Slurry pump spare parts - Manufacture of volute

Jan 23,2024

The sheath is also called the volute, because its shape is more like the shell of a snail. It's made of the same material as the impeller and there are many different materials. We determine the material to use according to the characteristics of the slurry.

Cast iron material: not wear-resistant, cheap.
High chromium alloy: wear resistance, corrosion resistance, in the slurry pump used more.
Natural rubber: wear-resistant, corrosion-resistant, generally conveying non-angular particles of the slurry used more, compared with high chromium alloy will be a little corrosion resistance.
A49 material: This material price is relatively high, generally used to transport more corrosive slurry. In the desulfurization pump used more.
The above are several materials commonly used in slurry pumps. In addition, 316 stainless steel, lined with ceramic material. These several are used less, generally for special grout will choose these two materials, and the price will be much higher than the other several.
