Features
Gas supply systems of the GSS range are specially designed for contact-free operated, gas-lubricated mechanical seals. The gas supplied from the supply network (e.g. air or nitrogen) is regulated/monitored by the GSS in accordance with the requirements of the seals being supplied. The GSS systems are equipped with alarm and/or switch-off points depending on specific safety requirements. Centralized monitoring of the measurement values is also possible on request.

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:
Typical tasks for the GSS:
Main GSS functions:
- Filtering of the buffer and flushing gas
- Pressure monitoring and regulation
- Flow monitoring
Typical tasks for the GSS:
- Buffer/barrier gas supply for double seals
- Gas flushing for single seals
- Gas supply for tandem seals
Notes
To assure a sufficient supply of the mechanical seal, pressure at entry of the supply system must be min. 2 bar (29 PSI) above max. barrier pressure always.
