At Technetics Group, even though we established our manufacturing process over 25 years ago we are continuously looking for ways to improve our processes and ship quality parts to our customers with shorter lead-times. Our proprietary techniques allow us to manufacture a wide range of brush seal designs to meet your unique requirements.
Brush seals work by absorbing radial deflections from the rotor during transient operations. The seal then follows the rotor back to the steady state operating position to maintain minimum leakage. Each metal seal’s brush pack is composed of thousands of finely packed wire bristles. The bristle material, a cobalt/nickel alloy, is chosen to provide an optimal combination of wear properties and oxidation resistance. The back plates and side plates are typically fabricated from stainless steel or nickel alloys and are chosen based on the case material to account for thermal expansion.
Using a patented manufacturing and assembly process, we’ve developed an ideal rotating sealing solution for your most critical industrial applications. A circular seal that’s easy to install, our HELICOCARB®carbon brush seals use a network of soft, compressed carbon bristles inside the housing to deliver lower leak rates, lower friction, higher speeds and a longer product lifespan.
