Gravel Dredger Pump includes Dredge Slurry Pump , Gravel Pump , Sludge Dredge Mining Pump, Dredge Gravel Slurry Pump, Gravel Sand Pump , Dredging Pump , Dredge Pump Sand Mining Pump, River Sand Suction Dredge Pump, discharge pump for pipe jacking. Gravel Pump  is a single stage, single suction, cantilever,horizontal structure ,The dredging pump structure is divided into two kinds of structure according to the size of pressure discharging, ie single and double pump casing;According to the driving type ,it can be divided into two kinds of typical structures, one type is with self-bracket,another one type is with pump and gearbox together (i.e.,gear box ,motor as a whole) self-bracket type lubrication type has two types of lubrication ,grease or oil lubrication .
Application: This pump is used for dredging in river, mining in deep-sea, desilting in reservoir and reclamation by pump filling along the coast.

WN series dredge pump is my company developed a large of mud pump. Light weight, wear resistance, superior performance dredging and so on. 

Function Introduction:
1. This pump is of horizontal cantilevered single-casing centrifugal pump. 
2. Construction of this pump is of single casing connected by means of clamp bands and the discharge direction of pump can be oriented in any direction of 360. the type of pump possesses the advantages of easy installation. 
3. The cylinder –type bearing assembly with oil lubrication is adopted by the pump. It is suit for adjusting the distance between impeller and pump. The bearing assembly uses oil lubrication.
4. Three kinds of shaft seal---mechanical seal, expeller seal and packing seal 
5. Wide passage , good performance of NPSH, anti-wearing and anti-corrosion, and high efficiency,
6. The type of driver just have v belt driver, gearbox driver, elastic coupling driver, fluid couplings driver, frequency conversion driver, silicon controlled rectifier speed regulation etc.

Our dredging pumps are widely used to dredge and dam in the rivers, ports and wharf over our country, such as Yangtze river , The Yellow River , Liao River, and Zhujiang Delta. Besides, sold to Europe, Middle East and Southeast Asia. CCS (China Classification Society) has inspected each set.
