Combined Mechanical Seals and Dry Gas Seals Course
Introduction:
This five-day course offers an intensive and highly practical learning experience. Participants will acquire up-to-date information and gain a practical understanding of the fundamentals, applications, troubleshooting, failure diagnosis, installation, and maintenance of mechanical seals. The focus of the course will be on mechanical seals used in pump and compressor applications, and it will also cover recent designs such as dry mechanical seals.
Course Objectives:
At the end of this course, participants will:
- Have an understanding of the different types of seals
- Have learned about selection, operation and maintenance strategies
- Be able to troubleshoot seal problems
- Understand how seals are fitted
- Understand how seals are tested
- Have an understanding of API flush plans
Who Should Attend?
This course is directed towards:
- Supervisors
- Team Leaders in Maintenance, Engineering, and Production
