Portable large particle dredger is widely used to excavate underwater sediments and widening from river, shallow seas or freshwater areas, or to keep waterways navigable and create an anti sludge pathway for boats. Generally speaking, portable dredger is easy to be installed and operated, so it is popular with foreign customers. But if a set of gravel pump is equipped on the portable dredger, it becomes portable large particle dredger, besides the features of easy installation and operation, the new type portable large particle dredger can achieve longer discharge distance and bigger diameter of overflowing particles.
German customers visited us for the portable large particle dredger on 27th November, 2018. We acompanied them to our factory for the sand pump and sand dredger, we showed them different kinds of sand pumps, slurry pumps, water pumps, dredgers, spare parts, pipes and hoses and Introduced the features and applications of every type. Because of hot interests in our dredging products they took many photos of our dredging machines. Then we talked about technical matters when we went back to office. After communication and discussion, our engineers recommended the gravel pump to use on their customized dredger, and chose one high pressure water pump according to their working condition. we also supplied technical details and catalog for them.
The customers ordered the portable large particle dredger for a port dredging project in Cuba for cleaning and improvement. The dredge depth is within 5m and the discharge distance is up to 300m, the sand output is over 110 m3/h, the lift height is not more than 2 m, the sand is very coarse with some broken seashell and mixed with some small storm about 30-40 cm. The simple sand dredging machine ever applied for sand pumping is not enough for their business, so they came to Ocean Pump for better sand dredging machine solution.
We are very professional with this working condition since we have served several similar customers’ working site conditions before. During communication, the customers indicated that they were afraid of the unbalance caused by sea wave to sink the dredger boat, so we recommended to add the side pontoons on the basis of the original plan. The 6 inch portable large particle dredger with 2 extra pontoons for balance were better solution for their usage. We also recommended spare parts and the large diameter discharge pipeline for the sand dredger, some rubber hoses intervals with discharge pipe is also configured to stand up storms.
The technical parameters of the 6 inch portable large particle dredger:
| Sand pump | 6 inch gravel pump |
| Diesel engine power | 90kw |
| Suction depth | 5m |
| Solid sand capacity | 35-55m³/h |
| Discharge distance | 300m |
Finally, they ordered the 6 inch gravel suction dredger equipped with the wear resistant gravel sand pump set and powerful diesel engine.
