•      Product Introduction

Our WN series dredge slurry pumps are simple and reliable, easy to disassemble and maintain, have super strong excavation and suction ability. This SMWN300 dredging pump is one of them, which is a single-suction, single-stage, single casing, cantilever, horizontal centrifugal slurry pump. The wet ends of this sand dredge pump are made of high chromium wear-resistant alloy material, which gives the pump long trouble-free life. It is marine dredging sand suction pump for dredging of river and sea. 

•     Model meaning:  For example: SMWNS300 (WN: WN series Dredge Pump; S: Submersible Pump; 300: Discharge Diameter (mm).)

•     Product Feature

1. Smooth flow channel, good anti-blocking performance, excellent cavitation performance.

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 metal spare 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.

5. Using advanced hydraulic model, this sand suction 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 reduce the maintenance and replacement costs.

6. The shaft seal is reliable and no leakage.

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