Qualiseal Segmented Seals
In certain extreme applications, a part made of individual segments may meet your critical performance requirements better than a single-piece unit.
Segmented seals ride directly along the shaft and are primarily used in low-pressure applications.
These seals contain a series of segmented carbon rings which contact the shaft or rotor. Segments inside the seal housing are kept in the proper location by anti-rotation keys or pins. A secondary seal is formed by the axial spring loading of the seal rings against the internal surface of the housing face. During movement, a continuous seal is always in contact with either the primary or secondary sealing surfaces.
Features & Benefits
Benefits:
- Tolerance to unlimited shaft axial movement
- Prevents oil and contaminant migration into the process gas side
- Leakage rates remain constant over the life of the seal
Features:
- Rides directly along the shaft
- Special gap segments permit the seal to adjust dimensionally for minimal leakage
- Compression and garter springs ensure that segments remain in contact with mating surfaces during low delta pressure and shutdown conditions
Design Configurations:
- Various seal ring segment configurations
- Pressure-balanced segments
- Fractured rings
- Multiple seal labyrinth
- Internally pressurized seal
- Internally vented seal
Product Applications
- Aerospace Industry
- Industrial Industry
Ideal For:
- Gas seals and for sealing low-pressure liquids
