The Zirconia Ceramic Precision Equipment Piston & Plunger Assembly is manufactured from high-toughness Y-TZP zirconia ceramic . It is used in metering, dosing, filling and high-pressure pump systems, helping reduce the wear, corrosion and fluid contamination associated with conventional metal components. It is suitable for precision fluid equipment requiring reliable delivery and stable operation.
The standard material is yttria-stabilized zirconia (Y-TZP). Mg-PSZ can also be evaluated for specific temperature, pressure or mechanical-load conditions. The final material grade is selected according to the working medium and operating environment.
Used in metering pumps, dosing pumps, filling equipment, battery electrolyte injection systems, high-pressure pumps and other precision fluid-handling equipment. View more ceramic pump components .
Available as individual pistons or plungers, matched ceramic sets, ceramic-to-metal components, or complete pump assemblies. Custom steps, holes, grooves, threads and sealing features can be manufactured from customer drawings, with precision grinding, polishing and dimensional inspection available.
