Steam Turbine Floating Brush Seals

SentinelFloating Brush Seal (FBS) 

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. 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.

Now available for multiple manufactureres, including Elliott (YR turbines), Turbodyne, Terry, Coppus, Skinner, Worthington and Murray. Other designs are available upon request. For more information, contact your local Inpro/Seal Representative here.

Decrease Periodic Maintenance. Decrease Steam Leakage. Easy Installation.

 

The Inpro/Seal Sentinel FBS:

  • protects downstream carbon rings from contamination and high pressure.
  • reduces maintenance, downtime and steam loss.
  • prevents secondary damage to bearings and leakage to atmosphere.
  • is a Plug-n-Play split design that provides a direct replacement of a carbon ring without necessitating rotor removal or costly casing modifications.
  • provides predictable leakage (low and stable) over an extended operating life compared to carbon rings.
  • is self-centering and lightweight.
  • utilizes a compliant brush seal that allows "wear-in" to optimize fit and eliminates incorrect bore sizing issues.
