Type 2800E
Non-contacting, Gas-lubricated Seals for Small-bore Rotating Equipment
The rotating mating ring features micromachined spiral grooves that compress an inert barrier gas and create a lifting force on the primary seal faces.
Gas-lubricated non-contacting seal faces operate without friction and without added heat.
No seal liquid is used, which preserves 100 percent product purity.
Pressurized dual cartridge design ensures zero-point-zero emissions, and reverse-balanced seal faces ensure 100 percent containment in the event of barrier gas pressure loss. No parasitic horsepower losses and extremely durable seal design provide very low cost of operation and ownership.
