Dredging Pump Use Flux Parts Replacements High Chrome Cast Iron
Anti-Abrasive Long Life Sand Pump Parts
Sand Gravel Pump Introduction:
1. Sand pump (dredge pump) is designed as single casing connected
by means of clamp bands and wide wet-passage.
2. The wearing parts are made of ultra chromium abrasion-resistance
alloys, long service life and very low failure rate.
3.The pumps are designed for continuously transferring strong
corrosive big-solid -contained slurry which the
common slurry pump cannot transfer. They are widely used in
dredging,sand excavation;mining,
explosive-sludge in metal melting, etc.
Pump cover
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).
Suction mouth
The Suction mouth is the important part of the mud pump. It is made
of wear-resistant high chromium alloy cast iron.
(hardness>58HRC, impact toughness >9 j/cm2 )
Suction ring
The suction rings are made of wear-resistant high chromium alloy
cast iron (hardness>56HRC, impact toughness>8 j/cm2).

Product Features:
1. Wear parts are constructed with chromium alloy; so pumps have
better stability & longer service life.
2. Unique mechanical seal device can protect the electric motor and
ensure high suction efficiency.
3. Additional agitation impeller is equipped to help break and mix
the sludge.
4. Easy installation, operation and cost saving, since no extra
vacuum pump or pump house is needed.
5. Professional technology support is provided during the whole
process of the usage and maintenance.
