SMWN500 Dredging Pump

SMWN500 Dredging Pump

•      Product Introduction

We are the leading sand pump and sand dredger solutions manufacturer, supplier and exporter and have more than 10 years experience on supplying the whole solution from designing to technical support according to your specific working condition. SMWN500 dredging pump is a500mmsize single casing sand dredge pump. These WN series dredge slurry pumps have super strong excavation and suction ability. According to the connecting way of gear box can provide two kinds of typical structures, one is connected with own bearing bracket, the other is combined with a reduction gear box. The lubrication of pump with bearing bracket is grease lubrication or thin oil lubrication. It is single-stage, single-suction, cantilever, horizontal centrifugal slurry pump. The pump is marine dredging pump for dredging of river and sea. The flow passage of the impeller is wide through the capacity, so it is difficult to block for pumping sand gravel or high plastic clay. This pump is simple and reliable in structure, easy to disassemble and maintain, and adopts high chromium wear-resistant alloy material, which has a long trouble-free life. It is suitable for dredging and filling operations of cutter-suction dredger and trailing suction dredger. It is also used as river gravel sand pump and mine slurry pump in vessels.

•      Model meaning:  For example: SMWNS600 (WN: WN series Dredge Pump; S: Submersible Pump; 600: Discharge Diameter (mm).)

•     Product Feature

1. Adopted advanced hydraulic model, the pump has low hydraulic loss, high efficiency and low energy consumption. The service life of each part is fully considered in the process of product design. The same replacement cycle reduces the maintenance and replacement costs.

2. The structure is simple and reliable.

The pump adopts single pump casing structure, in order lower the pump weight, easy to lift and move.

3. Easy to assemble and disassemble and easy to maintain. The front dismantling structure is adopted, and special disassembly tools are equipped to facilitate disassembly and assembly.

4. The performance of dredging is excellent. The flow and head curve of the pump is steep, the suction ability is strong, the ability of passing the pump is good, the change of the distance is more applicable, and the depth of digging and the higher transportation concentration can be reached.

5. Excellent wear resistance and long life of wet parts. The metal spare parts are made of strong wear resistant alloy cast iron whose hardness is not less than 58HRC. It has not only impacted on resistance but also high anti-abrasion performance.

6. The shaft seal is reliable and no leakage.

The pump adopts mechanical seals or packing seals or a combination of mechanical and packing seals.
