Introduction to Mechanical Seals
Fluid Control, Mechanical
Course Number: IMS-301
Course Description:
A short and jam-packed one day course that introduces the trainee to shaft mechanical seals: how they work, then theory behind time, how to install them, and how to troubleshooting problems. Mechanical seals are expensive and improper handling or mistakes made during installation can add a lot of money to the maintenance budget. “Reading seal faces” to troubleshoot inherent problems and choosing the correct materials for stationary faces, rotating faces, and secondary static seals will be discussed. Single, double, tandem, component, and cartridge seals will be used in the class. Various seals are disassembled and reworked to return them to service.
​
Each student will receive class books, work activity sheets, self-test progress evaluations, as well as questions from the instructor to make sure they understand the material presented. It is expected that an attendee will leave the class with the basic knowledge of the subject and possess new found skills to better equip them when they return to their job. A certificate suitable for framing will be issued to each attendee who successfully completes the course.
