8/6E River Sand Gravel Dredging Pump Flux Parts Replacements Hard
Metal A05, A07 OEM Sand Pump Parts
Main parts:
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).
