10/8 G Type Sand Suction Pump Cr26 Cr27 Cr28 High Chrome Cast Iron
Abrasive-Resistant Sand Pump Parts
Introduction
Sand pumps are cantilevered, horizontal, centrifugal slurry pumps
which do heavy duty. They are designed for transferring the highly
abrasive or corrosive slurry, high density slurry; they are popular
in the metallurgical, mining, coal, power station, sea water river
water & channel dredging, building material and other industrial
departments. The wet parts of slurry pump is made of high chromium
alloy, or abrasive rubber so they are suitable for the liquid with
solid, and with acid or alkali, this make the slurry pump powerful
and widely used. The pumps of this type can be driven by Electrical
motor or by diesel engine or by hydraulic power. The discharge of
pump can be in eight positions to suit installations and
applications. The shaft seals can be adoptable of gland seal or
expeller seal, or mechanical seal.
Pump cover for pressure parts, use nodular cast iron; Impeller and
volute, guard board, pump body as high hardness, wear resistance
cast steel. Connection parts adopt bolt or screw connection, for
rubber seal "O" type circle
Impeller
The impeller generally has three vanes or five vanes and wide
application range. It is made of 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 inspeed according to the pitch diameter of
thread. Disassembly rings are installed at the rear of the shaft
sleeve to make maintenance easy.
Pump casing
The pump casing is made of wear-resistant and compression-resistant
alloy (hardness>56HRC, impact toughness>8 j/cm2). Advanced
smelting guarantees smooth easting surfaces and reliable internal
quality.
The bulge test will be carried out after molding, and the test
pressure is 2 times of the discharge pressure of the pump. If there
is no leakage after 20 minutes, strength and tightness pressure
test reports can be issued.
Liner plate
The liner plates are made of wear-resistant high chromium alloy
cast iron (hardness > 56HRC, impact toughness>8 j/cm2).
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.
