14/12 ST - G (300 WS) Sand extraction pump and sand mud suction pump for dredging machine


WS dredging pump is a new type of sludge pump researched &manufactured by our company,based on advanced technique introduced ,aiming at the dredging pump and damming of the river and seas.It is widely agreed upon adopting dredging pump as main pumping equipement judging from the practice of treating rivers & seas at home and abroad .The means is consider to be a treatment of no-pollution to environment protection ,high efficiency and energy -saving .WS 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 mutiple economy benefits and so on .It throghout meets requirements of the dredge to dredging pumps.

The pump mainly consists of the pump head,gearbox specially for the dredging pump,high elastic coupling and supervisor system of the driving device for the dredge.

Strongly wear-resistant casting alloy iron,whose hardness is not less than 58HRC adopted for the impeller ,front liner ,and rear liner of wet parts .Wear -resistant alloy steel is adopted for the casting with pressure-wear-resistant.

Our company can select different kinds of material according to different media to meet the dredging requirements.

Construction & Features:

1.Advanced hydraulic model,CAD 3-dimension design,high efficiency and obvious energy-saving.

2.Large dredging depth,high density of dredging mud,good NPSH and stronger suction lift ability.

3.Strong through-put.The pump can persistently discharge gravel,high plastic soil lump and so on.

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 every kind 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 disassembly & assembly,convenient maintaining.

10.Reliable sealing without leakage.
