Wear resistant insulation zirconia industrial ceramic hollow plunger

Wear resistant and insulating zirconia industrial ceramic hollow plunger is an industrial precision component made of high-purity zirconia (ZrO ₂) material and manufactured through precision machining technology. Its unique material properties and exquisite craftsmanship design enable the plunger to demonstrate outstanding performance and broad application prospects in multiple industrial fields.

Product Features
Wear resistance: Zirconia ceramic plungers are known for their extremely high hardness (hardness values typically exceed HV1200, with some products using gradient sintering processes reaching HV1400) and excellent wear resistance. This characteristic enables it to maintain surface smoothness for a long time in high-pressure, high flow rate fluid transmission environments, reduce friction losses, and extend its service life.
Insulation: Zirconia ceramics are a high-quality insulation material with excellent electrical insulation properties. This makes hollow plungers perform well in applications that require electrical isolation or high voltage, such as connectors, switches, and other components in electronic devices.
Corrosion resistance: Zirconia ceramic plungers exhibit excellent corrosion resistance to various chemical media, including strong acids, strong bases, and organic solvents. This characteristic makes it highly valuable in corrosive environments such as the chemical industry, oil and gas extraction.
High temperature resistance: Zirconia ceramic plungers can maintain stable physical and chemical properties in high temperature environments, typically withstanding temperatures up to 1400 ℃ or higher. This makes it widely used in high-temperature components such as aerospace and automotive engines.
Self lubrication: The plunger working surface adopts a unique microporous structure design, which has self-lubricating effect, reduces the dependence on traditional plunger pump sliding friction and lubrication, and improves operating efficiency and reliability.
High precision: Through high-precision CNC machining and ultrasonic polishing technology, the surface roughness of the plunger can reach Ra ≤ 0.005 μ m and cylindricity ≤ 0.5 μ m, ensuring extremely high dimensional and shape accuracy.

Application area
Chemical industry: used in chemical reactors and pump valve systems to provide excellent anti-corrosion protection and extend equipment life.
Oil and gas industry: Excellent performance in high-pressure/high-temperature environments, suitable for equipment systems in oil drilling and natural gas extraction operations.
The automotive industry: Due to its excellent temperature resistance and wear resistance, it is widely used in automotive engines, which helps to improve engine efficiency and performance.
Medical industry: Due to its excellent biocompatibility and durability, it can be used for dental implants, orthopedic repair materials, and medical infusion pumps.
Electronics industry: used as precision mechanical components such as connectors and switches in high-performance electronic devices to maintain the stability of electronic components.
Aerospace industry: Its lightweight and sturdy performance makes it suitable for high-temperature components and propulsion systems inside aerospace vehicles.
