MIDDIA High-Precision Zirconia Ceramic Plunger and Piston Shaft for Medical Filling Pumps

Engineered for high-precision pharmaceutical dosing, sterile liquid filling, cosmetics canning, and food-grade packaging machines, MIDDIA Zirconia Ceramic Plungers and Piston Shafts offer ultra-precise fluid volume control and unyielding durability. Manufactured from medical-grade, high-purity yttria-stabilized zirconia (Y-TZP), these intricate ceramic shafts feature precision-machined flow ports, keyways, and stepped geometry for dual metering and valve functions. Zirconia ceramic is 100% bio-compatible, chemically inert, non-porous, and non-metallic, ensuring absolute liquid purity without releasing trace metal ions or reacting with aggressive pharmaceutical agents, reagents, or acidic formulations. The contact surfaces are ground and precision-polished to micron-level tolerances, achieving a mirror finish that guarantees leak-tight sealing, eliminates dynamic seal wear, and resists crystallization sticking. Able to withstand CIP (Clean-in-Place) and SIP (Sterilization-in-Place) high-temperature steam protocols without thermal deformation, MIDDIA supports full OEM/ODM technical customization for dimensions, bore profiles, low MOQ orders, and rapid delivery for global medical equipment and filling machine manufacturers.
