● Pressure: ≤2.5MPa

● Temperature: -120~400℃

● Shaft Diameter: 20~120mm

● Speed: ≤3600r/min

● Linear Velocity: ≤25m/s

● 2CW-CW dual seal of API682 arrangement 2 or 3CW-FB dual seal of API682

　arrangement 3.

● Secondary seal as the safety seal, the medium does not leak into the atmosphere.

● The rotating metal bellows prevent medium particles from depositing between the

　plates, achieving self-cleaning properties.

● This type of the seal is suitable for low temperature or high temperature working

　condition with higher safety requirements.

● Metal bellows rotary type

● Integral press-mounted non-compensating ring

● The auxiliary seal is flexible graphite
