The excavator mounted dredge pump is a professional hydraulic dredging accessory designed to mount directly on excavator booms. Unlike traditional electric dredging pumps and large dredging vessels, this equipment uses the excavator’s original hydraulic system as its core power source. It requires no external generator, no power cables, and no fixed installation. It is specially developed for complex on-site environments such as river silt accumulation, reservoir desilting, port channel cleaning and shallow sea sand pumping. Equipped with underwater stirring impellers and high-chromium wear-resistant pump body, the excavator dredge pump can stir, suck, and transport high-concentration mud, sediment, and fine gravel underwater continuously.
Many project owners and contractors focus on reasonable excavator dredge pump price and stable long-term performance. Compared with traditional dredging methods, excavator-mounted dredge pumps feature stronger flexibility, lower failure rate and wider scene adaptability, becoming the mainstream mobile dredging equipment for global water conservancy and municipal projects.

Case 1: Malaysia Urban River Desilting Project
Customer Background
The client is a local Malaysian environmental engineering contractor, mainly responsible for urban inland river dredging and water ecological improvement. The company only owns 18-ton small excavators, and undertakes long-term small and medium-sized river desilting projects. After comparing excavator dredge pump price and performance parameters, they chose our YG200-15 excavator dredge pump attachment.
Main Construction Difficulties
- Narrow Water Channel Restriction: Urban Malaysian rivers are narrow, with dense urban facilities on both sides. Large dredging vessels and high-flow pumps cannot operate normally, resulting in low daily dredging volume.
- Low Adaptation of Ordinary Pumps: Common dredge pumps do not match 18-ton excavators, resulting in insufficient power, frequent stalling, and unstable pumping.
- Shallow Water & Low-Lift Working Demand: The local river sediment layer is thin, requiring low-lift and stable-flow pumping. High-lift pumps waste power and cause construction redundancy.
Customized Solution
We recommended the YG200-15 excavator-mounted dredge pumps, perfectly matching the client’s 18-ton excavator. This model features 200m³/h flow, 15m lift, a 5.5KW matched agitator and 1556 stirrer torque. It provides stable stirring and suction power, fully adapting to shallow water, narrow rivers, and low-lift desilting working conditions.
Effects
- Perfect Equipment Matching: The pump fits 18ton excavators perfectly, with no hydraulic overload or power shortage, achieving continuous and stable operation.
- Improved Dredging Efficiency: The 200m³/h stable flow greatly improves daily sediment removal capacity, finishing river renovation tasks ahead of the project deadline.
- Zero Environmental Disturbance: Hydraulic silent operation meets Malaysia’s urban environmental protection standards, with no noise complaints or construction shutdowns.
Customer Feedback
“The YG200-15 excavator dredge pump is tailor-made for our small excavator and urban river projects. The stirrer torque is stable and never blocks with river silt. The reasonable excavator dredge pump price and reliable performance help us save lots of construction costs. It is the best small-scale dredging attachment for urban environmental projects.”
Case 2: Brazil Coastal Beach Reclamation Project
Customer Background
The Brazilian customer is a large local water conservancy construction company, focusing on coastal beach renovation, land reclamation, and port sediment cleaning. The company is equipped with 28-ton excavators and needs high-flow, high-lift dredging equipment for large-scale batch operations. They purchased our YG400-30 excavator dredge pump attachment.
Main Construction Difficulties
- Large Dredging Volume Demand: Beach reclamation requires massive sand and sediment transportation. Low-flow pumps cannot meet the tight project schedule.
- Complex Coastal Sediment Composition: Coastal sediment contains fine sand and small gravel, which can easily cause ordinary pump blockage and wear.
- Medium-Lift Long-Distance Transportation Requirement: The project needs 30m lift capacity to realize long-distance sediment discharge, limiting the use of low-lift dredge equipment.
Customized Solution
We adopted YG400-30 heavy-duty excavator-mounted dredge pumps, suitable for 28ton excavators. With 400m³/h ultra-large flow, 30m stable lift and high-strength stirring system, this model delivers super strong suction and anti-blocking ability, fully meeting high-intensity coastal reclamation construction demands.
Actual Working Effects
- Massive Efficiency Improvement: 400m³/h high flow realizes large-volume continuous sand pumping, greatly shortening the whole reclamation project cycle.
- Stable Anti-Blocking Performance: The optimized stirring structure handles mixed sand and gravel smoothly, eliminating frequent blockage and shutdown problems.
- Qualified Long-Distance Discharge: 30m standard lift supports long-distance sediment transportation, fully meeting the technical requirements of Brazilian coastal engineering.
Customer Feedback
“The YG400-30 excavator dredge pump has powerful flow and stable lift performance. It works non-stop in our harsh coastal environment with zero failures. The high-performance excavator mounted dredge pump greatly improves our project profit, and we will order more units for subsequent coastal projects.”
7 Buying Advice for Excavator Dredge Pump
1. Match Pump Model to Excavator Tonnage
Medium standard dredge pumps fit 10–30 ton excavators for small river and pond desilting. Heavy-duty versions match 30–40 ton machines for coastal sand extraction and land reclamation. Improper matching triggers insufficient power or hydraulic overload, damaging both pump and excavator.
2. Check Hydraulic Parameter Compatibility
Verify the excavator’s hydraulic flow and working pressure against the pump motor’s rated requirements. Mismatched flow or pressure shortens the pump’s service life; insufficient parameters fail to reach rated flow and lift, while excessive pressure burns out hydraulic components. Also confirm the pump’s heat dissipation design for long-hour continuous operation without overheating.
3. Prioritize Anti-Blocking & Wear-Resistant Structure
Select pumps fitted with bottom stirring impellers and high-chromium alloy flow parts including impellers, pump casings and wear liners. High-chromium materials resist abrasion from gravel, seawater and mixed garbage sediment. Narrow flow channels easily jam large impurities, so confirm the internal passage size matches the maximum stone size on site.
4. Calculate Actual Lift & Conveying Distance
Estimate vertical lift and horizontal pipeline length before purchase. Pipeline friction loss reduces effective delivery power. The pump’s rated lift must exceed actual working demand; insufficient lift leads to weak mud output or complete flow interruption for long-distance transportation.
5. Evaluate Price Based on Long-Term Cost Performance
Never only choose the lowest excavator dredge pump price. Cheap pumps use thin cast iron parts and unstable hydraulic systems, causing frequent breakdowns. Premium alloy pumps have fewer maintenance fees and longer service life, delivering better overall long-term investment returns.
6. Confirm Installation Interface & Drive Type
Check quick connector specifications, hydraulic pipe diameter and port type to match the excavator’s pipeline for stable assembly. Hydraulic-driven dredge pumps offer maximum mobility, while large projects may need separate diesel or electric pump units as alternative options.
7. Confirm After-Sales Support & Spare Parts Supply
Cooperate with official manufacturers that provide on-site installation guidance, operator training and full stock of replacement parts. Reliable spare parts supply avoids unexpected construction shutdowns caused by damaged wearing components during heavy-duty dredging work.
