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
