluid. Such leaks can be prevented or minimized through the use of compressible materials such as gaskets and packing. This course describes different types of gaskets and packing as well as methods of installation.

Learning Objectives

At the end of this course, you will be able to:

  • List factors that affect gasket operation
  • List some common gasket materials
  • Explain the purpose of packing
  • List the parts of a packing gland
  • List important points to observe when installing a new gasket
  • Describe how to adjust packing gland pressure
