Steam Turbine Floating Brush Inpro Seal

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.
