Introduction:
Naipu® NP-WSdredging pump is 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 and so on .It throughout meets requirements of the dredge to dredging pumps .The pump mainly consists of the pump head , gearbox specifically for the dredging pump ,high elastic coupling and supervisor system of the driving device for the dredge.
Features:
a) Advanced hydraulic model, CAD 3D design, high efficiency and obvious energy-saving
b) Large dredging depth, high density of dredging mud, good NPSH and strong suction lift ability
c) Strong through-put. The pump can presistently discharge gravel, high plastic soil lump,etc.
d) The pump can be directly matched with either motor or diesel engine
e) 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.
f) Little hydraulic loss, high efficiency and low oil-consumption
g) Little volume, light weight
h) Steady operating, little vibration, low noise
i) Simple & reliable constrution, easily disassembly & assembly,convenient maintainance
j) Reliable sealing without leakage
k) Long operating life of parts
l) Long operating life of parts
