What Kind of Suction Dredge Pumps are Suitable for Inland River Dredging

What kind of suction dredge pumps are suitable for inland river dredging? Followed are some suggestions.

Inland river is different from large river and sea. There are large particles or twining solids such as mixed garbages, weed, bricks; Mud is more than sand, it may dry up in summer.

At present, cutter suction dredgers is often equipped with suction dredge pumps and vertical sand pump units, the cutter suction dredgers can be used with excavator ships for inland river dredging. Besides this, there are other methods for inland river dredging.

1. For a dry river, there is no water source nearby, excavator or artificial way is suitable but not sand pump. This method is time-consuming and laborious. The working efficiency is lower.

2. The river water is very shallow. Vertical suction dredge pumps equipped with high pressure water gun are a better choice. It has the features of easy operation, high suction concentration, high efficiency, thorough cleaning up. The disadvantages are that it needs manual operation and the discharge distance is not so long.  If the conveying distance is long, horizontal suction dredge pumps can be used as booster pumps. The sand extracted by several vertical suction dredge pumps gathers to one horizontal sand pump, then is conveyed to discharge destination.

3. When the river has sufficient water supply, a variety of sand pumping equipment can be used in conjunction with each other. If there are a lot of weeds in the river, the mowing boat can clean up the weeds at first, then the cutter suction dredger cleaning up sediment and stones. The big particle gravel sand pumps are suitable to be equipped on the cutter suction dredgers, because the large particle suction dredge pumps have the characteristics of wide channel, non blockage, strong wear resistance. The largest particle diameter allowed to pass is 20cm, it is the best choice for this working condition.

Generally, the river clearing project is more complicated, we can choose the suction dredge pumps according to actual working condition.
