Features
- Multi-part seal rings, overlapped mortised with gas tight Joints (adjusting)
- Split housing design
- Lowest possible operation gap - lowest leakage
- Dry-running
- Self-adjusting seal rings
- Seal rings bear radial shaft movements
- Compensates axial shaft movements
- Short axial installation length
- No sealing components mounted on the shaft and hence no additional shaft vibrations
Advantages
- Easy installation by split housing design (shaft removal not required)
- Long-term operation time
- Maintainability
- Segmented seal rings for easy replacement
