Aramid Packing
Aramid packing is braided from premium aramid fibers impregnated with PTFE dispersion and high-performance lubricants. The material offers excellent chemical resistance, high elasticity, and minimal cold flow. Known as “synthetic metallic fiber,” aramid provides a tensile strength three times that of steel while weighing only one-fifth as much. This combination of strength and low weight allows aramid packing to withstand abrasive particles, high temperatures, and high shaft speeds.
It can be used independently or in combination with other packings and serves as a reliable asbestos-free sealing solution for pump systems.

Key Features
High Strength & Superior Wear Resistance
Aramid fibers deliver extremely high tensile strength and outstanding abrasion resistance, making them ideal for high-speed equipment and media containing solid particles.
Excellent Chemical Resistance
Resistant to acids, alkalis, and most chemical fluids, suitable for sealing a wide range of corrosive media.
Low Friction & Shaft-Friendly
PTFE or graphite lubrication ensures low friction, smoother operation, and minimized wear on shafts and sleeves.
Dense Structure & Reliable Sealing
Tightly braided construction with excellent compressibility and recovery provides dependable leakage control and long-term sealing stability.

Common Issues & Maintenance Tips
Aramid fiber has high strength and wear resistance, but excessive gland compression or insufficient lubrication may cause shaft or sleeve surface wear.
Maintenance Recommendations:
- Perform regular inspections during initial operation.
- Adjust gland pressure properly to avoid over-tightening or excessive looseness.
