MIDDIA Precision Customized Zirconia Ceramic Plunger and Pump Piston Rod (Item No. ZR08)

Engineered for high-precision metering pumps, pharmaceutical filling machinery, cosmetic dosing equipment, and high-pressure chemical dosing pumps, MIDDIA ZR08 Zirconia (ZrO2) Ceramic Plungers and Piston Rods deliver superior dosing accuracy and extended operational lifespans. Manufactured from Yttria-Stabilized Tetragonal Zirconia Polycrystals (Y-TZP), these ceramic plungers feature extraordinary fracture toughness, extreme flexural strength, and exceptional wear resistance under continuous reciprocating motion. Featuring a mirror-polished outer diameter (surface roughness Ra ≤ 0.05 μm) and tight geometric roundness tolerances, ZR08 ceramic plungers minimize seal friction, prevent fluid leakage, and eliminate micro-particulate shedding into sensitive process liquids. Chemically inert and non-reactive, zirconia ceramics resist corrosion from strong acids, alkalis, organic solvents, and corrosive chemical slurries without pitting or degradation. MIDDIA provides full OEM/ODM precision machining based on technical blueprints—including custom internal flow channels, side holes, stepped diameters, and mounting grooves—with low MOQ wholesale orders and rapid global factory delivery.
