GTS Seal for Steam Turbines
The most reliable steam seal inthe
industry, designed for real world applications.
Wavy Face technology gives a mechanical seal non-contactinglift off operation in real world applications yet can also sealliquids under upset conditions.• Able to recover from upset conditions because there are no
conventional face grooves to clog.• The Wavy Face design incorporates a positive sealing dam
and operates without face contact, hence, no wear.• Bi-directional operating capability improves interchangeability
and reduces installation and operation errors.

Conventional dry gas seals applied to steam turbine applications can fail prematurely due toclogging of grooved face patterns, sleeve distortions, and hang-up problems of dynamicsecondary sealing elements.

Flowserve expended considerable effort developing a mechanical seal that is especially designedfor steam turbine applications. The result is the GTS, providing the real benefits of a mechanicalseal in sealing steam turbines such as:
Tilt
WavinessAmplitude
Seal Dam
Bellows design helps eliminate secondary seal problems
GTS Inconel bellows along with lap joint, helps eliminate dynamicsecondary sealing element hang-up problems traditionallyexperienced in lightly loaded pusher seal designs.
Available as both integral and detachable designs
• Significant energy savings• Virtually no contamination of bearing oil resulting in enhanced MTBF
of the turbine• Elimination of hazardous “steam clouds” which improves plant safety
Distortion resistant sleeve design
Different temperatures across a sleeve causes different degrees of expansion creating facedistortion. The advanced design of theGTS sleeve greatly minimizes thisdistortion which helps to maintainseal face integrity, extending equipment MTBF.
