Product Description
The Zirconia Ceramic Piston Sleeve for Metering Pumps is designed for precision pump assemblies where smooth piston movement, wear resistance, and stable fit are important. Made from high-purity zirconia ceramic (ZrO₂), this sleeve offers good resistance to wear, corrosion, and dimensional change during repeated pump operation.
In metering pumps, dosing systems, and filling equipment, the piston sleeve often works under repeated sliding or rotating movement. A stable bore, smooth surface, and accurate fit are important for reducing friction and supporting long-term operation. CERAMPRO can manufacture ceramic piston sleeves according to customer drawings, samples, or assembly requirements, including custom inner diameter, outer diameter, length, tolerance, and surface finish.
For projects that require alternative ceramic materials, alumina ceramic (Al₂O₃) can also be considered depending on the working conditions, cost requirements, and application environment..
Material System
Main Material: Zirconia Ceramic, ZrO₂
Optional Material: Alumina Ceramic, Al₂O₃, available upon request
Zirconia ceramic is often selected for precision pump sleeves and piston components because it offers a good balance of wear resistance, toughness, corrosion resistance, and dimensional stability.
For some applications, alumina ceramic can also be used when high hardness, electrical insulation, or cost control is required. The final material choice can be adjusted according to the fluid media, operating pressure, temperature, sealing requirements, and expected service life.
Application Scenarios
This zirconia ceramic piston sleeve is suitable for precision pump and fluid control applications where stable movement, wear resistance, and reduced metal contamination are important.
Dosing systems
Filling equipment
Chemical-resistant pump assemblies
Food and beverage filling equipment
Pharmaceutical dosing equipment
Cosmetic liquid filling systems
Typical media may include food liquids, beverage ingredients, pharmaceutical liquids, cosmetic liquids, cleaning fluids, chemical fluids, and other media where wear resistance, corrosion resistance, or lower contamination risk is required.
Core Advantages
Stable Fit for Pump Assemblies
For metering pump applications, the piston sleeve needs to work closely with the moving piston, shaft, or related pump component. CERAMPRO can control the inner bore, outer diameter, roundness, and surface finish according to customer drawings to support stable assembly and smooth movement.
Reduced Wear During Repeated Movement
Zirconia ceramic helps reduce wear in repeated sliding or rotating conditions. This makes it suitable for pump components that operate frequently under fluid contact or continuous movement.
Smooth Bore and Surface Finish
The inner bore and working surface can be processed through precision machining, grinding, and polishing to help reduce friction and support smoother piston movement.
Good Stability in Fluid Environments
Zirconia ceramic provides good stability in many clean, chemical, and mildly corrosive fluid environments. It can help reduce the risk of metal corrosion, wear particles, or surface contamination in sensitive pump applications.
Custom Manufacturing Support
CERAMPRO can manufacture ceramic piston sleeves based on drawings, samples, working conditions, and assembly requirements. Custom ID, OD, length, tolerance, surface finish, and material selection can be reviewed according to the actual project.
