Zirconia Ceramic Cermet Plunger is a high-performance engineering component made of zirconia ceramic and metal ceramic composite technology with excellent physical and chemical properties. The product exhibits extremely high wear and corrosion resistance, thanks to the inherent hardness of zirconia ceramic (up to 9 Mohs) and the enhanced toughness of metal ceramic, which enables it to operate stably in extreme temperatures (up to 1200°C) and high-pressure environments. Its low coefficient of friction (typically less than 0.1) ensures smooth reciprocating motion and effectively reduces energy loss and heat generation. The main functions include providing precise sealing and displacement control in hydraulic or pneumatic systems, preventing media leakage and improving the reliability and life of the overall equipment. This design is particularly suitable for scenarios that require long-term resistance to abrasive fluids or chemical corrosion, such as performing efficient power transmission in the core components of industrial pumps.
The plunger is widely used in multiple industrial fields, including the chemical, oil and gas, pharmaceutical and water treatment industries. In chemical pumps, it can handle strong acids, strong alkalis or abrasive slurries, significantly reducing maintenance frequency and extending equipment life; in oil drilling equipment, its high temperature resistance and impact resistance ensure continuous and reliable operation in deep well environments; and in pharmaceutical machinery, the product's high purity and biocompatibility avoid contamination risks and meet strict hygiene standards. In addition, its lightweight design and anti-fatigue properties also optimize energy efficiency, making it an ideal choice to replace traditional metal plungers, providing cost-effective solutions for a variety of harsh applications.
