Slurry Pump Material

Slurry pump material

The slurry pump has a variety of wear-resistant and corrosion-resistant metal materials，ceramics and natural rubber accessories suitable for different conditions. Wear-resistant alloys mainly include A05, A07, A49, A33, and common materials such as GLH1-5, Cr30, SS304, 316, and 2205. The following is a detailed introduction.

High chromium wear-resistant cast iron A05 (KmTBCr27)

The material has high hardness, the hardness of heat treatment can reach HRC58~62, and it has good anti-abrasion performance. In terms of alkaline mixed liquid, it has good corrosion resistance and can be used in strong abrasive conditions. The casting process of high chromium cast iron is difficult and the processing is more difficult. However, its long life and moderate price make it the most widely used material for slurry pumps.

A07 (KmTBCr15Mo3)

A07 is a wear-resistant material developed on the basis of KmTBCr15Mo3. KmTBCr15Mo3 is currently recognized as an excellent anti-wear material in the world. It is generally used in the transportation of high-concentration, high-lift and strong-abrasive slurry. However, due to its high price, its application is limited. Heat treatment hardness: HRC58-70 Its high hardness, strong wear resistance, known as the wear-resistant king Brittle material for abrasive wear with moderate shock loads When the median particle size of the solid material is coarse, use Cr15Mo3, and when the median particle size is fine, use KmTBCr27.

A49 (duplex stainless white iron)

The material not only has the wear resistance of high chromium alloy, but also has good corrosion resistance and strong acid resistance. It is especially suitable for the pump used in the flue gas desulfurization system. It is a special metal material for the flue gas desulfurization pump. The use effect is very good ,long life. Heat treatment hardness: HRC44-50 Corrosion resistance: Austenite gives it corrosion resistance, it can resist the corrosion of sulfuric acid solution with pH 4, the corrosion resistance of sodium hydroxide solution with pH 13, and the corrosion resistance of CL- with a certain concentration. Wear resistance: Carbides impart wear resistance to the alloy, mainly against wear by gypsum solid particles.

A33 (duplex stainless white iron)

The material not only has the wear resistance of high chromium alloy, but also has good corrosion resistance and strong acid resistance. It is especially suitable for phosphoric acid and nitric acid pumps. It is a special metal material for phosphoric acid pumps. Heat treatment hardness: HRC35-50 l l Corrosion resistance: Austenite gives it corrosion resistance, and it can resist sulfuric acid solution with pH 1. Wear resistance: Carbide gives the alloy wear resistance, mainly resistant to phosphogypsum, nitric acid, sulfuric acid and other media.

Rubber lining

There are two categories of natural rubber and synthetic rubber, which are mainly suitable for fine particles without sharp edges and corners. Natural rubber has good elasticity, sealing performance and strong anti-abrasion performance. In the application of slurry pump materials, rubber has developed rapidly due to its excellent wear resistance, corrosion resistance and cavitation resistance, especially in power plant flue gas. Desulfurization conditions are particularly ideal, with a service life of up to five years.
