Hydraulic Excavator Pump Description
When your project demands moving high-density sand slurry in remote or deep-water locations, the Hydraulic Excavator Driven Submersible Sand Dredging Pump becomes your most reliable asset. The Hydroman® 200THY110-6P is exactly that: a 200mm 8 Inch Hydraulic Submersible Dredge Pump powered directly by an excavator’s hydraulic system. With 110kW Excavator Hydraulic Vertical Slurry Pump performance, it handles compacted, abrasive materials effortlessly. This Heavy Duty Sand Dredging Submersible Pump Hydraulic design eliminates electric cable limitations. As an Underwater Hydraulic Driven Dredging Pump for Sand, it operates at significant depths where standard pumps fail.
Unlike electric pumps that struggle with torque and depth restrictions, this unit converts your excavator’s hydraulic flow into brute pumping force. The vertical orientation allows direct mounting on the boom, turning your machine into a mobile dredging station. Whether you are mining river sand or maintaining industrial settling ponds, this pump delivers continuous, maintenance-friendly operation.
Design Features of the 200mm 8 Inch Hydraulic Submersible Dredge Pump
The Hydroman® 200THY110-6P is engineered for extreme abrasion and high solid concentrations. Below are five standout design features:
High-Chrome Wear Parts – The impeller, casing, and agitator are cast from high-chromium iron (hardness ≥58 HRC). This resists the grinding wear of sharp sand and gravel, extending service life 3–5 times longer than standard cast iron pumps.
Integrated Agitator/Cutter Head – Mounted below the suction inlet, the agitator fluidizes settled sand beds up to 70% solids by weight. It breaks crusted layers and creates a dense slurry before it enters the impeller, preventing cavitation and clogging.
Hydraulic Motor with Pressure-balanced Seal – A heavy-duty hydraulic motor (compatible with most excavator flows 200–400 L/min) is protected by a double mechanical seal plus an oil bath chamber. This allows continuous submerged operation at depths up to 60 meters without water ingress.
Compact Vertical Design – As a Vertical Submersible Pump for Excavator Dredging Work, the pump’s inline configuration reduces footprint. You can maneuver it into tight dredging pits, between pilings, or along revetments without removing the excavator bucket linkage.
Modular Cartridge Assembly – All wear components (agitator, suction cover, impeller) are replaceable as cartridges. A field crew can swap the wet end in under two hours, minimizing downtime. No special tools or factory alignment required.

River Sand and Gravel Mining in Remote Areas
Traditional electric dredge pumps need generators, long cables, and transformers—logistical nightmares in remote riverbeds. The Hydraulic Power 110kW 8 Inch Dredging Pump eliminates all that. Your excavator’s own hydraulic system becomes the power source. Mount the Hydroman® pump on the arm, lower it into the river channel, and start extracting sand at rates up to 800 m³/h (depending on slurry density).
The agitator loosens compacted gravel layers, while the high-chrome impeller shoots the mixture through 200mm discharge piping to your dewatering or screening plant. No external power, no cable tangles, and you can relocate the entire setup in minutes by simply driving the excavator to the next borrow pit.
Deep Harbor Maintenance and Silt Removal
Port authorities face constant sedimentation in approach channels and turning basins. Conventional submersible electric pumps are depth-limited (typically 30m due to cable and motor cooling issues). The Heavy Duty Sand Dredging Submersible Pump Hydraulic overcomes this because the hydraulic motor generates no heat that needs ambient water cooling; the return oil is cooled by the excavator’s radiator.
We have deployed the 200THY110-6P at effective depths of 55 meters, removing dense silt, clay, and fine sand from ship berths. The vertical orientation allows the pump to sit inside a protective cage or directly on the seabed, while the excavator stays on the dock or a floating pontoon. This combination cuts dredging costs by 40% compared to hiring a full-size trailing suction hopper dredger.
Frequently Asked Questions About the Heavy Duty Sand Dredging Submersible Pump Hydraulic
Q1: Can I run the Hydroman® 200THY110-6P on any medium-sized excavator?
Yes, but you need to match hydraulic flow and pressure. The pump requires 200–400 L/min at 250–350 bar. Most 20–35 ton excavators (e.g., Caterpillar 320–336, Komatsu PC200–PC350) meet this range. If your machine has lower flow, we offer flow dividers or a separate hydraulic power pack. Always check your excavator’s auxiliary hydraulic spec before ordering.
Q2: How does the agitator affect sand production rates?
The agitator is not a cutter; it’s a high-speed propeller that creates a vortex. For loose sand, it increases production by 30–50% because it prevents the pump from “sucking air” when the sand collapses. For compacted material (clay, hard-packed gravel), the agitator slowly erodes the bed. If you need to break rock or dense clay, ask about our optional carbide-tipped cutter head upgrade.
Q3: What maintenance schedule should I follow?
In abrasive sand (e.g., silica content >30%), inspect the high-chrome impeller every 200 operating hours. Replace when the vane edges round to less than 3mm thickness. The hydraulic motor requires only a quarterly oil sample check. The double mechanical seal typically lasts 1,500 hours in clean water, but in sandy slurry, we recommend replacing the seal cartridge every 800 hours to prevent motor damage.
Why Choose the Underwater Hydraulic Driven Dredging Pump for Sand Over Electric?
Most operators switch to hydraulic drive after one too many electric motor burnouts. Submerged electric motors rely on clean water for cooling—sand slurry clogs cooling jackets and melts windings. The Hydroman® pump’s hydraulic motor has no electrical components underwater. The only wear points are the wet end and the shaft seal. Additionally, hydraulic drive provides full torque even at zero RPM, meaning you can stall the agitator against a boulder without damaging the system. Electric motors would trip breakers or burn.
For projects requiring variable speed, the excavator’s flow control lever gives you infinite adjustment of pump output. No VFDs, no programming. Just muscle control.
