Non-Contact Dual Gas Seal FBG210
☑ Patented Inflectional Grooves
☑ Back-to-Back Arrangement
☑ API Plan 74 With GSP
Dry gas seals are used to prevent gas leaks in a variety of industrial applications, especially in high-speed and high-pressure centrifugal compressors, pumps and other rotating equipment. Unlike traditional liquid seals, dry gas seals operate without any liquid lubrication.
The FBG®210 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 back-to-back arrangement gas seal features a better stability and adjustability under high-temperature and high-pressure operations, providing a wider range of applications. 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.

- No contact of seal faces. In normal operation, seal faces separate and generate a sealing gap preventing friction and wear which prolong seal duration.
- Minimal power consumption. Diminished costs & energy requirements of accessories related with lubricating and cooling systems.
- Back to Back 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.
