MIDDIA High-Polished Zirconia Ceramic Plunger, Piston, and Shaft for Precision Pumps

Designed for high-pressure fluid metering, chemical dosing pumps, medical infusion systems, and precision mechanical drives, MIDDIA High-Polished Zirconia Ceramic Plungers and Shafts provide extraordinary dimensional accuracy and durability. Manufactured from premium-grade yttria-stabilized zirconia (Y-TZP), these precision cylindrical rods feature ultra-high flexural strength, superior fracture toughness, and extreme wear resistance. Each piece is precision ground and high-polished to achieve a mirror-like surface finish (Ra ≤ 0.05 µm), significantly reducing dynamic seal friction, minimizing wear on mating components, and extending overall pump service life. Being non-porous and chemically inert, high-purity zirconia ceramic offers exceptional resistance to strong acids, alkalis, and aggressive organic solvents—preventing corrosion and completely eliminating metal ion contamination in sensitive fluids. Capable of maintaining structural integrity under high temperatures and intense mechanical loads, MIDDIA provides fully customized outer diameters, lengths, grooves, and micro-tolerances with low MOQ wholesale options and fast delivery for global pump and equipment manufacturers.
