Next-Generation Packing Technology
Hongwo’s Oil-Immersed Aramid Packing redefines high-pressure sealing through its proprietary saturation process. By impregnating premium aramid fibers with high-temperature synthetic oils during manufacturing, we create packing that delivers continuous internal lubrication – eliminating the need for external grease injection while providing unmatched durability in extreme conditions.
Engineered for Critical Service Applications
◈ High-Pressure Hydraulic Systems – Maintains seal integrity beyond 250 bar
◈ Turbine Shaft Seals – Withstands 10,000+ RPM with zero lubricant depletion
◈ Offshore Drilling Equipment – Saltwater-resistant with 5X longer life than standard packing
◈ Steel Mill Rolling Mills – Survives scale particles and thermal cycling to 400°C
◈ Mining Slurry Pumps – Oil barrier prevents abrasive particle penetration
Performance Specifications
| Core Parameter | Technical Benchmark | Industry Advantage |
|---|---|---|
| Oil Retention Capacity | 18-22% by weight | Outlasts surface-lubricated packing 3:1 |
| Pressure-Velocity (PV) Limit | 750,000 psi·ft/min | 45% higher than dry aramid |
| Break-In Period | <8 hours operation | 70% shorter than conventional packing |
| Oil Activation Temperature | 65°C (149°F) | Optimal viscosity achieved at operating temp |
| Re-Lubrication Interval | Not required | Permanent oil reservoir in fiber matrix |
Exclusive Technical Features
✦ Depth-Impregnation Process – Oil penetrates fiber core rather than surface coating
✦ Thermal-Responsive Oil Release – Increased flow at higher temperatures
✦ Aramid-Oil Bonding Technology – Patented fiber treatment prevents oil separation
✦ Dual-Layer Construction – Outer dry-braided shell contains inner oil-saturated core
