Jet Sand Suction Dredger

River sand is the preferred material for high-strength concrete. The Jet Sand Suction Dredger excels in non-consolidated sand deposits. By "blasting" the sand with high-pressure water, it creates a concentrated slurry cone at the intake. This process allows for the extraction of thousands of cubic meters of sand per month, providing a stable supply for local infrastructure and building projects.

Our factory-designed suction heads feature 4 to 8 high-velocity nozzles. This system fluidizes the sandbed instantly, ensuring the 250PNS or WN series pump always operates at its maximum solid-concentration capacity. This results in more "sand" and less "water" in every cubic meter pumped.

Sand is highly abrasive. To ensure long-term reliability, every part of the slurry path—from the suction intake to the pump impeller — is engineered for extreme wear resistance. This reduces the frequency of part replacements, keeping your Jet Sand Suction Dredger in the water longer.

FAQ

Q: Is a Jet Sand Suction Dredger better than a Cutter Suction Dredger for sand?

A: If the sand is loose and free-flowing, the Jet Sand Suction Dredger is more fuel-efficient and has lower maintenance costs. If the sand is trapped in hard clay layers, then a Cutter Suction Dredger is necessary to break the clay first.

Q: What is the maintenance cost compared to mechanical dredgers?

A: Because there are no submerged gearboxes or hydraulic cutter motors, the maintenance cost for a Jet Sand Suction Dredger is typically 40%-50% lower. Your primary wear parts are limited to the pump impeller and suction liners.

Q: Do you provide the sand-water separation equipment?

A: We provide the dredger and the pipeline. For on-shore separation, the slurry is typically discharged into a dewatering pond or a cyclone system. We can provide technical advice on setting up your sand-stockpile area for maximum efficiency.
