water jet Ceramic plunger (Silicon nitride, Si3N4

Wear resistant Anti-corrosion Resistant to high temperature Production range:15 60mm diameter and 100 350mm length Features: 1) Materials:Si3N4 2) Color:Black(gray) 3) Usage: industry or other field, high temperature, hardness,corrosionresistant 4) Application Pressure range: 10 400MPa(100 4000bar) 5) Surface roughness: 0.02 0.01Ra, No scratch 6) Advantage: Self-lubricate 7) Long life time: >2000hrs(400MPa water jet ceramic plunger) The ceramic plunger is wear resistant, anti-corrosion, resistant to high temperature, and can endure impact. The ceramic plunger has a service life about 7 10 times longer than metal plunger. As critical part in plunger pump, ceramic plunger is widely used in electrical industry, ceramic industry, oil industry, food industry, medical industry, chemical industry and especial for water jet cutting machineetc. to replace metal plunger. These ceramic plungers was produced by cold iso-static pressing.
