WN Series Hydraulic Open / Closed Impeller Sand Dredge Slurry Pump For River
Product Introduction of dredge pump
WN(Q) series are specially designed for mud,sand dredging application in river or sea.Robust structure design with front disassemble way guarantee its extra longwork life and easily maintenance.
300WN(Q)~500WN(Q) apply single shell
structure and 600WN(Q)~1000WN(Q)double shell structure to satisfy heavy duty dredging work.High chrome alloy made linerspares with a hardness 60HRC could standsevere bear and tear.
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 persistently 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 conditions.
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 constrution, easily disassembly & assembly,convenient maintenance
10. Reliable sealing without leakage
11. Long operating life of parts
