A05 A07 A49 Slurry Pump Impeller High Chrome For G/GH Gravel Pumps

High Chrome Cast Wear-Resistant Long Life Work Life Mining Slurry Pump Impeller

Description

An impeller is a rotating component of a centrifugal pump which transfers energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid outwards from the center of rotation.The velocity achieved by the impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing. Impellers are usually short cylinders with an open inlet (called an eye) to accept incoming fluid, vanes to push the fluid radially, and a splined, keyed, or threaded bore to accept a drive-shaft.
The impeller made out of cast material in many cases may be called rotor, also. It is cheaper to cast the radial impeller right in the support it is fitted on, which is put in motion by the gearbox from an electric motor, combustion engine or by steam driven turbine. The rotor usually names both the spindle and the impeller when they are mounted by bolts.

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.
