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.
Model

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.
