6 / 4 D - small metal centrifugal slurry pump for the mining
industry
Introduction:
Solutions for the most abrasive slurry applications:
With high-performance wear resistance, the SME SH pump family
withstands the most severe slurry applications.
The SH Pump family is recommended for applications with coarse or
fine particles from solids-laden waste to aggressive slurries of an
abrasive nature.
SH rugged design features, combined with casing, impeller, and
liner in our proprietary A05 material, are recognized worldwide for
superior abrasion resistance. In addition, several impeller options
to fine-tune pump performance, and customized pumping needs are
available. These options allow optimum wear life and sustained
efficiency.
Components:
Impeller
The impeller, either elastomer, stainless steel or high-chrome
material, is the main rotating component that normally has vanes to
impart the centrifugal force to the liquid.
Casing
Split outer casing halves of cast contain the wear liners and
provide high operation pressure capabilities. The casing shape is
generally of semi-volute or concentric, efficiencies of which are
less than that of the volute type.
Shaft and Bearing Assembly
A large diameter shaft with a short overhang minimizes deflection
and vibration. The heavy-duty roller bearing is housed in a
removable bearing cartridge.
Shaft sleeve
A hardened, heavy-duty corrosion-resistant sleeve with O-ring seals
at both ends protects the shaft. A split fit allows the sleeve
removed or installed quickly.
Shaft Seal
Expeller drive seal, Packing seal, Mechanical seal.
Drive Type
V-belt drive, gear reducer drive, fluid coupling drive, and
frequency conversion drive devices.
Typical Applications:
Sand and Gravel
Hydraulic Mining
Sugar Beet & Other Root Vegetables
Slag Granulation
Tunneling
Material: High Chrome Alloy A05
