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. |
