Description
The CF-1410 Carbon Floating Ring Seal is a cartridge-construction shaft sealing assembly engineered for high-speed rotating equipment handling gases, vapours, fumes, exhaust streams, oil mist, water mist, and selected process media. Its floating carbon ring design operates with a controlled radial clearance, allowing the ring set to follow shaft movement while maintaining low leakage across the sealing chamber. Reference designs for this seal family use dry-running, self-adjusting carbon or PTFE compound rings, very small operating gaps, and segmented ring arrangements for maintainability.
For the target industry/application, the CF-1410 is best positioned for high-speed turbomachinery and process-gas sealing across chemical, petrochemical, oil & gas, refining, power generation, pulp & paper, food processing, metal production, mining, shipbuilding, and plant engineering. Gipfel’s product scope includes carbon floating seal rings in cartridge-type configurations, while reference carbon floating ring seal documentation identifies applications in compressors, steam turbines, fans/blowers, mixers, agitators, mills, dryers, bearing seals, and process-gas equipment.
Technical Key Features
- Floating carbon ring geometry accommodates radial shaft movement and thermal growth.
- Very small operating clearance for controlled leakage in gas, vapour, mist, and exhaust duties.
- Cartridge construction for controlled assembly, easier installation, and reduced site-fitment error.
- Dry-running, low-friction operation with no dynamic sealing element clamped directly to the shaft.
- Suitable for high sliding velocity applications where conventional contact seals or lip seals are unsuitable.
- Segmented or multi-part ring design enables replacement without full shaft redesign, depending on configuration.
- Optional buffer gas, suction, vent, or grease-barrier ports for demanding process-gas and contaminated services.
