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).
