SEALING

Our compressor seals are designed either to stop process gas from escaping, to stop contaminants from entering the process, or both.

We can offer gas-tight compressors when needed.

We can recommend a sealing arrangement according to your requirements.

Shaft Seals (Dynamic Seals)

Our compressors can be fitted with a combination of the following seals. Seals can generally be either single or dual.

  • Lip Seal

 

  • Labyrinth Seal

 

  • Carbon Ring Seal

 

  • Wet mechanical seal (water or oil lubricated)
    We can offer a high-pressure barrier system in accordance with API 682 seal plans 53B (self-circulating) and 54 (pumped).
  • Dry mechanical seal (gas lubricated)
    We can offer a high-pressure barrier system in accordance with API 682 seal plan 74
  • Magnetic Drive Coupling
    A hermetic seal is formed by the can (membrane) of the mag’ drive. The compressor is said to be ‘sealless’ at the drive shaft.
