What are the differences between mortar pumps and slurry pumps? What are the representative models between the two?

What exactly is the difference between a mortar pump and a slurry pump? Are they the same kind of pump? The answer is no.

Mortar pumps are a type of engineering plastic pump specifically designed for transporting corrosive slurry media, such as desulfurization circulating water, corrosive mineral slurry, and chemical materials containing particles, etc. The material of their flow-through components is ultra-high molecular weight polyethylene, and the shell material is usually cast iron or carbon steel. Simply put, it is a slurry pump used in the chemical industry.

The slurry pump is a pure metal pump. It is cast from high-chromium alloy or special alloy and has a semi-open impeller. It is suitable for conveying non-corrosive slurry containing a lot of impurities, such as slurry from mineral processing, sand and gravel mixed liquid, sludge, etc.

Which of the two is more wear-resistant?

The answer is that slurry pumps are more wear-resistant. Due to the characteristics of their materials, the wear resistance of plastic is inferior to that of alloy steel.

Between the two, which one is more corrosion-resistant?

When it comes to corrosion resistance, of course, mortar pumps are more resistant to acids and alkalis. Since engineering plastics are inherently acid-resistant, mortar pumps are definitely the best in terms of acid resistance.
