DC76 Carbon Floating Ring Seal designed in accordance with API 692 as a replacement for labyrinth and gland packing ,the DC76 is an optimized design of the DC72,
rated for 0.8 MPa. The assembly includes a sleeve, segmented seal rings, seal ring holder ,auxiliary seals, seal gland, mounting plate, and drive mechanisms.
Technical Features:
1.Seal rings running contact-free.
2.High-strength, high-performance sealing materials for optimal performance.
3.Very small operation gap – low leakage.
4.Shaft sleeve with advanced wear and corrosion resistance treatment to prevent scoring.
5.Easy installation by split housing design.
6.Segmented seal rings for easy replacement.
7.Long-term operation time.
8.Cartridge design.
Solution Selection:
DC76-II: 2 seal rings for air transfer or non-critical leakage service
DC76-III: 3 seal rings for low-hazard process gases
DC76-IV: 4 seal rings for low-pressure, low-hazard process gases
DC76-V: 5 seal rings for low, medium-pressure steam and medium hazardous gas transfer
DC76-VI: 6 seal rings for medium-pressure steam,flammable, explosive hazardous gas service
DC76-VII: 7 seal rings for high-pressure steam and flammable,explosive hazardous gas transfer
Standard Support System:
With DERUI’s GCS74 nitrogen pressurization support system.
Custom configurations available per specific process requirements.
