SMWN250 Dredging Pump

SMWN250 Dredging Pump

•   Product Introduction

WN series dredge slurry pumps built from high chrome hard metal castings are ideal for transporting large particle slurries, have super strong excavation and suction ability.SMWN250 dredging pump is a cantilever horizontal centrifugal slurry pump, which is simple and reliable, easy to disassemble and maintain, has a long trouble-free life. This sand centrifugal slurry pump is a marine dredging pump for dredging of river and sea. The flow passage of the impeller is wide, so it is difficult to block for pumping sand gravel or high plastic clay. It is suitable for dredging and filling operations of cutter-suction dredger and trailing suction dredger. 

•   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.

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

3. 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.

4. The shaft seal is reliable and no leakage.

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

5. 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.

6. 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.
