HM01B, Double Dry Gas Seals


Design Features:

  • Shrouded seat prevents secondary damage in the event of a seat fracture.
  • Seats are driven by pins, safer and more reliable.
  • Floating seats can improve adaptability.
  • Barrier gas should be set 0.2MPa above the process gas, little barrier gas leaks into the process side, so the process gas can be sealed completely.

Performance Capability:

  • Temperature:-60~200℃.
  • Pressure:≤2MPa.
  • Speed:≤180m/s.
  • Application:For use in the operating condition where the leakage of the process gas to the atmosphere can not be allowed, meanwhile, a little internal leakage of sealing gas is tolerated, e.g., wet gas compressors in refinery, low pressure chlorine compressors in chemical plant.
