Why Choose Us
Single Stationary Metal Bellow Mechanical Seals are engineered for reliability in demanding industrial environments where conventional seals fail. The O-Ring 85N model is specifically designed for applications requiring robust sealing performance, high-temperature resistance, and long service life. Unlike dynamic bellow seals, Single Stationary Metal Bellow Mechanical Seals feature a fixed bellow design, eliminating unnecessary movement and reducing wear.
✔ Zero-leakage performance – Welded metal bellows prevent fugitive emissions
✔ High-temperature resistance – Operates from -100°C to 400°C (-148°F to 752°F)
✔ Corrosion-resistant materials – Ideal for aggressive chemicals and acids
✔ Reduced maintenance – No elastomer degradation, longer lifespan
The O-Ring 85N Single Stationary Metal Bellow Mechanical Seals utilize:
Bellows Material: 316L stainless steel, Hastelloy C276, or Inconel 625
Seal Faces: Silicon carbide (SiC), tungsten carbide (WC), or diamond-coated
Secondary Seals: Fluoroelastomer (FKM) or PTFE for chemical resistance
✔ Laser welding ensures hermetic sealing
✔ Dynamic balancing for vibration-free operation
✔ Helium leak testing guarantees zero leakage
Acid & caustic pumps (sulfuric acid, hydrochloric acid)
Solvent transfer pumps
Crude oil transfer pumps
High-pressure hydrocarbon processing
Boiler feed pumps
Cooling water circulation systems
Sanitary-grade seals for hygienic applications
Pre-Installation Checks
Verify shaft runout (≤0.05mm)
Ensure seal chamber is clean and free of debris
Mounting the Seal
Carefully slide the Single Stationary Metal Bellow Mechanical Seal onto the shaft
Secure with manufacturer-recommended torque settings
Final Adjustments
Remove shipping clips (if applicable)
Perform a dry rotation test
Issue | Possible Cause | Solution |
---|---|---|
Excessive Leakage | Damaged bellows, misalignment | Replace seal, realign pump |
Overheating | Dry running, improper flush | Check lubrication, adjust flush rate |
Vibration & Noise | Cavitation, worn bearings | Inspect pump internals |
Maintenance Tips:
✔ Annual inspections for bellows integrity
✔ Vibration monitoring for early failure detection
✔ Flush system optimization for abrasive services
API 682 & ISO 21049 Compliance – Meets global industry standards
Customizable Designs – Multiple face materials and bellows configurations
Global Technical Support – Rapid response for troubleshooting
Final Recommendation:
For industries requiring high-performance, zero-leakage sealing, the O-Ring 85N Single Stationary Metal Bellow Mechanical Seals deliver unmatched reliability.
