Dredge Pump
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.
Kingda dredge pump has good cavitation performance and strong flow capacity. It can continuously pump gravel or high plastic clay without clogging.
KINGDA Dredge Pump Applications
Kingda uses 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.
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.
Port dredging, river widening, tunnel sludge removal, mine tailings, petrochemical industry, dredger sediment mining, environmental protection
Kingda dredge pump adopts wide flow channel design, which can pass large particles with a diameter of 1-15.75 inches (0-400mm), so that Kingda dredge pump will not be clogged, which will greatly reduce downtime and maintenance costs.
Based on the non-clogging and strong impact resistance of Kingda dredge pump, dredge pump can pump most fluids, such as gravel, sand, aggregate, hard clay, rock, mud, rotten plants, mud, silt, riverbed sediments, tailings.
Dredging refers to the use of dredgers or other mechanical equipment to dredge dams, build ports and canals, remove sediments from lakes and rivers, deepen and widen waterways, and maintain coastlines and protect the natural environment.
The dredging process is generally divided into three stages: sludge suction, sludge delivery, and sludge unloading.
During dredging, the dredger uses a mechanical arm to push the suction cup with a cutter head deep into the bottom of the lake. The rotating cutter head cuts the sediments on the bottom of the lake and transports them to the dredger through a delivery pipeline, or the dredging pump pumps the sediments to the shore.
Kingda Dredge Pumps
Kingda dredge pump can not only pump abrasive slurry containing large solids, but also pump corrosive and high-viscosity slurry. Its wide blade and wide flow channel design ensure that the dredge pump will not be clogged.
WN Dredge Pump
WN series dredge pumps can be used not only in the cabin of the dredger, but also underwater.
The maximum solid diameter that can be passed is 15.75 inches (400mm). The dredge pump can continuously pump gravel or clay without clogging.
Small Dredge Pump
Small dredge pump is light and easy to install. It adopts widened flow channel design, which can continuously transport large particles of highly abrasive mud and sand.

features and benefits
Strong wear resistance
The wet end parts, impeller, sleeve, front and rear plate liners (wear-resistant lining) of Kingda dredge pump are made of high-strength wear-resistant alloy. While having strong impact resistance, it also has a high degree of abrasion resistance. In the process of product design, the service life matching between parts is fully considered, and the replacement cycle of wear-resistant parts is basically the same, which reduces the cost of maintenance and replacement.
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.

and design
The CFD Analysis Technology
Based on The Multi-phase Flow
Applying CFD technology to analyze and calculate the velocity and pressure fields inside slurry pumps, predicting performance parameters and optimizing designs. This includes researching multiphase flow characteristics, particle wear features, and their impact on pump efficiency, enabling the series expansion of hydraulic models.
Analysis of strength and
optimal desigh
Using finite element analysis, we calculate the stress distribution in both circumferential and radial directions within the volute under various operating conditions (including stable operation, start/stop, and variable conditions).
The goal is to identify the maximum stress points and perform strength validation. This ensures that the component’s rigidity and strength meet the requirements while reducing design redundancy.
CAE Technology for casting
CAE technology simulates the entire pouring process, analyzing temperature, flow, and stress fields. This helps predict defects like shrinkage and porosity, enabling process optimization and improved product quality.
By simulating thermal and mechanical stresses, CAE ensures slurry pump components can withstand harsh conditions, improving material selection and durability for longer pump life and minimizing shrinkage and porosity, resulting in stronger, more reliable slurry pumps with fewer maintenance needs.
Continuous simulations refine casting and design processes, enabling ongoing improvements in slurry pump performance and quality across industries.
Desigh of 3D Model
Slurry pumps and spare parts are designed using 3D models, ensuring optimized functionality, aesthetic appeal, and ease of maintenance.
3D models ensure precise fit and function of spare parts, reducing errors and production adjustments, leading to better efficiency, and helping identify potential issues in installation and operation early, ensuring smooth deployment and reducing field problems.
3D models optimize pump components for better performance, easier maintenance, and longer service life, reducing wear and increasing energy efficiency.

FAQ about Dredge Pump
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.
