An excavator dredge pump is a hydraulic-driven excavator attachment designed to extract and transport underwater sand, silt and sediment for dredging and desilting works. Mounted directly on standard excavator arms, it integrates a stirring agitator with the pumping system to loosen compacted sediment before suction, effectively avoiding clogging caused by settled dense sand layers. As an excavator sand dredging pump powered by the host excavator’s hydraulic circuit, it requires no extra independent power station and can start operation shortly after simple mounting.
Compared with large fixed dredging stations, a portable dredge pump mounted on an excavator moves freely across different work zones, adapting well to scattered dredging points and narrow water areas that heavy equipment cannot access. The full YG product lineup covers flow rates from 200 to 500 cubic meters per hour with corresponding lift capacities, matching varied dredging intensity demands.

Flow rate determines how fast the pump moves material. The YG series covers 150 to 500 m³/h. Higher flow rates move more material per hour but may require larger excavators to handle the weight and hydraulic flow.
Lift height determines how far the pump can push material vertically. The YG hydraulic dredging pump offers lifts from 10 to 40 meters. For applications where the discharge point is above water level—such as pumping to containment areas on riverbanks—higher lift is essential.
Agitator power determines how effectively the pump can break up settled sediment. Models with 5.5KW, 7.5KW, and 15KW agitators handle different material densities. The agitator loosens compacted sediment at the intake, preventing clogging and ensuring smooth material flow.
Features of Excavator Dredge Pump
An excavator dredge pump stands out from ordinary water pumps with targeted designs for abrasive sediment working conditions.
- Direct hydraulic drive system. The hydraulic dredging pump draws power directly from the excavator’s existing hydraulic system, eliminating the need for separate diesel or electric power units and greatly simplifying on-site deployment.
- Integrated submersible agitator. A built-in stirring agitator loosens compacted sand and silt layers before suction, keeping sediment in a suspended state and maintaining steady flow output during long continuous operation.
- High wear-resistant wetted components. All flow-contacting parts use abrasion-resistant materials to withstand scouring from sand particles, extending service life under long-term sediment transport conditions.
- Standard quick-mount interface. Universal pin connection design fits most mainstream excavator arm specifications, so on-site crews can attach or remove the unit quickly without custom structural modification.
- Flexible working depth adjustment. The portable dredge pump adapts to different underwater depths by adjusting the excavator arm position, suiting variable water level conditions across different project sites.
Nine Models for Different Operating Conditions
The YG series offers nine models, not because we wanted to fill a catalog, but because different jobs demand different pump configurations. One pump cannot do everything efficiently—either it moves too slowly for high-volume jobs, or it lacks the lift to reach high discharge points. The YG excavator dredge pump series covers flow rates from 150 to 500 m³/h and lift heights from 10 to 40 meters. This range means two different things: some projects require moving 500 cubic meters of material per hour, others require pushing material up to 40 meters high. These two requirements demand completely different pump configurations.
- Low-lift, high-flow models (YG400-10): 400 m³/h flow, only 10 meters lift. These models suit short-distance pumping—dredging from a riverbed to the riverbank, where the discharge point is close and elevation gain is minimal. The goal is maximum volume per hour, not maximum distance.
- High-lift, mid-flow models (YG250-35): 250 m³/h flow, 35 meters lift. These models suit applications where the discharge point is elevated—pumping up a riverbank, discharging into a settling pond on higher ground, or long-distance slurry transfer with elevation gain.
- Balanced models (YG300-20): 300 m³/h flow, 20 meters lift. These suit most standard applications, balancing between volume and distance. This is the “general duty” configuration that covers the majority of jobs.
The selection logic: Low lift means higher flow, high lift means lower flow. There is no single model that delivers both maximum flow and maximum lift—the two are fundamentally linked. The operator chooses the model that matches the actual site conditions: if the discharge point is close and low, go with high-flow. If the discharge point is far or elevated, go with higher lift. Knowing the discharge point location is the first step in selecting the right model.
6 FAQs About Excavator Dredge Pump
A: The YG series covers 10 to 40-ton excavators. The specific model depends on your excavator’s weight and hydraulic flow capacity.
A: Flow rate is the volume of material the pump moves per hour (m³/h). Lift height is the vertical distance the pump can push material. Higher flow moves more material. Higher lift reaches higher discharge points.
A: Yes. The YG series is designed for high-solids handling including sand, silt, gravel, and slurry. The agitator breaks up compacted material at the intake, and the pump moves it through the discharge hose.
A: Yes. The YG excavator dredge pump connects directly to the excavator’s auxiliary hydraulics. No external power source is required.
A: The pump uses the same quick coupler system as a standard bucket. Switching between the pump and bucket takes minutes.
A: The excavator sand dredging pump handles sand, silt, mud, gravel, slurry, and water-saturated materials. The agitator-equipped design allows handling of compacted sediment that standard pumps cannot manage.
