Mechanical Seals

This comprehensive Activ® interactive multimedia training program consists of one lesson that trains participants to work effectively with mechanical seals. The functions, operation, and repair of common mechanical seals are demonstrated.

Audience: This program is excellent for all levels of maintenance personnel as well as for the multi-craft training needs of process and manufacturing facilities.

Mechanical Seals


Prerequisites: This lesson is designed for participants familiar with the basic operation and maintenance of pumps and other rotating equipment.

Description: This lesson covers the features, operation, and applications associated with three common types of mechanical seals: single, double, and cartridge. The lesson presents specific procedures for failure analysis and identification, seal removal, disassembly, reassembly, and installation.

Objectives:

  • Identify the basic components of a mechanical seal
  • Identify sealing points and applications in which packing is installed to control process leakage as well as the types of materials commonly used to make seal faces and elastomers
  • Select the appropriate seal design for a specific type of application
  • Verify the compatibility of seal materials with the process fluids for a particular application
  • Perform a failure analysis to determine the cause of seal failure and to identify the means to correct the problem
  • Remove and disassemble a failed mechanical seal
  • Remove and replace the o-rings on a mechanical seal
  • Perform the preliminary checks prior to seal installation
  • Reassemble and install a new or repaired mechanical seal
