Hydraulic dredge pump is a hydraulic submersible slurry attachment mounted on excavator booms, designed to suck sand, sludge, tailings, and mixed solid-liquid materials without a standalone dredger investment.
Driven by the carrier’s original hydraulic system, the machine converts hydraulic power into suction force to complete dredging, sand mining, and tank cleaning works. Contractors in flood-prone Southeast cities rely on this unit to cut labor and vessel rental costs by over 60% during annual river renovation projects.

Complete Working Principle Of Hydraulic Dredge Pump
The core operation flow contains four continuous stages without manual auxiliary work. First, hydraulic agitators break compacted sediment into loose slurry. Second, rotating impellers of the excavator dredge pump attachment generate strong negative pressure to suck mixed mud into the pump chamber.
Third, slurry is pushed through discharge pipelines by centrifugal force. Finally, materials are delivered to designated stacking or dewatering zones. Operators finish full mounting and pipeline connection within 30 mins via standard quick pins for on-site rapid deployment.


7 Core Competitive Advantages Of Excavator Dredge Pump Attachment
- Low Overall Investment: Reuse existing excavator without purchasing dedicated dredging barges, cutting total project cost by up to 70%.
- Superior Site Flexibility: Compact structure accesses narrow waterways, small marinas, and fish ponds where large dredgers cannot reach.
- Bundle Procurement Discount: Package discounts for orders with breakers, augers, and mulchers. Contractors rely on hydraulic dredge pumps for all sediment removal tasks.
- Heavy Wear Resistance: Cr26 high-chrome wetted parts extend service life to 2000+ hours under regular sand dredging conditions.
- No Excavator Modification: Connect with breaker auxiliary hydraulic lines directly, zero disassembly on main boom or pump components.
- High Concentration Dredging: Built-in mixing cutters lift slurry concentration to 40%-50% and reduce repeated suction cycles.
- Wide Model Coverage: Full range from low-flow small units to high-lift heavy models matches 10–40 ton diggers for diversified projects.
Global Full-Scene Application Fields Of Hydraulic Dredge Pump
- River, lake, and reservoir flood control silt cleaning for ecological restoration.
- Port and dock maintenance dredging to guarantee safe navigation depth.
- River sand extraction and coastal land reclamation construction.
- Mine tailings pond, ball mill sediment tank waste slurry transportation.
- Municipal sewage plant ash and sludge pool regular clearance.
- Aquaculture fish and shrimp pond bottom silt removal for water quality improvement.
- Pipeline caisson construction bentonite slurry transfer and excavation overburden cleaning.
- Post-disaster emergency silt discharge and dyke reinforcement earth extraction.
Step-By-Step Model Matching Guide For Excavator Dredge Pump
- Excavator tonnage matching: 10–20T mini diggers choose YG200/YG150 series; 30–40T heavy carriers adopt YG300-30/YG400-40 high-lift units.
- Lift & flow judgment: YG500-15 high-flow for wide-area lake dredging; YG400-40 40m lift for long-distance pipeline delivery.
- Site limitation rules: Light units fit narrow waterways; heavy agitators suit mines. Buy an excavator dredge pump attachment for full sediment treatment jobs.
- Geological condition selection: Standard impeller for soft silt; thickened alloy cutter for coarse sand and mine tailings.
- Annual working cycle: Reinforced wear kits for year-round mining tasks; standard configuration for seasonal landscaping projects.
Frequently Asked Questions About Excavator Dredge Pump Attachment
A1: Nominal clean water flow ranges from 150–500m³/h; actual solid output equals 50%-60% of nominal flow at 40%-50% slurry concentration. YG500-15 can deliver 250–300 cubic meters of sediment hourly under normal river conditions.
A2: The YG400-40 model provides a maximum lift of 40 m, suitable for projects with long horizontal pipelines and vertical height differences.
A3: 30–80mm; fit screen for big stones. Contact sales for custom agitators & factory prices of hydraulic dredge pumps.
A4: YG200/YG150 fit 10–20T diggers; YG400/YG500 match 20–30T carriers; YG300-30/YG400-40 suit 30–40T heavy excavators. Matching depends on the excavator’s spare hydraulic flow and pressure parameters.
A5: 2000–3000 hours for ordinary river sand; 800–1500 hours for abrasive quartz tailings; up to 3000–5000 hours for pure fine silt. Operators inspect wear parts every 500 working hours.
A6: No extra modification needed; only connect existing breaker hydraulic pipelines with standard pin mounting brackets; disassembly is finished within half an hour.
