The Zirconia Ceramic Equipment Piston is the premium solution for high-precision machinery operating in demanding environments. Unlike standard ceramics, Zirconia offers high fracture toughness, making it highly resistant to the mechanical shocks and pulsating loads found in industrial pumps and filling machines. Its thermal expansion coefficient is remarkably close to steel, allowing for tight-tolerance fitments without the risk of seizing during temperature fluctuations. With a mirror-polished surface that significantly reduces friction, our Zirconia pistons provide a long-life, contamination-free, and maintenance-saving performance for medical, chemical, and battery industries.
