Steam Turbine Seal

Floating Brush Seal

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.


Steam Turbine High Temperature

Permanently protect against contamination ingress and lubrication loss in process steam turbines in high-temperature environments (above 200°C [400°F]).

The High-Temperature Steam Turbine Bearing Isolator utilizes multiple features to ensure effective and permanent bearing protection. The stainless steel Flinger deflects steam away from the bearing housing while the unique stator/rotor design of the XX Interface blocks steam and other contaminants from entering the bearing housing. The D Groove protects against oil loss by capturing oil on the shaft and returning it to the bearing housing. Carbon Packing is used in high-temperature environments to drive the rotor.

The High-Temperature Steam Turbine Bearing Isolator can be custom engineered to meet the requirements of your application and operating environment.


Steam Turbine Low Temperature

Permanently protect against contamination ingress and lubrication loss in process steam turbines in low-temperature environments (below 200°C [400°F]).

The Low-Temperature Steam Turbine Bearing Isolator utilizes multiple features to ensure effective and permanent bearing protection. The unique stator/rotor design of the XX Interface blocks steam and other contaminants from entering the bearing housing. The D Groove protects against oil loss by capturing oil on the shaft and returning it to the bearing housing.
