Ceramic Pump and Valve Plunger

Case Background and Challenges

With the upgrading of industrial fluid control systems, pump and valve equipment are increasingly used in harsh working environments such as high pressure, strong corrosion, high temperature and high precision. Our customers cover global pump and valve manufacturers, chemical processing enterprises, semiconductor equipment suppliers and food medical production enterprises, and they face serious performance limitations when using traditional metal/plastic plungers in actual production.

As the core moving part of fluid control, the plunger directly determines the sealing performance, service life and operation stability of the whole pump and valve system. The defects of traditional plunger materials lead to frequent maintenance and replacement, which not only increases the production cost, but also causes production downtime and even fluid leakage and medium contamination, which brings great hidden dangers to the safe and efficient production of enterprises.

• Metal plungers are easy to wear and corrode in corrosive media, resulting in short service life (generally only 1-3 months)
• Plastic plungers have low mechanical strength and cannot adapt to high-pressure working conditions (≥10MPa)
• Poor surface precision of traditional plungers leads to serious sealing leakage and unstable pressure output
• Metal ion shedding of traditional plungers pollutes the transported medium, which cannot meet the high purity requirements of semiconductor/medical/food industries
• Frequent replacement of plungers leads to high maintenance costs and production downtime loss
