Working Principle
The double-end face mechanical seal operates by forming a thin liquid film between two sealing faces. The inner seal contacts the pumped medium while the outer seal prevents leakage to the environment. Spring force maintains proper contact pressure, while the liquid film provides lubrication and sealing simultaneously.
Applications
- Petrochemical Industry: Pumps, reactors, compressors
- Pharmaceutical Industry: Reactors, centrifuges
- Food and Beverage Industry: Mixers, processing pumps
- Power Generation: Boiler feedwater and cooling water pumps
Maintenance Guidelines
Regular inspection of leakage conditions, proper lubrication and cooling, and timely replacement of worn components are essential for optimal performance and longevity.
