Audited Supplier Sand dredging machine is suitable to deliver low density slurry for metallurgical, mining, coal and building material, the sand dredging machine can be used to extract a variety of fine sand in industrial and mining enterprises. The sand dredging machine has the characteristics of high efficiency, energy saving, wear resistance, corrosion resistance, reliable operation, high lift head, large flow (Max. mixed flow rate is up to 2000-5000m3/h), deep dredging depth (Max. dredging depth is up to 30m), long delivery distance(longest delivery distance is up to 2km). The power of sand dredging machine can be electric motor or diesel engine.
The shaft seal of sand dredging machine is packing seal. The high pressure flushing water is added to clean the packing chamber and ensure the normal operation of the heavy duty pump. The steering of sand dredging machine is counterclockwise in the inlet. The outlet of the sand dredging machine is on the right side of horizontal direction of the sand pump. The outlet can be adjusted within 360 degrees according to the requirement. The material of sand dredging machine casing can be cast iron, cast steel or alloy. The material of the impeller and guard plate can be cast iron, cast steel, wear-resistant alloy, or non-metal wear-resistant material. The users can choose different types according to the actual application.

Apply for sand suction and dredging, extracting mud for ship, marine reclamation land, wharf building electric power and metallurgical industry for conveying tailing, and in coal washing industry for filtering coal slime.
On November 5th, 2021, our customer from Malaysia sent us an inquiry about sand dredging machine. He wanted to purchase sand dredging machine mainly used for sedimentation tank dredging. He required to pump the sediment into the sedimentation tank. The size of sedimentation tank was 5 m* 6 m*3 m. He planed to finished the dredging task within one hour. The discharge distance was 200m, the height was 5m. After discussed with the customer, our engineer team selected 200PNS-300 sand dredging machine. At the same time, we recommended the customer 8 inch sand suction rubber hose and HDPE pipe. The customer had electric power near the work site, so we equipped the sand dredging machine with 55kw electric motor. In order to ensure the safety of the electric motor and easy operation, we attached a 75 KW frequency cabinet.
| Model | 200PNS-30 |
|---|---|
| Flow | 410m³/h |
| Head | 28m |
| Rotating speed | 730rpm |
| Power | 55kw |
| Discharge distance | 200m |
After accepted the sand dredging machine, our customer took videos for us. We helped him design the installation line. According to our design drawings, the customer finished the dredging task as planned. They were very pleased with the efficiency of our heavy duty sand dredging machine.
1.Material : Using the cast iron ,cast steel or high wear resistant and strong corrosion resistance chrome alloy to make the over -flow part .
2.Long-term bearing life .The bearing assembly is composed of large diameter shaft and short overhang.
3.with distinctive innovation in hydraulic and structural design.
4.Large dredging depth, high density of dredging mud, good NPSH (net positive suction head)and strong suction lift ability.
