Mechanical Seal GT1911A

Double seals with gas flushing.




, ,


Latest generation gas lubricated double seal developed to safeguard the environment and eliminate process contamination.

The seal is designed with “Fluilift” non contacting face technology, and is pressurized with an inert gas that lubricates the faces and provides a gas barrier between process and atmosphere.

The seal incorporates laser etched grooves that maintain a controlled gap between the faces, even at low rotating speeds, eliminating friction, heat generation and process contamination.

Power consuption is also reduced. Designed using API 682 construction guidelines.
