• Lowest possible operation gap - lowest leakage
• Overlapped mortised seal rings
• Dry-running
• Self-adjusting seal rings
• Compensation of radial and axial shaft deflections
• Short axial installation length
• No sealing components mounted on the shaft and hence no additional shaft vibrations

(2)Advantages
• Easy installation by split housing design (shaft removal not required)
• High reliability
• Maintainability
• Segmented seal rings for easy replacement
• Maintenance-free
