Gaspac® D Double Cartridge Compressor SealGaspac® D Double Cartridge Compressor Seal

Brand Flowserve
Description Double cartridge compressor seal
  • Industries:
    Crude Handling and Treatment, Catalytic Cracking, Alkylation, Gas-to-Liquids, NGL, Delayed Coking, Hydrotreating, Hydrocraking, Gas Treatment, Products Pipeline, Distillation, LNG
  • Standards:
    APGS

Double cartridge compressor seal used on toxic and/or flammable gases, or when the process is contaminated with particles. The seal supply gas is maintained at a pressure higher than the pressure of the gas being sealed, which isolates the process gas from the atmosphere.

The Turbopac 2100 is a bi-directional balanced double mechanical seal. The constructional design on the gas side corresponds to a Turbopac 375, combined with a high-pressure seal on the atmospheric side. The special structural design of the seal faces allow higher pressures to be sealed at high circumferential speed. As a cartridge design, this seal provides unique benefits of a high pressure compressor mechanical seal.
