slurry pumps volute liners Pump Parts Pump Spare Parts High wear resistance High corrosion resistance

The main accessory of the Slurry Pump is the overflow parts, and the sheath is one of the accessories.
The sheath is also known as the snail shell, because its shape is more like the shell of a snail. It is made of the same material as the Impeller, and there are many kinds of materials. We determine what material to use according to the characteristics of the conveyed slurry.

Cast iron: not wear-resistant, cheap.
High chromium alloy: wear-resistant, corrosion-resistant, more used in slurry pumps.
Natural rubber: wear-resistant, corrosion-resistant, generally more used for conveying slurry without sharp-edged particles, compared to high-chromium alloy will be a little more corrosion-resistant.
A49 material: this material is more expensive, 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, there are 316 stainless steel material, ceramic lining material. These few used less, generally for the special slurry will choose these two materials, and the price will be higher than other kinds of quite a few it.

slurry pump has a double pump shell structure, there is a single pump shell structure. The single pump shell structure is the sheath directly exposed outside. Common single pump shell structure of slurry pumps are Vertical Slurry Pump SP series, Gravel Pump G series, etc.. Double pump shell structure is in the sheath outside there is a layer, we call the pump body pump cover. Commonly, there are AH series slurry pump, ZJ series slurry pump, etc.
