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.

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 impeller 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).

With many good characteristics of abrasion resistance, corrosion resistance etc. Now the slurry pump ceramic impellers 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 ceramic parts are 5 times as wearable as high chrome. However the weight of ceramic parts is only 1/3 of chrome parts.
