Audited Supplier Sand dredge slurry pump are the horizontal, single stage and double casing pump. The sand dredge slurry pump are innovative in the design of structure and hydraulic performance. Over-Flow components are made of abrasion resistant high chromium alloy. The sand dredge slurry pump has the characteristics of high efficiency, energy saving, wear-resisting and reliable running etc.
The sand dredge slurry pump can convey gravel, slurry or sand with the solid and liquid density up to 60%. The sand dredge slurry pump are suitable to convey strong erosion slurry, slag or grout contained solid particles. The sand dredge slurry pump are widely used in pumping sand, land reclamation, electric coal-ash and tailing in metallurgy industry, etc.

sand dredge slurry pump adopt double-pump case structure and is extensively used to extract medium particles such as mud, fine sand, tailing slag then carry them out to long distance destination.OCEAN pump DS series sand dredge slurry pump is suitable for mud conveying, sewage treatment, marine suction, sand extraction, land reclamation and dock construction, etc. The type of sand dredging pump can also be used in power plant, metallurgical transportation tailings, river dredging and other dredging industries. Our sand dredge slurry pump have been widely used in various conditions such as dredging and embankment in the Yellow River Basin, dredging in the Yangtze River Basin, land reclamation along the coast and sludge treatment.
Our US customer contacted us about their problems of sand dredging pump in April 2019. They are using a cutter suction dredger to get sand from lake and need a long distance transportation. But the current sand dredging pump equipped in the dredger is not enough to meet the transport requirements. So, they need to add a powerful high head sand dredge slurry pump .
Their transport requirements are as following:
After calculation, we proposed DS300-70 type sand dredging pump unit for customer. And supportin marine diesel engine and marine gear box of 600 type. This type of high head sand dredge slurry pump are equipped with five blades impeller, with advantage of high efficiency and low failure rate. The sand dredge slurry pump component in contact with the medium is made of high chromium alloy material. And the sand dredge slurry pump uses double shell structure which features stable, safe, high head discharge distance and very wear resistant. This sand dredge slurry pump are very suitable for customer's condition.
sand dredge slurry pump parameters for customer
| Model | DS300 - 70 |
| Capacity | 1800m³/h |
| Head | 49m |
| Rotate speed | 830r/m |
| Shaft power | 294.5kw |
| Specifications of the diesel engine | 559kw, 1800r/m |
| Gear box | Type 600 - 2:1 hydraulic marine gear box |
After communication, our customer agreed with the selection and matching of this sand dredge slurry pump , and placed orders in September 2019. Our factory arranged production and procurement actively, and prepared the goods within 20 working days for engine long delivery time.
At last, our customer arranged their representative come to test the sand dredge slurry pump unit. The detection contents are as follows :
Through this case, Ocean Pump products passed through the world's most stringent testing which marking our products and supporting forces have been recognized by the developed countries. And that laid a good foundation for the future exporting of our main pump to Europe and America.
1.The high head sand dredge slurry pump have the excellent water performance, high efficient and low wear rate with the help of CAD design and CAE simulation.
2.Smooth flow channel, good anti-blocking performance, excellent cavitation performance.
3. Vice impeller seal, packing seal or the mechanical seal to ensure no slurry leakage. Reliable design can ensure the sand dredge slurry pump work with long time.
4. Adopt the thin oil lubrication metric bearings with reasonable set of lubrication. Cooling system to ensure that the bearings run at low temperature.
5. With special treatment, the sand dredge slurry pump can be used the corrosion working conditions like seawater ash ,seawater and salt spray.
6.Within the allowable pressure range, the sand dredge slurry pump can be used in multiple stages series connection .with allows maximum working pressure for 3.6Mpa.
