Technical Data Sheet of Zirconia plunger piston
Zirconia plunger piston is one product of non-metallic inorganic materials. It is with obvious properties of Zirconia Ceramic are high hardness, high strength, high wear resistance, high corrosion resistance and high heat resistance. These advantages make Zirconia Ceramic an excellent material choice of plungers/pistons. Zirconia Ceramic Plungers/Pistons are for high pressure plunger pumps, automatic filling machines, medical controlled volume pumps, syringe pumps…
