In industries such as chemical processing, metallurgy, and mining, delivery pumps are constantly exposed to challenging operating conditions. These include abrasive slurries containing solid particles, corrosive chemical environments, and the stress of high-temperature fluids. Such factors are highly destructive and can compromise pump performance, disrupt normal operations, and even contaminate the medium being transported.
Ceramic Plungers
To maintain stable performance under these extreme conditions, the choice of pump components — particularly plungers — becomes critical. Plungers operate with continuous reciprocating motion inside the cylinder, demanding exceptional properties such as high hardness, thermal stability, wear resistance, and resistance to acid and alkali corrosion. Without these characteristics, long-term reliability cannot be achieved.
Advanced technical ceramics provide an excellent solution. Ceramic plungers are manufactured from high-performance ceramic materials that offer superior hardness, outstanding wear resistance, excellent corrosion resistance, and the ability to withstand elevated temperatures. Their working surfaces are finished to a mirror-like smoothness, enhancing self-lubrication and reducing friction. Testing has shown that the wear resistance of ceramic plungers far exceeds that of traditional metal plungers, making them an ideal replacement that significantly extends the service life of pump components.
