Product Description

Product Description

(1)Features
• Multi-part seal rings, radially cut
• Split housing design
• Very small operation gap - low leakage
• Dry running
• Self-adjusting seal rings
• Compensation of radial and axial shaft deflections
• No sealing components mounted on the shaft and hence no additional shaft vibrations
• Seal rings running contact-free - sliding faces and machine consume no additional power

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