Dredge Pump
Kingda dredge pump can calmly cope with harsh dredging environments. Its special large-gap hydraulic design and anti-clogging channel ensure that no clogging will occur.
We offer sand dredge pumps, submersible dredge pumps, electric dredge pumps, and small dredge pumps — providing you with the most comprehensive dredging solutions to maximize your benefits.
Understanding Anti-Abrasive Dredge Pump
Dredge pumps are centrifugal pumps specifically designed for dredging operations. Dredge pumps are used on a dredger to extract materials such as gravel, sediment, biomass, and silt from the riverbed and place them in designated areas.
Dredging pumps are used in river dredging, port construction, mining, and ecological restoration projects, including river widening, island reclamation, and wetland restoration.
Dredge pumps typically exhibit excellent abrasion and clogging resistance, minimizing wear and tear on high-solids fluids and ensuring extended operation without downtime.
Kingda dredge pump adopts wide flow channel design, which can pass large particles with a diameter of 1-15.75 inches (0-400mm), so the pump will not be clogged, which will greatly reduce downtime and maintenance costs.
Based on the non-clogging and strong impact resistance of the Kingda dredge pump, the pump can pump most fluids, such as gravel, sand, aggregate, hard clay, rock, mud, rotten plants, mud, silt, riverbed sediments, tailings.
Where Our Dredge Pump Works – From Rivers to Mines
Kingda dredging pumps are widely used in dredging industry, for example, removing river bottom sediments, sand, gravel, silt, building ports and docks, maintaining coastline ecology, widening canals, conveying mine tailings, marine engineering, petroleum engineering, sewage and wastewater.
Dredge Pump Applications: Sand, Gravel, Slurry, and Beyond
🔸River Dredging: Dredge pumps can easily lift sediment and debris from the riverbed to shore, ensuring the widening of rivers and waterways.
🔸Port Construction: In port construction, dredge pumps can effectively pump sediment to designated locations, thereby accelerating construction progress.
🔸Island Reclamation: In today’s land scarcity, artificial island construction using dredging equipment is an inevitable trend.
🔸Ecological Restoration: Dredging equipment regularly removes debris and silt from lakebeds, maintaining coastlines and restoring the ecological balance of wetlands.
🔸Mining Slurry: In the mining industry, pumps can stably and long-distance transport solid-laden slurries and mining wastewater.

Dredging pump features and benefits
Strong wear resistance
The wet end parts, impeller and wear-resistant lining of dredge pump are made of high-strength wear-resistant alloy. While having strong impact resistance, it also has a high degree of abrasion resistance. When encountering gravel materials, it can minimize pump wear and extend its service life.
High efficiency and low power consumption
Dredge pump uses advanced hydraulic model and has very high efficiency. The speed of impeller can be adjusted according to demand to achieve the purpose of changing the head, which makes Kingda dredge pump 2%~3% more efficient than ordinary dredging pump. In this way, lower fuel consumption and electricity can be obtained at the same output.
Reliable shaft seal without leakage
The shaft seal of the dredging pump can be mechanical seal, packing seal or mechanical and packing composite seal. A spiral sleeve L-type rubber seal device is also available, which consists of 3 L-shaped sealing rings and a sleeve with special threads to ensure that no leakage occurs.
Electric turning mechanism
Kingda dredge pump can be equipped with an electric slewing mechanism, which can drive the pump shaft to achieve forward and reverse rotation, which not only saves the time of disassembling and assembling the impeller, but also reduces the workload of operators.
Dredging Pump Curve
Dredge Pump Materials Engineered for Maximum Lifespan
Kingda dredge pump is made of high chromium alloy material, which makes dredge pump extremely tough. When handling large gravel, rock, and hard clay, dredge pump will reduce the abrasion of materials on the pump body with strong impact resistance, greatly extending the service life.
Advanced casting and heat treatment processes to keep the chemical composition of metal materials at high hardness and high toughness. Kingda dredge pump’s high-quality materials can resist wear and corrosion from most fluids.

FAQ
The dredging pump uses strong suction to suck sand, clay, plants and other sediments from the bottom of the lake, river or ocean into the pump and discharge them into the hopper of the dredger or the shore through a pipeline.
The dredging pump is a centrifugal pump, which mainly sucks and discharges fluids through the action of centrifugal force.
Generating centrifugal force: The dredging pump generates centrifugal force through the rotation of the impeller, and the centrifugal force generates a strong suction at the pump inlet.
Suctioning mud: Through the suction of the dredging pump, the sediments at the bottom of the river are continuously sucked into the pump.
Discharging mud: Through the continuous rotation of the impeller, the mud in the dredging pump is pushed to the outlet of the pump, and the mud is transported to the hopper of the dredger through a pipeline.
After the continuous operation of the dredging pump, the sediments at the bottom of the lake will be continuously discharged.
Because sand is composed of fine gravel, it poses a great challenge to the wear resistance of the pump. If a pump is used to dredge sand, a gravel pump or a slurry pump should be the first choice. Gravel pumps have extremely strong wear resistance and can continuously transport sand without wear.
Through the suction of a gravel pump or a slurry pump, the mixture of sand and water at the bottom of the river can be pumped up and transported to a designated location.
Dredging pumps can suck gravel, rotten plants, crushed stones and other sediments at the bottom of the lake into the pump and discharge them to the designed location. Dredging pumps are widely used in dredging rivers, widening canals, building ports and maintaining coastlines.
Yes, electric dredge pumps can be powered by generators, but it's essential to ensure the generator has sufficient power to operate the pump properly.
Typically, in large dredging projects, electric dredge pumps are powered by heavy-duty diesel generators or land-based generators.
Horizontal electric dredge pumps operate stably and are suitable for high-flow-rate applications, typically used on land.
Submersible electric dredge pumps operate directly submerged in water, suitable for use in deep water or confined spaces, and can also be mounted on excavators or robotic arms.
Yes, VFD control can control pump capacity by adjusting the motor speed to change the pump's flow rate and pressure in real time.
Industrial electric dredge pumps typically operate on 50Hz-60Hz three-phase AC power and use VFD (Vehicle Dynamics Discharge) to control speed, adjust flow rate, and head.
Small to medium-sized electric dredge pumps usually use low voltage (380V-690V), while large-scale dredging projects require large dredging pumps, necessitating medium/high voltage (2.4 kV-4.16 kV+).
