SMWN600 Dredging Pump

SMWN600 Dredging Pump

•      Product Introduction

SMWN600 dredging pump is innovative in the design of structure and hydraulic performance. Metal spare parts of it are made of abrasion resistant high-chromium alloy, with characteristics of high efficiency, wear-resisting and reliable running etc. It is single-stage, single-suction, cantilever, horizontal 600mm size double-shell inboard dredging pump. Its gear box is connected with own bearing bracket. Lubrication way is mandatory thin oil lubrication. SMWN600 is marine sand dredger pump for dredging of river and sea. It is suitable for dredging and filling operations of cutter-suction dredger and trailing suction dredger. It is also as sand suction dredge pump for river sand mining and mining vessels.

• •    Product Feature 

1.   The structure is simple and reliable.

The pump adopts double  casing structure, with its own bracket. The safety and reliability of the double pump casing design keeps the volute liner can be used to close to wear out, and when the liner was broken, no water will enter the pump room.

2. 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.

3. 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.

4. Excellent wear resistance and long life of flow wear parts. The impeller, volute liner, throat bushing and rear plate liner (wearable liner) are made of tough 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.

5. 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.

6. The shaft seal is reliable and no leakage.

The shaft seals adopt screw shaft sleeve with L-shaped rubber seal device, which consists of three L-shaped seal rings and one threaded shaft sleeve.
