Type 2800E
Non-contacting, Gas-lubricated Seals for Small-bore Rotating Equipment Type 2800E
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.
Product Description Type 2800E
Type 2800E is a state-of-the-art gas lubricated, non-contacting double seal cartridge for use in ANSI or DIN standard bore pumps or limited space applications. The 2800E provides zero emissions operation, extended seal life, reduced power consumption, and elimination of wet seal lubrication system. It uses an available pressurized inert gas source for positively sealing hazardous process fluids with zero emissions to atmosphere. Noncontacting, dry-running technology provides high performance sealing of heat sensitive or high purity fluids.
- For maximum achievable control technology (MACT) compliance in new or existing standard bore pumps
- For high reliability sealing of volatile fluids in chemical and petrochemical processes
- Double seal alternative for positive sealing of high purity fluids without the potential for product contamination
