Carbon Floating Ring 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

• Multi-part seal rings, overlapped mortised with gas tight Joints (adjusting)
• Split housing design

• 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

• Torque transmission depending on application with set screw or as shrink fit
• Metallic coating (FMP 84) basically for applications without high oxidation
• Ceramic coating (EMP 98) basically for applications with high oxidation
• Design one- or two-piece

• Chamber seal (modular design - can be combined in any order), optional with housing and lid
• Very small operation gap - low leakage
• Dry running
• 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
• One-piece seal ring with titanium bandage
• Both side balanced seal ring inside chamber for short-term backpressure operation
• Seal ring axially spring-loaded – no swinging up at pressure-less machine operation
