Properties of Silicon Nitride Ceramic Plunger


  • Corrosion Resistance: Made from high-quality silicon nitride material, our plunger sleeve exhibits excellent corrosion resistance. It can safely come into contact with a wide range of chemicals, including acids, alkalis, and saltwater, without any risk of failure due to corrosion. This ensures that the contacted liquid remains uncontaminated.
  • High Temperature Resistance: The silicon nitride plunger sleeve is designed to withstand extreme temperatures, with a normal use temperature exceeding 1300℃. This makes it ideal for applications in high-temperature environments.
  • Wear Resistance: With its high hardness and superior wear resistance, the silicon nitride plunger sleeve ensures stable and long-lasting performance. It boasts an impressive lifespan, making it a cost-effective solution for your machinery needs.
  • Lubrication-Free Operation: After polishing, the silicon nitride plunger sleeve exhibits a high surface finish and excellent self-lubrication properties. This means that it requires no lubrication oil, even in vacuum conditions, ensuring smooth and efficient operation.



Applications of Silicon Nitride Ceramic Plunger


  • Core Component of Plunger Pumps: Our silicon nitride plunger sleeve serves as the vital component of silicon nitride ceramic plunger pumps. With its exceptional corrosion resistance, wear resistance, and low friction properties, it ensures a long service life for the pump. This makes it ideal for a wide range of industries, including metallurgy, mining, chemicals, food production, and pharmaceuticals.
  • High-Performance Mechanical Parts: Silicon nitride plunger sleeves exhibit high mechanical strength, wear resistance, and durability. They can be manufactured into various mechanical parts for use in lubricating oil systems, hydraulic systems, and other applications where precise liquid flow control is required. The high strength and wear resistance of silicon nitride ensure reliable performance in demanding environments.
