10/8D Slurry Pump Closed Impeller Single Stage Dredge Pump Impeller

10/8D High Chrome Iron Cast Anti-Abrasive Hard Metal Mining Slurry Pump Impeller

Description

The impeller made of front cover plate, front liner plate and vanes, The vanes are distorted and have 3-6 blades. The vanes distribute blades back on the outer edge of the front cover plate and rear cover plate.

The impeller is made from wear-resistant high chromium alloy cast iron (hardness≥58HRC,impact toughness≥9J/cm2). The impeller is fixed on the pump shaft with double thread, and the thread tolerances are inspected according to the pitch diameter of thread. Disassembly rings are installed at the rear of the shaft sleeve to make maintenance easy.

Input dimension: 10"

Outlet dimension: 8"

Materials

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 A05 is provided by the presence of hard carbides within its micro-structure. Alloy A05 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.A49 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.
