Detailed introduction

Key selling points: Double-end face balanced structure + Adaptability to hazardous media + Multi-spring stable sealing + Customized materials
The Model 206 mechanical seal is specially designed for harsh operating conditions! Featuring a double-end-face balanced design, it is ideal for reactor applications involving flammable, explosive, toxic, and highly corrosive media. It is widely used in high-demand industries such as chemical processing, pharmaceuticals, and petroleum.
✅ Core Structure and Advantages
▶ Dual-end face balancing design: The atmospheric end is balanced, while the process medium end is unbalanced. Sealing is achieved by leveraging the pressure difference between the sealing fluid and the process medium. An additional circulation system is required. The sealing fluid pressure must be 0.05 to 0.2 MPa higher than the pressure inside the vessel, thereby forming a stable liquid film.
▶ Multi-spring + transmission sleeve: Provides uniform sealing force, ensures the seal rotates synchronously with the shaft, and maintains stable operation under complex working conditions.
▶ Customized materials: Friction pair and auxiliary sealing materials can be tailored to suit the characteristics of the medium, ensuring more reliable sealing.
▶ Industry applications: Fields with extremely high sealing requirements, such as chemical industry, pharmaceuticals, and petroleum.
🔥 Best choice for demanding operating conditions
Custom-designed for sealing hazardous media, with a stable structure and reliable sealing performance—this is the perfect choice for high-demand reactor equipment!
