Shaft seals

• Split housing design
• Segmented and self-adjusting seal rings
• Virtually maintenance- and wearfree
• Dry-running
• Suitable for horizontal and vertical use

• Split housing design
• Multi-part seal rings, radially cut
• Very small operation gap - low leakage
• Dry running
• Self-adjusting seal rings
• Seal rings bear radial shaft movements
• Compensates axial shaft movements
• 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

• Multi-part seal rings, radially cut
• Split housing design
• Short axial installation length (max. 36 mm)
• Very small operation gap
• Dry running
• Self-adjusting seal rings
• Seal rings bear radial shaft movements
• Compensates axial shaft movements
• Seals on both sides of the shaft
• Resistant to sea water
• 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

• Multi-part seal rings, radially cut on process side, overlapped mortised with gas tight joints on atmosphere side (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
