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.

1 Ws Dredging Pump is a new type of sludge pump reseached and manufatured by our factory aiming at the dredging and damming of the river and seas.
2. The means is consider to be a treatment of no -pollution to environmental protection, high efficiency and energy-saving 
3.Light weight, good wear-resistant, super dredging performance 
4.Our Company can select different kinds of material according to different media to meet the dredging requirement.

200 WN - 500 WN type dredge pump integral by a single pump shell, single stage single suction cantilever horizontal structure, press and gear box of the connection way all can provide two kinds of typical structure, namely take bracket type and pump box and type. Own bracket type lubrication way as the grease lubrication or thin oil lubrication.

600 WN - 1000 WN type dredge pump overall adopts double pump shell, single stage single suction cantilever horizontal structure, bring their own bracket, lubrication way as the forced thin oil lubrication. Double pump shell the safety and reliability of the design makes sheath always can use to close to wear through, and when sheath rupture, pump room will not fill.
 

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

 

Applications:

Dredging industries

Hydraulic Mud Fill
