River sand suction dredger pump with anti-abrasive material and large flow rate capacity for gravel dredging
Construction
200WN to 500WN dredge pumps are of single casing, single stage cantilevered horizontal centrifugal pumps. Two types of coupling with gear box: frame and pump box.
600WN to 1000WN dredge pumps are of double casings, single stage cantilevered centrifugal pumps. These pumps are equipped with frame and lubrication is force thin oil. The design of double casing the pump working till the volute liner almost worn down and guarantee no leakage when volute liner is worn down.
Easy Uninstallation & Convenient Maintenance
WN dredge pump is of front uninstallation construction to make uninstall easily and convenient maintenance. And special tools are equipped for uninstalling the parts.
Standard four-head trapezoid thread connection between impeller and shaft can transfer powerful torsion and be convenient to uninstall. Impeller uninstall ring at shaft sleeve side also make the impeller uninstallation much easier.
Good Performance
Good NPSH can not only guarantee suction but also make deep dredge and high allowable suction density. Minimum NPSH: 4m.
With wide impeller passage, pump can continuously pump gravel or high plastic clay without clogging. Max allow particle size: 350mm.
Performance curves descend obviously to make pumps adopt pipeline distance changes.
By changing the impeller diameter or impeller rotating speed, it can easily change the discharge with the same flow rate.
Material
Material of wet parts is high wear resistant high chrome alloy.
Considering the maintenance, wear resistant parts are nearly of the same wear life to reduce maintenance & interchange costs.
Low Hydraulic loss, High efficiency, Energy Saving
Efficiency of WN is 2 or 3 percentage higher than other common pumps.
Reliable Shaft Seal, No leakage
Shaft Seal types of 200WN to 500WN: Mechanical seal, packing, or combination of mechanical and packing
600WN to 1000WN uses helical casing L rubber seal which is made of 3 pieces of L seal ring and one special thread shaft sleeve.
Turning
700WN to 1000WN can be equipped with turning to change rotating directions.
| 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 presistently 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 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 constrution, easily disassembly & assembly,convenient maintaince |
| 10. Reliable sealing without leakage |
| 11. Long operating life of parts |
