Dredge pumps are one of the most robust equipment for moving material. Dredging utilizes these high-powered pumps to transfer solids and liquids through a pipeline over a set distance and often involves working in sensitive or harsh conditions. The dredge pumps are abrasive-resistant, making them ideal for grinding through rocks, sludge, sand, slurry, and many other objects.
Selecting the correct dredge system is critical for the success of a project. With decades of experience, DAE Pumps produces reliable dredge pumps that continuously transfer large solids with little mechanical downtime, and at affordable prices. The open impeller design and powerful suction of the DAE Pumps dredge pumps allow for easy passage of large solids. Thus, our dredge pumps lead the industry in durability and power.

The versatile cable-deployed and excavator dredge pumps are interchangeable and can be configured to your specific requirement accordingly.
Cable-Deployed Dredge Pumps
Cable-deployed dredge pumps are the preferred tools to dredge or pump material from waterways or to unload barges. These powerful pumps can reach depths of up to 100-ft in water and pump solids at distances of over a mile reaching a rate of up to 1000 cubic yards of material per hour.
Excavator Dredge Pumps
Excavator dredge pumps are a game-changer for small to medium scale dredging projects. Hydraulic or electric excavator mounted dredge pumps allow contractors to perform their dredging by mounting a 4-inch to 16-inch pump on the end of an excavator boom. As a result, they can move large amounts of material up to 12,000 GPM with heads up to 400 feet.
Pontoon Dredge Pumps
Small pontoon dredge pumps or mini dredges are ideal for lagoons, basins, ponds, and other smaller dredging projects. Their robust and simple design allows a single operator to run a dredge remotely and most importantly, pump at the highest production rates without harming the poly, clay, or concrete liners.
Diver-Operated Dredges and Pumps
Diver-operated dredges and pumps get into areas where conventional dredging equipment cannot reach for removing large quantities of sediments and soils. Dredge around water intakes, wet-well, tanks, cooling towers, and other locations. Also use for wastewater treatment plants, dams, river terminals, power plants, paper/pulp mills, and other industrial facilities.
Dredge Pump Applications
DAE Pumps sand and gravel dredge pumps are ideal for a variety of applications, including dredging dams, ports, marinas, rivers, canals, lakes, ponds, and more. Ensuring water quality and capacity are essential in hydroelectric and water supply dams, therefore making the DAE Pumps dredge pumps perfect for removing excess sand, gravel, and silt. Clearing sediment and contaminates from riverbeds, channels, canals, and oceans help restore safe navigation and shoreline formations, and dredging lakes and ponds clean and remove contaminants and tailing. Primarily, as ocean currents move sediments, the seafloor slowly rises, lowering the depth of marinas and ports. Furthermore, rivers and streams also carry sediment and deposit it along banks. Dredging ensures safe access for boats and other water vessels.
Our dredge pumps are also used as barge pumps for offloading materials like mud and clay from maintenance dredging projects. Thusly, these barge pumps are attached to excavators on large pontoons and suction the material from the barges to a disposal area.

What is a Dredge Pump
A dredge pump is a heavy-duty centrifugal pump that moves sediment, sand, gravel, debris, and a variety of other solids from the surface floor through a pipe or hose to a discharge site. The dredge pump can handle abrasive granular materials and solids of various sizes and weights by putting them into suspension. As a result, the suspension of the material allow the solids to move through the pipeline. Dredge pumps move slurry, sand, sludge, and solids that most pumps cannot handle because of their design and the type of material they are made of.
There are many types, sizes, and powers of dredge pumps, but the intent of moving solids makes these powerful systems dredge pumps.
How does a Dredge Pump Work?
A dredge pump design is similar to other centrifugal pump designs. The core of the pump consists of an impeller, casing, and volute. Just as important to the pump is the motor. In addition, some pumps have agitators around the opening, side cutters, and jetting rings to help break up and disturbed the material for feeding the pump.
The impeller is mounted inside the pump casing and is attached to the drive motor via gearbox and shaft. The frontal portion of the pump casing is sealed using a suction cover, called the volute that connects directly to the dredge’s suction pipe. As the motor powers the impeller, the impeller spins. Because of specially designed ridges on the impeller, it creates a vacuum suction that draws in the materials and solids. Next, these solids are pushed through the opening to the volute and out the discharge. The separation between the impeller and volute opening limits the size of the solids. Finally, the dredge pump’s discharge is positioned near the top of the dredge pump and is connected to a separate discharge line. This discharge opening identifies the size of the pump.
To generate the power for lifting heavy rocks, sand, and other solids requires a powerful motor and a well-designed pump. Thus, more powerful motors with higher horsepower or kilowatts rotate the impeller faster and force more material higher and farther through the pipelines, allowing for higher heads. Likewise, this same principle occurs for larger-sized pumps designed to feed more material through at a time.
Parts of a Dredge Pump
- Impeller – Circular design with ridges to create suction force
- Casing – Encloses the pump and motor
- Volute – Directs the material through the pump to the discharge
- Motor – Powers the dredge pump
- Hose / Pipe – Is the vehicle for transferring the material
- Gear Box – Powered by the motor to turn mechanisms
- Shaft – The rod that spins the impeller
Typical Dredging Projects
Dredging is as essential today as it has ever been. The increase of technology, growth of cities, changing tides, and many other factors contribute to the need for more and more dredging projects. From large to small projects, dredging and the equipment used are becoming more sophisticated. Dredge pump’s capabilities are getting faster and better. DAE Pumps is here to help you with your next dredging project. Here are many common dredging projects our silt, sand, and gravel dredging pumps are used for:
