We have extensive experience in the retrofit of brush seals. We have installed brush seals in many turbines, primarily to improve or eliminate the use of carbon seals. Brush seals are used to increase efficiency in steam turbines by reducing seal clearance to near zero. Another advantage is that the brush seal eliminates the transfer of water into the bearing case, reducing the bearing case contamination.
In addition we have introduced brush seals to centrifugal compressors, blowers and cryogenic turbo expanders. Brush seals have been used successfully in the aerospace and aircraft industry for several years. As a result many thousands of hours of use have proven the reliability and efficiency of these seals.
