Ceramic Slurry Pump Impellers

Jun 10, 2020

Ceramic Slurry Pump Impellers are made of Silicon nitride bonded silicon carbide material,It is mainly used for Wear and Erosion resistant working applications. Tobee® manufactures high quality slurry pump ceramic impellers and liners replacement parts for some all AH slurry pumps, which are 100% INTERCHANGEABLE.

Tobee® ceramic slurry pump impellers with silicon nitride bonded silicon carbide (Si3N4-SiC). There are many good characteristics of slurry pump ceramic impellers, 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 3.5 times as wearable as Cr15Mo3 (A07). However the weight of Si3N4-SiC material is only 1/3 of high chrome alloy slurry pump parts.

Tobee® ceramic slurry pump impellers show greater anti-abrasion performance than the other materials in impellers.

Contrast of Anti-Corrosive Performance


In regards of wear resistance, metals are only a compromise between conflicting requirements. Having only corrosion and no abrasion, it will be also possible to use Hastelloy. It’s the same with abrasion only. Abrasion in a neutral medium can be done by using Ni-hard or similar. Tobee‘s ceramic slurry pump impellers casting advanced ceramics covers both corrosion and abrasion perfectly. It could be a quite advantageous if there were solids in combination with non-neutral slurries, a leach or an acid (PH-value 0-12).
