White columnar zirconia ceramic plunger

User question: In high-pressure, high wear, or corrosive media environments, traditional metal plungers are prone to corrosion, wear, and have a short lifespan, which affects production efficiency and costs. How can we solve this problem?
Answer: The white columnar zirconia ceramic plunger, with its ultra-high hardness, corrosion resistance, and self-lubricating properties, can significantly extend its service life, reduce maintenance frequency, and improve equipment operation stability.
User question: In precision metering or high-pressure pumping scenarios, the dimensional accuracy and stability of the plunger are crucial. How can we ensure long-term precise operation?
Answer: The zirconia ceramic plunger adopts precision sintering and grinding processes, with dimensional tolerances controlled at the micrometer level, and almost no deformation at high temperatures, ensuring long-term stability and sealing performance.
User question: In the face of diverse industrial scenarios, can flexible customization services be provided to meet special needs?
Answer: We support full customization from material formula, size specifications to surface treatment, suitable for applications in multiple fields such as high-pressure pumps, medical equipment, chemical equipment, etc.

The white columnar zirconia ceramic plunger is made of high-purity zirconia (ZrO ₂) powder through isostatic pressing and high-temperature sintering, with a columnar structure design that combines high strength, wear resistance, corrosion resistance, and insulation properties. It is an ideal high-performance component to replace metal and plastic plungers.
Key features and advantages

1. Excellent wear and corrosion resistance
   -Vickers hardness ≥ 1200HV, wear resistance far exceeds stainless steel, suitable for media containing particulate matter.
   -Strong chemical inertness, resistant to acid, alkali, and organic solvent corrosion, extending the lifespan in chemical and electroplating environments.
2. High precision and stability
   -The dimensional accuracy can reach ± 0.002mm, and the surface roughness Ra is ≤ 0.2 μ m, ensuring sealing and smooth movement.
   -Low thermal expansion coefficient, no deformation under high temperature conditions, avoiding jamming problems.
3. Self lubrication and energy efficiency
   -The surface micro smooth structure reduces the friction coefficient, reduces lubrication dependence, and saves energy and consumption.

Application field
-High pressure pump equipment: chemical metering pump, cleaning machine plunger pump, petroleum injection pump.
-Medical devices: dental equipment, infusion pumps, precision transmission components for dialysis machines.
-Industrial automation: textile printing and dyeing, ceramic inkjet printers, 3C product testing equipment.

Customer Application Case (Anonymous)
-Case 1: A chemical enterprise replaced the original stainless steel plunger with a customized zirconia plunger (Φ 25 × 200mm) for use in strong acid medium pumps, increasing the service life from 3 months to over 2 years and reducing annual maintenance costs by 60%.
-Case 2: A medical device manufacturer used a miniature zirconia plunger (Φ 3 × 50mm) implanted into a high-precision infusion pump, reducing the product defect rate to 0.1%. The product passed FDA certification and was exported in bulk.
-Case 3: The manufacturer of environmentally friendly cleaning equipment purchased a surface polishing plunger group, which solved the problem of frequent leakage of high-pressure water guns and increased the continuous operation time of the equipment by 300%.
