The construction and mining industries demand equipment that operates reliably under extreme conditions. The Hydroman® 80THY11 distinguishes itself from standard centrifugal pumps by utilizing the excavator’s own hydraulic system. This eliminates the need for external power sources or complex electrical setups near water. It is a true Heavy Duty Hydraulic Pump for Slurry Applications, built to withstand the abrasive nature of sand, gravel, and industrial sludge.
Unlike traditional diesel-powered pumps that require separate fuel and maintenance schedules, this unit integrates seamlessly with your existing heavy machinery. The hydraulic drive offers infinite speed control, allowing operators to match the pump speed precisely to the slurry density, optimizing fuel consumption and reducing wear.
Design Features of the Hydraulic Submersible Pump for Underwater Sand Removal
The Hydroman® 80THY11 is built with a focus on durability, serviceability, and pure hydraulic power. Below are the six key design features that make this the preferred Underwater Vertical Dredging Pump for Excavator Use.
The unit utilizes a high-torque hydraulic motor with an 11kW power rating. This direct drive system eliminates the mechanical losses associated with gearboxes or belt drives, ensuring that 100% of the hydraulic energy is transferred directly to the impeller. This results in instant torque for breaking up compacted materials.
Clogging is the number one enemy of dredging efficiency. The Hydraulic Submersible Pump for Underwater Sand Removal features a large-passage open impeller. This design allows the pump to handle spherical solids up to 3 inches (76mm) in diameter, passing debris that would typically stall a conventional pump.
To combat the wear caused by silica sand and sharp aggregates, the pump casing and impeller are manufactured from high-chrome alloy (Ni-Hard). This metallurgy extends the operational lifespan significantly compared to standard cast iron pumps when dealing with abrasive slurries.
The 80THY Vertical Submersible Pump for Dredging is equipped with a high-pressure agitator located at the suction inlet. This agitator fluidizes settled solids, creating a high-concentration slurry directly at the pump intake. This feature eliminates the need for a separate water cannon to mobilize the material.
Engineered for total submersion, the unit features a robust, sealed housing that protects the hydraulic motor from water ingress. It can operate in depths exceeding standard excavator reach limits, ensuring reliability in flooded pits, deep marinas, and underwater foundation projects.
The pump attaches to the excavator arm via a universal skid mount. This allows for 360-degree articulation, enabling the operator to dredge at difficult angles, clean out sloping banks, and reach into confined spaces that are inaccessible to floating dredges.

While the 80THY11 is versatile across many industries, two specific sectors benefit immensely from its unique capabilities. Unlike traditional dredging methods that require extensive setup time, this excavator-driven unit offers mobility and precision.
Mining Tailings and Sludge Remediation
In the mining industry, managing tailings ponds and settling basins is a critical environmental and operational challenge. The Excavator Driven Dredge Pump 11kW Power is the ideal tool for this environment. Operators can position the excavator at the edge of the tailings dam and use the long reach of the boom to access the settling ponds. The hydraulic agitator breaks down the settled solids, while the pump transfers the material to a dewatering system or disposal area.
Why it excels here: Unlike electric submersible pumps that pose a spark risk or require GFCI protection in wet environments, the hydraulic drive system is intrinsically safe for use around flammable or volatile tailings. Furthermore, the ability to move the pump head without moving the excavator tracks minimizes ground disturbance and environmental impact.
Port Maintenance and Marina Desilting
Marinas and ports require constant maintenance to prevent silt accumulation that can impede vessel navigation. The 3 Inch Excavator Mounted Hydraulic Slurry Pump offers a highly mobile solution for these tight quarters. Instead of mobilizing a large cutter suction dredge (CSD) which is costly and requires transport permits, a standard excavator fitted with this pump can be driven directly onto the dock or barge.
Why it excels here: The precision of the excavator arm allows for targeted dredging around pilings and dock supports without causing structural damage. The pump efficiently handles the sandy and silty sediment typical of harbors, pumping it through a discharge hose to a disposal site or reclamation area up to several hundred meters away.
Frequently Asked Questions (FAQ)
Q1: What are the hydraulic flow requirements for the 80THY11 Hydraulic Dredging Pump for Excavator?
A: The 80THY11 Hydraulic Dredging Pump for Excavator is optimized for excavators in the 8 to 15-ton class. It requires a hydraulic flow rate between 60 to 110 liters per minute (L/min) and operates at a maximum pressure of 250 bar. It is designed with a direct-mount interface, utilizing the excavator’s auxiliary hydraulic circuit without the need for complex modifications.
Q2: How does the Hydraulic Submersible Pump for Underwater Sand Removal handle high solid content without clogging?
A: Unlike standard centrifugal pumps that rely on suction alone, this unit functions as an Underwater Vertical Dredging Pump for Excavator Use that utilizes a mechanical agitator. The agitator creates a vortex directly in front of the suction inlet, mixing sand and water into a homogeneous slurry. The open impeller design then allows this slurry—containing large particles—to pass freely through the 3-inch discharge outlet without clogging.
Q3: Can the Heavy Duty Hydraulic Pump for Slurry Applications run dry without damage?
A: While the Heavy Duty Hydraulic Pump for Slurry Applications is designed for submerged use, the hydraulic drive motor is capable of running dry for short periods without the risk of electrical burnout. However, to protect the mechanical seal and internal wear components, continuous dry running is not recommended. The hydraulic system provides overload protection, automatically bypassing pressure if the pump encounters a blockage or runs dry, preventing damage to the excavator or pump.
Maximize Your ROI with Hydroman® Technology
Investing in the Hydroman® 80THY11 is a strategic decision for contractors looking to expand their service offerings. By converting your existing excavator into a high-production dredge, you eliminate the capital expenditure of purchasing a dedicated dredge vessel. The unit’s modular design allows for rapid attachment and detachment, meaning your excavator can return to standard digging duties within minutes of completing a dredging cycle.
Furthermore, the operational cost savings are substantial. The hydraulic efficiency reduces fuel consumption per cubic meter of material moved compared to conventional dredging methods. The robust construction ensures that maintenance intervals are extended, keeping your project on schedule and under budget.
Don’t let sediment, sludge, or sand slow down your next project. The Hydroman® 80THY11 Hydraulic Dredging Pump for Excavator is ready to provide the reliability and power you need.
