Ceramic plunger, mainly for zirconia ceramic plunger, alumina ceramic plunger, silicon nitride ceramic plugner and silicon carbide ceramic plunger, these plungers are widely used in chemical pump and injection pump, because of the high wearing resistance at high pressure and high temperature circumstance.
Zirconia ceramic plungers are widely used in high pressure chemical pump, like pneumatic pump, mtering pump and intensifier pump.
Advantage:
- High wear-resistanting,
- High resistance to elevated temperatures,
- High corrosion resistance
- High oxidation resistance
