Advanced Mechanical Seals 

Mechanical, Fluid Control

Course Number: AMS-402

GPS-302-01O-Ring-Placement-for-Seal.jpg

Course Description:

Everything included in IMS-301 – Introduction to Mechanical Seals, but adds application considerations and theory appropriate for engineers and technical personnel working with any mechanical seals on rotating equipment.   How they work, the theory (and calculations) behind them, installation, and how to troubleshoot problems.  Selecting, specifying, and application considerations are a big part of this course.  Mechanical seals are expensive and improper handling or mistakes made during selection or installation can increase the maintenance budget dramatically.  Ability to troubleshoot seal failures and to make appropriate corrections will be a focus of this class.  Classroom exercises, assembly/disassembly of various seals, and other hands-on activities will be used to reinforce the concepts.  Students are encouraged to bring in their worst seal problems from their site.

​

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. Call, email or check the website for the next time this course is scheduled at the MTI training center session.
