Sand gravel suction flux parts replacement anti-abrasive hard metal high chrome cast Dredge pump impeller
high chrome cast iron slurry pump impeller
Description
Completely interchangeable with NH, L, M, HH, SP slurry pumps and G/GH gravel pumps For unlisted slurry pump parts, OEM service offered. Drawings needed
An impeller is a rotating component of a centrifugal pump which transfers power from the motor or engine that drives the pump to the medium being pumped by accelerating the medium 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.
Materials
High chrome alloy: A05, A07, A49, etc.
Natural rubber: R08, R26, R33, R55, 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 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
| Hard metal | A05 | High chrome white iron, Cr 25~30% | ≥56 | Impeller / Liner | Used for higher wear condition with PH between 6 to 12. Such as slurry pump, Dredging pump. Widely used in mine, coal, power plant, dredging, steel, building material. |
| A07 | High chrome white iron, Cr / Mo alloy. | ≥59 | Impeller / Liner | Used for higher wear condition with PH between 6 to 12. Such as slurry pump high abrasive. Widely used in mine, coal. | |
| A49 | High chrome, Anti-corrosive Cr/Mo/Ni alloy | ≥42 | Impeller / Liner | Used for FGD(Gypsum slurry circulating)and other corrosive application. | |
| A33 | High chrome, wear resistant Anti-corrosive Cr,/ Mo/ Ni alloy | ≥36 | Impeller / Liner | Used for Phosphorus chemical industry, Phosphorus gypsum slurry. |
