Mechanical seal failures are among the most frequent causes of pump downtime and process fluid releases. A clear understanding of how seals work, and why they fail, allows operators and technicians to protect seals during start-up and operation and to report problems before they escalate. This awareness course explains the principles of mechanical seal operation, the main seal designs and their variations, single, dual unpressurized, and dual pressurized arrangements, and the role of seal flush plans. Practical examples link seal behavior to everyday operating and maintenance decisions, such as correct venting and priming before start-up, avoidance of dry running, and monitoring of barrier and buffer fluid systems. The course provides a sound foundation for further training in seal installation and failure analysis.
Who Should Attend
- Process operators running sealed pumps and mixers
- Mechanical technicians new to seal handling
- Reliability and maintenance planners
- Storekeepers and procurement staff handling seal components
- HSE personnel concerned with fugitive emissions and process fluid releases
Learning Outcomes
