SMWNS500 Dredging Pump

SMWNS500  Dredging Pump

•      Product Introduction

SMWNS500 dredging pump with a single casing is a single stage, single suction, cantilever, horizontal slurry pump. This WN series dredge slurry pump is driven by the variable-frequency motor via the gearbox. The submerge slurry pump an realize the variable-speed performance at multi working condition points with the fine self-priming, wear resistance, smooth operation, low noise and convenience for overhaul and hoisting. 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 reduction gear box. The sand dredge pump is equipped with the self-supply gland water system with sand filter and lubricating system and has a long service life and durability. SMWNS500 dredge ash slurry pump is suitable for dredging and filling operations of cutter-suction dredger and trailing suction dredger. It is also used as river sand dredger pump and mine slurry pump in vessels.

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

1. The structure is simple and reliable.

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

 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 wet parts. The impeller, volute liner, throat bushing and rear plate liner (wearable liner) 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.

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