Core Advantages of Ceramic Piston Rod
Extreme Condition Performance
High pressure & impact resistance: Static pressure 150MPa, dynamic pulse (50Hz) >1,000,000 cycles without fatigue. Suitable for ultra-high pressure plunger pumps (RO systems, waterjet cutters).
Corrosion & wear resistance: Resists HF (<5%), high-temperature alkaline (50% NaOH @150°C), SiC slurry. Service life is 15× longer than stainless steel.
Precision Motion Control
Nano-precision surface: Cylindricity ≤0.003mm, Ra ≤0.05μm, friction coefficient <0.08 (water lubricated), supports high-speed reciprocation (>5m/s).
Zero-leak sealing: Works with ceramic/graphite seals, leakage rate <0.01mL/min, meets API 682 standard.
Lightweight & Energy Saving
Low inertia: Density 3.9g/cm³ (1/3 of steel), reduces driving energy consumption by up to 30%.
High temperature & creep resistance: Long-term heat resistance 600°C (Al₂O₃) / 400°C (ZrO₂), low thermal expansion, no deformation at high temperature.
