2022-04-28 15:12:56

Now we offer various slurry pump materials
Metal: A05, A07, A33, A49, Cr30, 304 stainless steel, 316 stainless steel, duplex stainless steel
Rubber: R55, EPDM, Hypalon.
Resin: Polyurethane
Non-metal: ceramic
Slurry pump is a centrifugal pump for conveying slurry containing solid particles. Therefore, good wear resistance is generally required.
However, in many special conditions, we have to sacrifice wear resistance to get corrosion resistance.

Slurry pump for corrosion resistant media
In many cases, the slurry conveyed contains not only solid particles, but also corrosive characteristics.
When selecting materials for slurry pumps, it is important to determine the characteristics of the slurry.
In some cases, an expensive material may not be the best material.
For example, we go to stainless steel materials for conveying abrasive slurry, which are wasteful and ineffective.
It is also not recommended to use A05 slurry pumps to convey highly corrosive slurries.
For example, nitrate, sulfuric acid and strong alkali are very corrosive. So the corrosion resistance of the material is more important than the wear resistance.
How to choose slurry pump material
1. Light acid and alkali slurry with sharp-edged particles: A05, A07.
2. Acid and alkali slurry without sharp and large particles: R55 rubber material
3. Slurry with slightly stronger acid and alkali, with more particles: A49, Cr30, general power plant desulfurization industry.
4. strong acid and strong alkali but not high temperature with certain abrasive slurry: EPDM, Hypalon
5. strong acid and strong alkali strong abrasive high temperature high slurry: stainless steel.
6. super strong acid and alkali strong abrasive high temperature high slurry: ceramic
