GSS6000 <br/>Gas supply system

A Gas IN
C Drain

Gas supply system


  • Safe operation due to incorporated pressure regulator with upstream filter
  • System mounted on a plate
  • Easy wall or rack mounting


  • Coalescing filter with integrated sight-glass for monitoring liquid level to ensure safe operation even in case of poor gas quality.
  • Rigid base frame for easy rack mounting.
  • Wide range of flow monitoring to ensure utmost reliability of mechanical seals.

Standards and approvals

  • API 682 / ISO 21049
  • API 682 4th ed. Cat. 2/3 - 2CW-CS
  • API 682 4th ed. Cat. 2/3 - 2NC-CS
  • API 682 4th ed. Cat. 1 - 2NC-CS

Functional description

Buffered, gas-lubricated mechanical seals may only be used in conjunction with adequately pressurized gas (e. g. from a closed circular nitrogen pipeline provided by the operator). The minimum pressure overlay level (Δp) is specified for the individual seal types.

Main GSS functions:
- Filtering of the buffer and flushing gas
- Flow monitoring

Typical tasks for the GSS:
- Gas flushing for single seals
- Gas supply for tandem seals
