Non-Contact Dual Gas Seal FBG220
☑ Patented Inflectional Grooves
☑ Face-to-Face Arrangement
☑ API Plan 74 With GSP
Dry gas seals are used to prevent gas leaks in a variety of industrial applications, especially in centrifugal compressors, pumps and other rotating equipment. Unlike traditional liquid seals, dry gas seals operate without any liquid lubrication.
The FBG®220 utilizes patented inflective grooves technology, which generates hydrodynamic force during operation, causing the face to separate from the seat and creating a rigid gas film for effective sealing. Additionally, this technology significantly reduces friction and wear, thereby enhancing sealing efficiency and lifespan.
This face-to-face arrangement gas seal features a shared rotating ring, making it exceptionally lightweight. Its integral sealing ring resists deformation, providing superior precision and wear resistance. Utilizing Plan 74 with N2 or a gas support system eliminates the need for cooling water or other accessories, ensuring a clean working environment with zero VOC emissions. The cartridge-type design facilitates easy installation and reduces maintenance costs, while guaranteeing safety, reliability, and an eco-friendly sealing solution.

- Minimal power consumption. Diminished costs & energy requirements of accessories related with lubricating and cooling systems.
- Low power consumption due to non-contacting faces. Seal faces generate significantly less heat and torque, and will not affect turbine's stability.
- Face to face seal arrangement. Unwetted springs. Stress & corrosion free. Eliminated matters crystalizing effect and impurities clogging effect problems.
- Merely N2 as system source. Cooling system not required. Achieved clean operating condition and environment.
- Less power requirement. Power consumption of gas seal is just 5%~12% in comparison to traditional wet seal; conserves significant amount of wearable materials and support systems.
- Fitted with N2 control panel. Must maintain stable clean nitrogen. Attained VOC zero leakage.
- No discarded lubricating oil or cooling fluid. Reduced consumption of oil & water resources. Observed co-existence with the environment.
- Designed for various rotating equipment, such as pumps, steam turbines, mixers, agitators, blowers, windmills, etc.
