Ceramic Piston Rod

Our ceramic piston rod (plunger rod) is made of high-purity alumina (Al₂O₃ ≥99%) or Y-TZP zirconia ceramic. It features a mirror-smooth surface (Ra ≤0.05μm), pure white slender cylindrical body, and a dark high-strength metal connector (stainless steel/titanium alloy optional) at the bottom. The strong color contrast delivers a premium industrial precision look for black industrial equipment.

Core Design Highlights

One-piece molding

Seamless design, bending strength ≥400MPa, eliminates stress fracture risk of split plungers.

Composite bonding technology

Ceramic body and metal end joined by diffusion welding, tensile strength ≥250MPa, ideal for high-frequency reciprocating motion.

Основные преимущества

✅ 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 & износостойкость: 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 (>5РС).

Zero-leak sealing: Works with ceramic/graphite seals, leakage rate <0.01mL/min, meets API 682 стандартный.

✅ 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°С (ZrO₂), low thermal expansion, no deformation at high temperature.
