Ceramic slurry pump impellers
Ceramic slurry pump impellers are made of Silicon Nitride Bonded Silicon Carbide, aimed to Wear and Erosion resistant working application.
We proudly manufacture quality ceramic slurry pump liners and other replacement parts for some famous pump manufactures, which are 100% REVERSE INTERCHANGEABLE, no need to change your stock.

Slurry pump ceramic impellersWe are producing ceramic slurry pump impeller with silicon nitride bonded silicon carbide (Si3N4-SiC). There are many good characteristics of ceramic slurry pump impeller, such as abrasion resistance, corrosion resistance etc. Now the parts are continually provided for coal power generation, non-ferrous foundry, mining and others.
The corrosion and abrasion resistance of ceramic slurry pump parts are highly exceed ones made by high chrome alloy. The abrasion resistance of Si3N4-SiC material is 3.13 times as wearable as Cr15Mo3. However the weight of Si3N4-SiC material is only 1/3 of alloy parts.

Si3N4-SiC(silicon nitride bonded silicon carbide)is a kind of inorganic nonmetallic materials.
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.
