Wear Parts

Metal wear-resistant materials are widely used in over-flow parts, pipelines, elbows, etc. of slurry pumps. Commonly used wear-resistant materials are divided into:

1. Chromium-based wear-resistant cast iron: Cr20, Cr27; used for strong etched medium, mostly used for slurry pump flow parts, mud pump with elbows and short tubes, also suitable for alkaline medium with pH ≥5~12 .

2, molybdenum wear-resistant material: Cr15Mo3; used for heavy abrasive conditions, steel plant slag slag removal and high concentration of strong grinding media in mineral processing.

3, tungsten wear-resistant materials: W1, W2; for light abrasion conditions, mud, fine mortar, sludge and other light abrasive media.

4, nickel-based wear-resistant materials: hard Ni No. 1, hard Ni 2, etc.; mostly used for fine particles and light abrasive medium, have certain processing properties, can be drilled and tapped.

5, wear-resistant steel series: A1, A2, A3, A5; used to transport media containing coarse particles with impact, mostly used for dredging pump flow parts.

6, wear-resistant and corrosion-resistant series: A49, A33;

A49 is specially used for FGD desulfurization medium, medium with PH≥4 and chloride ion content less than 40,000ppm. A49 has excellent anti-scour performance, especially suitable for lime gypsum desulfurization environment.

A33 is specially designed for acid corrosive and abrasive media. It has excellent anti-scourability and corrosion resistance. It is often used to transport oxidizing slurry with pH ≥1, such as phosphogypsum in phosphate plant, nitric acid and sulfuric acid containing abrasive particles. , medium such as phosphoric acid.
