STS — Mechanical Seal for Steam Turbines

Reduce process steam loss, improve turbine efficiency

The STS mechanical seal has been developed in conjunction with a major oil refinery to replace existing carbon ring seals normally fitted to
steam turbines. Also STS adopts AESSEAL^® dry running gas compressor seal technology to provide a solution that significantly reduces the steam leakage typically associated with standard carbon ring seals.

Steam loss is a major problem in many industries as it incurs considerable cost, reduces efficiency, can be the cause of bearing failure and potentially represent a health and safety issue when it affects visibility around the turbine. The many variations of steam turbine can easily accommodate through AESSEAL’s modular approach to mechanical seal design.
Also This modular approach enables different flange designs, bolt patterns, etc.
to easily accommodate and more complex changes supported by our Engineering team and investment in modern manufacturing technologies. The seal is suitable for a range of major steam turbines that can find in a number of industries e.g. Oil and also Gas, Chemical, Pulp and Paper, etc.

Typical Benefits of Steam Turbine Mechanical Seal Technology

• Increased turbine reliability
• Reduced turbine maintenance costs
• Reduced bearing contamination
• Non-contacting technology extends life of seal
• Elimination of Shaft Wear – generated by the Carbon seal
• Greatly reduces steam loss and also increases efficiency
