Hydroman 80THY55-6P Pump Description
When conventional excavator buckets fail to remove waterlogged sediment, the Hydroman 80THY55-6P Hydraulic Dredging Pump for Excavators provides the solution. This 80THY55-6P Excavator Mounted Hydraulic Sand Pump transforms any standard excavator into a high-performance dredging machine. The Hydroman 3 Inch Hydraulic Submersible Sand Dredge Pump is engineered for vertical submersion, tackling sand and slurry where other equipment cannot operate. Powered by the machine's own hydraulics, this 55kW Excavator Hydraulic Driven Submersible Pump delivers exceptional solids-handling capability in challenging underwater conditions.
The Hydroman 80THY55-6P Hydraulic Dredging Pump for Excavators is not just another attachment—it is a purpose-built tool that replaces the bucket entirely. Designed for vertical submersion, this pump operates fully underwater, extracting sand, slurry, and sediment directly from the bottom of ponds, rivers, and harbors.
The system draws power directly from the excavator's auxiliary hydraulic lines. No external generators, no long electrical cables, and no complex setup. The result is a highly mobile dredging solution that goes wherever the excavator can reach.
How does the 80THY55-6P differ from standard submersible pumps?
Standard electric submersible pumps require dedicated power sources and often cannot handle high solids concentrations. The 80THY55-6P Excavator Mounted Hydraulic Sand Pump runs on hydraulic power, which eliminates electrical hazards in underwater applications and delivers higher torque for pumping thick, abrasive materials. Its vertical design allows direct immersion, making it far more effective for sediment removal than any bucket attachment.
Design Features of the Hydroman 3 Inch Hydraulic Submersible Sand Dredge Pump
The engineering behind the Hydroman 3 Inch Hydraulic Submersible Sand Dredge Pump focuses on durability, efficiency, and ease of operation in demanding environments.
High-Chrome Wear-Resistant Construction – All critical flow components—including the pump casing, impeller, guard plate, and stirring impeller—are cast from high-chromium wear-resistant alloy (Cr26). This material undergoes specialized heat treatment to withstand prolonged exposure to abrasive sand and slurry particles.
Hydraulic Direct Drive Integration – The pump connects directly to the excavator's existing auxiliary hydraulic system, eliminating the need for separate power sources. This plug-and-play design is ideal for remote job sites where electricity is unavailable or impractical.
Bottom Agitation Impeller – A built-in stirring device prevents sediment from settling at the pump inlet. The agitator continuously lifts settled solids into suspension, ensuring a consistent flow of high-density slurry into the pump chamber.
Double Mechanical Seal Protection – The sealing system features dual mechanical seals with pressure compensation, effectively balancing internal and external pressures to prevent water ingress and protect the hydraulic motor during extended submerged operation.
Vertical Submersible Configuration – Designed for vertical deployment, the pump sits directly on the sediment surface when lowered by the excavator boom. This orientation maximizes suction efficiency and allows the pump to reach deep deposits that horizontal pumps cannot access.

Harbor and Port Maintenance with the 55kW Excavator Hydraulic Driven Submersible Pump
Siltation is a persistent problem for harbors, marinas, and dock loading facilities. Accumulated sediment reduces water depth, restricts vessel access, and increases maintenance costs. Traditional dredging requires dedicated cutter suction dredgers or clamshell buckets—both slow and expensive.
The 55kW Excavator Hydraulic Driven Submersible Pump offers a faster, more cost-effective alternative. By mounting this pump directly onto an excavator already present at the port, operators can begin dredging within minutes. The pump extracts silt and sand from berths, turning basins, and approach channels, discharging the slurry through pipelines to designated disposal areas hundreds of meters away.
Unlike mechanical buckets that stir up sediment without removing it efficiently, the Vertical Hydraulic Submersible Pump for Sand Dredging continuously extracts material, achieving high solids concentrations that minimize water handling and reduce disposal volumes.
Underwater Sand Extraction with the Underwater Excavator Hydraulic Sand Removal Pump System
Commercial sand extraction from riverbeds and lake bottoms presents unique challenges. Water depth, current flow, and the need to avoid environmental disruption all complicate operations. Conventional excavator buckets cannot operate effectively underwater, and mechanical dredgers are often too large or expensive for smaller extraction sites.
The Underwater Excavator Hydraulic Sand Removal Pump System solves these problems. The excavator positions the pump directly over the sand deposit, lowers it vertically into the water, and begins pumping. The agitation impeller breaks up compacted sand beds, creating a turbulent slurry that flows easily through the pump and into the discharge pipeline.
This system is particularly effective for recovering sand from depths where a standard bucket cannot reach. The excavator's reach allows the pump to access deposits up to several meters below the water surface, all while the operator remains safely on dry land or a stable platform.
Frequently Asked Questions About the Hydroman 80THY55-6P Slurry Sand Dredging Pump
Q1: What solids concentration can the Hydroman 80THY55-6P Slurry Sand Dredging Pump handle?
The Hydroman 80THY55-6P Slurry Sand Dredging Pump is engineered to handle solids concentrations of 30–40% by volume, with peak capabilities reaching up to 70% by weight depending on material type and operating conditions. This high concentration ratio significantly reduces the volume of water transported, lowering disposal costs and increasing operational efficiency.
Q2: What excavator size is required to operate this pump?
The 80THY55-6P Excavator Mounted Hydraulic Sand Pump is designed for excavators in the 15- to 25-ton range. The pump requires hydraulic oil flow of approximately 180–250 L/min at operating pressures of 20–32 MPa. Most mid-sized excavators from major manufacturers (Caterpillar, Komatsu, Hitachi, Kobelco, Volvo) can power this pump using their existing auxiliary hydraulic circuits.
Q3: How does the vertical design improve dredging performance?
The Vertical Hydraulic Submersible Pump for Sand Dredging positions the pump inlet directly against the sediment surface. This orientation maximizes suction efficiency because the pump does not need to lift material laterally before moving it vertically. The vertical configuration also allows the excavator boom to precisely position the pump over targeted deposits, making it ideal for selective dredging in confined areas such as marinas, intake towers, and caissons.
