Centrifugal Heavy Duty Sand Suction Pump Horizontal Cantilevered Single Casing
Product Introduction od dredge pump
1. The sand pump impeller and casing are all made of high chrome alloy (Cr26 material) with anti-wear,anti-abrasive and longer life features.
2. Large capacity and high pressure.
3.The sand pump widely used in sand and gravel dredging, and all kinds of mining plant, such as gold mining, tin mining, scoria mining and so on.
Features
1. This pump is of horizontal cantilevered single-casing
centrifugal pump.
2. Construction of this pump is of single casing connected by means
of clamp bands and the discharge direction of pump can be oriented
in any direction of 360. the type of pump possesses the advantages
of easy installation.
3. The cylinder –type bearing assembly with oil lubrication is
adopted by the pump. It is suit for adjusting the distance between
impeller and pump. The bearing assembly uses oil lubrication.
4. Three kinds of shaft seal---mechanical seal, expeller seal and
packing seal
5. Wide passage , good performance of NPSH, anti-wearing and
anti-corrosion, and high efficiency,
6. The type of driver just have v belt driver, gearbox driver, elastic coupling driver, fluid couplings driver, frequency conversion driver, silicon controlled rectifier speed regulation etc.
Dredge Pump Materials:
Pump Impeller, Casing are made by High chrome metal alloy material, such as A05 or A61 which are
a high hardness and long service life.
