Non-contacting, Metal Bellows, Outward Pumping Dual Pressurized Gas Lubricated Seal is2874HTC

Reliably sealing high and low temperature process fluids up to 425°C (800°F), the is2874HTC incorporates unique HTC (high-temperature, corrosion-resistant) metal bellows technology with non-contacting gas lubricated technologies.

The is2874HTC is a cost-effective alternative to conventional wet contacting seals supported by various piping plans that provide liquid barriers or quenches to the primary seal interface. Instead of using a wet support system, the advantages of non-contacting gas lubricated technology can be used for reliable operation with either nitrogen, argon, or steam barrier significantly reducing your lifecycle costs.
