Gravel pump for sand dredging

Pump overview

Dredging pump is a single-stage single suction cantilever horizontal centrifugal pump with advantages of light weight, good wear-resistant, super dredging performance, perfectly suited for the dredge on the whole construction, high multiple economy benefits, etc.

Pump features

1. Advanced hydraulic model, CAD 3D design, high efficiency and obvious energy-saving 2. Large dredging depth, high density of dredging mud, good NPSH and strong suction lift ability 3. Strong through-put. The pump can presistently discharge gravel, high plastic soil lump,etc. 4. The pump can be directly matched with either motor or diesel engine 5. Wide application. It can be used in various kinds of soil quality. Generally, the pump is matched with an impeller with 3 or 5 pieces of vane. At the same time, the impellers can be provided with various diameters and vane types to suit kinds of working condition. 6. Little hydraulic loss, high efficiency and low oil-consumption 7. Little volume, light weight 8. Steady operating, little vibration, low noise 9. Simple & reliable construction, easily dis-assembly & assembly,convenient maintain 10.Reliable sealing without leakage 11.Long operating life of parts

Pump application

1.The ZN sand pumps are designed for continuously handling the most difficult higher abrasive slurri es which contain too big solids to be pumped by a common pump. Such as dredging, suck gravel in the dredger, suck gravel in the course of rivers or lakes,delivering slurries in mining, explosive sludge in metal smelting.( Type ZNH pumps are of high-head ones ) 2. ZN dredge pumps are widely used to dredger and dam in the rivers, ports and wharf over our countr y, such as Changjiang River, Huanghe River, Liao River, and Zhujiang Delta. And also widely used abroad,such as Middle East,Europe,etc.
