Steam Turbine Bearing Isolator
Permanently protect steam turbine bearings in both high and low temperature environments.
Inpro/Seal Steam Turbine Bearing Isolators utilize multiple features to ensure effective and permanent bearing protection against contamination ingress and lubrication loss on process steam turbines. They can be custom engineered to meet the requirements of your application and operating environment.
High Temperature – above 204°C (400°F)
A stainless steel flinger, driven by carbon packing, deflects steam away from the bearing housing while the unique XX Interface blocks steam and other contaminants from entering the bearing housing. The extended D Groove and a coalescing ring protect against lubrication loss by capturing oil on the shaft and returning it to the bearing housing.
Features and Benefits
- XX Interface – unique stator/rotor interface provides IP66 rated permanent protection against contamination ingress
- Stainless Steel Flinger – deflects steam away from the bearings
- Carbon Packing – drives the rotor in high-temperature environments
- Contamination Chamber – collects contaminants trying to enter the bearing housing and expels them through the expulsion port through centrifugal force and gravity
- D Groove – captures oil on the shaft and returns it to the bearing housing
