3×3 mm to 70×70 mm; special specifications or various non-standard products can be customized according to customer requirements.
Core Features
-
High-Tenacity Aramid Yarn: Braided from genuine aramid fibers, which possess a tensile strength stronger than steel, ensuring the packing does not tear or disintegrate under high-pressure mechanical stress.
-
PTFE & Lubricant Impregnation: Each strand is thoroughly impregnated with PTFE dispersion and high-temperature lubricants to reduce the naturally high friction of aramid fiber and protect the shaft.
-
Distinctive Yellow Appearance: The natural gold/yellow color of the aramid fiber provides a high-quality, professional look that is easily identifiable as a premium abrasion-resistant seal.
-
Square Braided Density: Precision-braided to a high density, preventing "leakage through the braid" and maintaining structural stability in high-velocity pumps.
Technical Advantages
-
Exceptional Abrasion Resistance: Specially designed for "dirty" media. It resists cutting and wear from sand, grit, slurry, and crystalline particles that would quickly destroy graphite or PTFE packings.
-
High Pressure & Velocity Limits: Capable of operating at peripheral speeds up to 20 m/s and pressures that would cause softer packings to extrude from the stuffing box.
-
Excellent Dimensional Stability: Exhibits minimal cold flow or creep, meaning once it is seated and adjusted, it requires far fewer follow-up tightenings.
-
Thermal Resilience: Maintains its mechanical properties in temperatures ranging from -100°C to +280°C, making it suitable for a wide range of industrial cooling and heating processes.
Common Applications
· Equipment Applications: Pumps, valves, rotating machinery.
· Applicable Media: Suitable for abrasive media containing solid particles; recommended for superheated steam, solvents, liquefied gas, syrup, and other abrasive fluids.
· Industry Applications: Chemical, petroleum, pharmaceutical, food and sugar, pulp and paper, and power industries.
