CERAMPRO manufactures custom zirconia ceramic valve cores and sleeves for pharmaceutical metering pumps, dosing pumps, filling systems, and precision fluid control equipment. Made from high-performance zirconia ceramic (ZrO₂), these matched components help improve sealing stability, wear resistance, corrosion resistance, and dimensional accuracy while reducing contamination risk in pharmaceutical liquid handling and clean fluid control applications.
This product is mainly made from zirconia ceramic / ZrO₂. Zirconia ceramic is a high-performance technical ceramic material with high hardness, high strength, excellent wear resistance, and good surface polishing performance. It is suitable for pump and valve structures that require precise matching, repeated movement, and corrosion resistance.
For different pharmaceutical liquids, solvents, temperatures, and assembly conditions, CERAMPRO can help evaluate suitable ceramic materials, machining processes, and inspection solutions.
Zirconia ceramic valve cores and sleeves are mainly used in fluid control systems that require dosing accuracy, cleanliness, wear resistance, and corrosion resistance. They are suitable alternatives for some metal valve parts that may face wear, corrosion, or rust issues.
This product can also be used together with ceramic plungers, ceramic pistons, ceramic sleeves, ceramic seals, and other ceramic pump components for precision liquid dosing, transfer, and filling systems.
The main value of this product is not only the zirconia material itself, but also the matching accuracy between the valve core and sleeve. For metering pumps and filling systems, roundness, concentricity, surface roughness, and matching clearance can all affect dosing stability and sealing performance.
