![Steam Turbine Floating Brush Seals]( "Steam Turbine Floating Brush Seals")
Steam Turbine Floating Brush Seals. The Inpro/Seal Sentinel FBS extends maintenance intervals to 3-4 years over conventional carbon rings which normally last 6-12 months. Designed as a drop-in replacement for existing carbon rings, the Sentinel FBS eliminates costly casing modifications and rotor removal for seal installation. The Sentinel FBS is comprised of densely packed and flexible metallic bristles that bend with changing clearances between rotating and stationary surfaces. The brush serves as the primary shaft seal while a carbon element provides face sealing in the turbine’s casing. This unique technology provides an extra layer of protection that slows down the natural wear of downstream carbon rings – reducing maintenance, downtime and steam loss. Self-centering and lightweight, the Inpro/Seal Sentinel FBS's compliant brush allows "wear-in" for an optimum fit, providing predictable steam leakage over an extended operating life compared to carbon rings. This product is available for multiple manufacturers, including Elliott (YR turbines), Turbodyne, Terry, Coppus, Skinner, Worthington and Murray. Other designs are available upon request.
