4 Side Cutters Pump Description
When your project demands reliable solids handling in remote locations, the Hydroman® 200THY45-6P Hydraulic Driven Dredging Pump delivers unmatched durability and efficiency. This 200THY45-6P Submersible Hydraulic Pump for Dredging features an 8-inch discharge port engineered for high-volume slurry transport. As a true 8 Inch Hydraulic Slurry Pump for Underwater Operations, it excels where electric power is unavailable, leveraging excavator hydraulics to move heavy sediment. This 45kW Hydraulic Submersible Pump for Heavy Sediment operates as a Vertical Hydraulic Pump for Deepwater Dredging Tasks, making it the ultimate High Capacity Hydraulic Pump for Sand Excavation.
The Hydroman® 200THY45-6P Hydraulic Driven Dredging Pump is engineered as a centrifugal, hydraulically driven submersible pump specifically designed for handling abrasive slurries, silt, and sand in challenging underwater environments. Unlike electric pumps that require generators and power cables, this unit connects directly to the hydraulic system of an excavator, crane, or dedicated hydraulic power pack, offering unparalleled mobility and operational flexibility. Its rugged construction and high-chrome alloy wear parts make it a trusted workhorse for contractors worldwide.
Key Design Features of the 200THY45-6P Submersible Hydraulic Pump for Dredging
High-Chrome Abrasion Resistance: All wear components—including the casing, impeller, and agitator—are constructed from 27% high-chrome alloy with HRC65 hardness, providing exceptional resistance to sand, gravel, and abrasive slurries. This significantly extends service life and reduces downtime for parts replacement.
Integrated Agitator System: The pump is equipped with a high-efficiency agitator impeller mounted on the shaft. This agitator stirs settled solids directly into a fluid slurry mixture before suction, enabling solid concentrations of up to 70% by weight. For compacted materials, optional hydraulic side cutters can be added to further break up hard sediment beds.
Robust Hydraulic Motor Drive: Powered by a high-torque hydraulic motor, the pump operates at low rotation speeds, reducing wear on internal components. It connects seamlessly to excavator auxiliary hydraulics or standalone hydraulic power units, eliminating the need for electrical infrastructure on site.
Vertical Submersible Configuration: Designed for vertical operation while fully submerged, the pump can be deployed via excavator arm or crane cable at working depths up to 250 meters. Its compact vertical profile allows operation in confined spaces such as narrow canals, cofferdams, and dredge ponds.
Double Mechanical Seal Protection: A dual mechanical sealing arrangement prevents water ingress and slurry contamination of the hydraulic motor, ensuring reliable performance even during extended submerged operation.
Large Solids Passage: The pump handles maximum solid particles up to 60mm in diameter, allowing it to pass gravel, rocks, and debris without clogging—critical for mining tailings and river dredging applications.

Mining & Quarrying – Sand Production and Tailings Management
In mining and quarrying operations, the High Capacity Hydraulic Pump for Sand Excavation is indispensable for extracting sand, gravel, and minerals from flooded pits and settling ponds. Traditional electric pumps are vulnerable to moisture, require expensive waterproofing, and demand long power cable runs—none of which are practical in remote mining sites.
By mounting the Hydroman 200THY45-6P directly onto an excavator, operators gain a mobile, self-contained dredging system that can move from one extraction zone to another in minutes. The pump efficiently handles mine tailings, slurry ponds, and sediment-laden water, achieving solid concentrations that maximize transport efficiency. Its high-chrome wear parts withstand the punishing abrasion of silica sand and crushed rock, delivering thousands of hours of service between overhauls.
River and Canal Dredging – Navigation Restoration and Flood Control
Maintaining navigable waterways and preventing flooding requires continuous sediment removal from rivers, canals, and reservoirs. The Vertical Hydraulic Pump for Deepwater Dredging Tasks excels in these environments because it can be operated from an excavator positioned on the bank or from a small pontoon. The vertical submersible design allows the pump to reach deep channels where silt and sand accumulate, while the agitator loosens compacted deposits before suction.
Hydraulic drive eliminates the electrocution risks associated with electric submersible pumps in wet conditions, making it safer for crews working in and around water. Whether restoring shoreline capacity, removing contaminants, or deepening navigation channels, this pump delivers reliable, high-volume slurry transport without the logistical burden of generators and power distribution equipment.
Frequently Asked Questions About the Hydroman 200THY45-6P Hydraulic Pump
Q: What hydraulic power source is required to operate the 45kW Hydraulic Submersible Pump for Heavy Sediment?
A: The pump requires a hydraulic power source delivering oil flow rates appropriate for its motor displacement. It is designed to connect directly to the auxiliary hydraulic circuit of medium to large excavators (typically 20-ton class and above) or to standalone diesel-driven hydraulic power packs. The hydraulic motor operates at pressures up to 350 bar, ensuring consistent torque even under heavy solids loading.
Q: How does the agitator system improve dredging performance?
A: The agitator impeller rotates at the same speed as the main pump impeller, creating a vortex that lifts settled solids from the bottom and mixes them into a pumpable slurry. Without an agitator, pumps must rely on suction alone, which is ineffective against compacted sediment. The agitator achieves solid concentrations of up to 70% by weight, meaning more solids and less water are pumped per cubic meter—dramatically improving production rates and reducing energy costs.
Q: Can the pump be customized for specific abrasive conditions or aggressive chemicals?
A: Yes. While the standard configuration uses 27% high-chrome alloy for general abrasive slurry handling, Hydroman offers material upgrades including Hyperchrome (for extreme abrasion), SS304/SS316L stainless steel (for corrosive environments), CD4MCu (for combined abrasion and corrosion), and Duplex 2205 (for marine and chloride-rich applications). This flexibility allows the pump to be tailored to mining tailings, chemical plant effluents, or saltwater dredging projects.
