GSS6001
Gas supply system

Features

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

Advantages

  • 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 - 3NC-FB
  • API 682 4th ed. Cat. 2/3 - 3NC-BB
  • API 682 4th ed. Cat. 2/3 - 3NC-FF
  • API 682 4th ed. Cat. 1 - 3NC-BB

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). For Plan 74 systems the barrier gas pressure level (p3) must always be higher than the pressure level (p1) of the sealed product, whatever the operational state of the machine. The minimum pressure overlay level (Δp) is specified for the individual seal types.

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

Typical tasks for the GSS:
- Barrier/buffer gas supply for dual seals
- Gas supply for tandem seals
