The Ceramic slurry pump is so called the name all because of the main wetted parts of the slurry pump all made of ceramic Si3N4-SiC, such as ceramic slurry pump impeller, liner and volute.
Si3N4-SiC（silicon nitride bonded silicon carbide）is a kind of inorganic nonmetallic materials, We will call it ceramic hereafter.
Its wear resisting performance is 3.13times of Cr15Mo3 with Mohs hardness 8.9, only after Diamond and Cubic Boron Nitride. Compare with similar products, our ceramic density is about 5% higher than others, and double flexural strength higher at normal temperature.
Ceramic slurry pump are widely used in coal power generation, non-ferrous foundry, Mineral Processing, Coal Prep, Cyclone Feeds, Aggregate Processing, Fine Primary Mill Grinding, Chemical Slurry Service, Tailings, Secondary Grinding, Industrial Processing, Pulp and Paper, Food Processing, Cracking Operations, Ash Handling and other high corrosion and wear conditions.
