Materials
High chrome alloy: A05, A07, A49, etc.
Natural rubber: R08, R26, R33, , etc.
Other material as per requests, like stainless steel, duplex stainless steel, Nickle alloy, Alloy 20, etc.

1. A05 is a wear resistant white iron that offers excellent performance under erosive conditions. The alloy can be effectively used in a wide range of slurry types. The high wear resistance of alloy BA05 is provided by the presence of hard carbides within its micro-structure. Alloy BA05 is particularly suited to applications where mild corrosion resistance, as well as erosion resistance is required.

2. A07 Marten-sic white iron with moderate erosion resistance.

3. A49 is suitable for low pH corrosion duties, where erosive wear is also a problem. The alloy is particularly suitable for Flue Gas Desulphu-rization(FGD) and other corrosive applications, where the pH is less than 4. The alloy can also be used in other mildly acidic environments.BA49 has an erosion resistance similar to that of Ni-Hard 1.

Production Process

- Aluminum Mold: Aluminum mold is able to ensure the accuracy in the cast process and make the blade curve infinitely close to the theoretical value. So that the efficiency of the pump can be improved.

- Heat treatment process: It can eliminate the stress, improve the hardness and prolong the work life.

- Boring and milling process: Professional boring and milling equipement to ensure accuracy.

- Product inspection: The products dimensions, hardness, compositon are strictly inspected by PV engineers.
