Detailed Product Description

         NS series multi-purpose sand pump

1.Product Introduction:

The multi-purpose sludge pump is single-stage single-suction centrifugal pump, and comprises several series and various specifications such as 500mm, 450mm, 400mm, 350mm, 300mm, 250mm, 200mm,150mm and so on according to outlet diameter. The pump is innovative in hydraulic design and structural design, and adopts the overflowing part cast by strong abrasion-resistant high chromium wear-resistant alloy, so the pump has the characteristics of high efficiency, energy conservation, wear resistance, reliable operation and so on. The blade number of the impeller of the pump can be changed according to different working conditions; and the pump is suitable for conveying strong-abrasion mortar, tailing slurry, slag and so on containing big and small solid particles. The maximum mixture concentration of conveyed powdery is up to 60%. Therefore, the pump is ideal sand pumping and conveying equipment and users can select single machine or multiple serially-connected machines to achieve the aim of long-distance conveying according to actual working conditions.
The pump can be equipped with different diesel engine unit, generator system and big or small pumps of different models according to different users requirements.

2.Structural Property

  (1).The pump body adopts a two-layer metal structure with an inner layer and an outer layer; the pump shell is vertically opened in the middle; and the water outlets are rotationally installed at 45 degree intervals.
(2).The proper shaft seal can be selected such as auxiliary impeller shaft seal, packing shaft seal and mechanical seal according to different working conditions.
(3).The pump adopts closed impeller, so the pump has good wear resistance and high pump efficiency.
(4).The pump can convey mixture containing few big particles through adjusting the blade number and the impeller diameter.

  3.Application

 The pump is widely applied to sand pumping from river channels and reservoirs, exploiting seashore, conveying electric fly ash and conveying tails in the metallurgical industry, etc.
