The key differentiator lies in its cutter-free jet suction mechanism. Instead of mechanical agitation, it relies on focused high-pressure water jets to loosen and suspend bottom sediments. A high-power suction pump then lifts the slurry in a continuous, residue-free operation. This method delivers powerful suction with no dead zones. With a flexible daily output of 300 to 8,000 cubic meters, the dredger adapts to varying project scales and water depths ranging from 0.3 to 12 meters.
Frequently Asked Questions
-
Q Can your Jet Suction Sand Dredger be customized?A Yes, we support OEM/ODM customization. We can customize the parameters such as tonnage, dredging depth and daily output according to your specific needs, and provide free design drawings.
-
Q What is the service life of the equipment?A The service life of the hull is 8–15 years, and the service life of wearing parts (cutter, impeller) is 2–3 years. We provide lifelong technical guidance and wearing parts supply.
-
Q Do you provide installation and after-sales service?A Yes, we provide 24/7 after-sales support. If there is any problem with the equipment, our technical team will arrive at the site for maintenance within 48 hours.
-
Q Can the equipment be used in sea water?A Yes, our Jet Suction Sand Dredger adopts anti-corrosion design, which can work stably in shallow sea salt water environments, and is suitable for offshore sand mining and sea area dredging.
-
Q What water depths is the Jet Suction Sand Dredger suitable for?A The dredger is designed to operate across a wide range of water depths, from as shallow as 0.3 meters up to 12 meters, making it versatile for rivers, reservoirs, ponds, and shallow coastal areas.
-
Q What makes the jet suction mechanism different from traditional cutter suction dredgers?A Unlike traditional cutter suction dredgers that rely on mechanical agitation, the jet suction mechanism uses focused high-pressure water jets to loosen and suspend bottom sediments. This results in a continuous, residue-free operation with no dead zones, lower maintenance requirements, and greater adaptability to varying sediment types.
