River Jet Suction Dredger

In natural river systems, sand is often loose but deep. The River Jet Suction Dredger excels by using high-velocity nozzles to "boil" the sand bed. This fluidization allows for a constant, high-concentration feed to the 250PNS or WN series pump, achieving a solid productivity of 120m³/h to 400m³/h. It is the most cost-effective tool for supplying high-quality construction sand to local markets.

Seasonal floods often create new sandbars that obstruct navigation. Our River Jet Suction Dredgers feature a compact modular design and a shallow draught (0.5m-1.2m). This allows the vessel to climb onto shallow bars and "wash them away" from the inside out, restoring the river's cross-sectional area and preventing upstream flooding.

River water entering a reservoir often drops its sediment load at the intake. The River Jet Suction Dredger provides a "Clean Extraction" method. Without a rotating cutter, it minimizes the disturbance to the surrounding aquatic habitat while effectively clearing the silt that threatens dam intake pipes and hydroelectric turbines.

FAQ

Q: Can a River Jet Suction Dredger handle hard clay or rock?

A: This model is optimized for non-consolidated materials like sand, gravel, and silt. If your riverbed has a thick layer of hard-packed clay or rock, we recommend our Cutter Suction Dredger series which provides mechanical breaking force.

Q: What is the maximum discharge distance for this river model?

A: Depending on the engine and pump configuration, our River Jet Suction Dredgers can push slurry through 500m to 1500m of HDPE pipeline. For longer distances, we can provide a customized high-head pump or a portable booster station.

Q: Is the vessel easy to transport past low bridges or dams?

A: Absolutely. Every River Jet Suction Dredger features a Bolt-on Modular Design. The ship is easily disassembled into sections that fit on standard flat-bed trucks or in 40ft containers, allowing you to bypass river obstacles and reassemble on-site in less than 10 days.
