Hydroman® 150THY18.5-6P Pump Description
When sand and sediment clog waterways and mining ponds, equipment operators need a solution that is both powerful and practical. The Hydroman 150THY18.5 Hydraulic Suction Pump for Sand delivers exactly that—a robust, submersible attachment that turns any standard excavator into a high-performance dredging machine. With a 150mm discharge and an 18.5kW hydraulic power rating, this 6 Inch Hydraulic Submersible Pump for Excavator is engineered to handle the toughest slurry applications, from river desilting to mine tailings management. Whether you need a 150mm Discharge Hydraulic Dredging Pump for Sand or a reliable Excavator Hydraulic Driven Vertical Slurry Pump, this model is built to perform under extreme conditions. Below, we break down why the Hydroman® 150THY18.5-6P stands out in the world of underwater dredging equipment.
The Hydroman® 150THY18.5-6P is a vertical, centrifugal, submersible dredge pump designed specifically for excavator mounting. Unlike conventional electric pumps that require external power sources, this unit is powered entirely by the excavator's auxiliary hydraulic circuit. This Submersible Hydraulic Pump for Underwater Sand Removal attaches directly to the excavator's bucket linkage, allowing operators to navigate narrow, hard-to-reach areas without the need for specialized dredging vessels. The pump's integrated agitation impeller breaks up settled materials—such as sand, mud, and slag—creating a consistent slurry that flows easily through the discharge line. Built with high-chrome alloy wear-resistant components, this Heavy Duty Excavator Mounted Dredging Pump is designed to withstand the most abrasive conditions while delivering continuous, reliable performance.
Design Features of the Hydroman® 150THY18.5-6P
What makes this excavator-mounted pump truly exceptional? The engineering team at Hydroman® has incorporated several key design features that set the 150THY18.5-6P apart from conventional dredging equipment:
Heavy-Duty High-Chrome Construction: All wetted parts—including the pump casing, impeller, guard plate, and mixing impeller—are manufactured from high-chrome alloy, providing exceptional resistance to abrasion and extending service life even when pumping sand, gravel, and mining tailings.
Bottom-Mounted Agitation Impeller: In addition to the main pumping impeller, the pump features a dedicated bottom agitation impeller that sprays deposited solids into turbulent flow. This design enables high-concentration conveying without auxiliary devices, significantly reducing clogging and improving pumping efficiency.
Hydraulic Drive with Variable Speed Control: Powered directly by the excavator's hydraulic system, the pump offers stepless speed regulation. Operators can adjust flow rates on the fly to match changing slurry conditions, and the hydraulic system provides automatic overload protection—eliminating the risk of motor burnout common with electric pumps.
Advanced Double Mechanical Seal: The unique sealing device effectively balances pressure inside and outside the oil chamber, protecting the mechanical seal and ensuring reliable long-term operation even at significant submersion depths.
Quick-Attach Mounting System: The pump connects to the excavator's bucket linkage using standard auxiliary hydraulics, allowing for rapid installation and removal. Operators can switch between digging and dredging in minutes without costly modifications to their equipment.

Submersible Hydraulic Pump for Underwater Sand Removal
One of the most demanding applications for any dredging pump is underwater sand extraction. Rivers, lakes, and harbors accumulate sediment over time, reducing navigable depth and threatening marine infrastructure. Traditional methods—such as mechanical dredging or electric submersible pumps—often fall short due to limited mobility, high setup costs, or electrical safety concerns in wet environments.
The Hydroman® 150THY18.5-6P excels in precisely these scenarios. As a Submersible Hydraulic Pump for Underwater Sand Removal, it operates fully submerged while leveraging the excavator's hydraulic arm to access any location the machine can reach. The bottom agitator breaks up compacted sand beds, and the 150mm discharge moves high volumes of sand-water mixture efficiently. Because the pump uses hydraulic rather than electric power, there is zero risk of electrical shock underwater—a critical safety advantage for marine and offshore operations.
Typical underwater sand removal projects where this pump proves invaluable include:
Harbor and marina desilting to restore depth for vessel navigation
River channel maintenance to prevent flooding and improve water flow
Dam and reservoir sediment cleanup to recover storage capacity
Beach reclamation and coastal protection projects requiring sand relocation
Underwater construction site preparation and caisson emptying
Heavy Duty Excavator Mounted Dredging Pump for Mining & Industrial Waste
Beyond sand removal, the Hydroman® 150THY18.5-6P is purpose-built for the harsh realities of mining and industrial waste management. Tailings ponds, settling tanks, slag pits, and crusher sumps all require regular cleaning to maintain operational efficiency and environmental compliance. However, the materials found in these settings—coal tailings, mill scale, blast furnace slag, and abrasive ore slurries—quickly destroy standard pumps.
As a Heavy Duty Excavator Mounted Dredging Pump, the 150THY18.5-6P is engineered to handle solids concentrations up to 70% by weight and specific gravity as high as 1.7. The high-chrome alloy construction resists the extreme abrasion caused by sharp particles and dense slurries, while the hydraulic drive provides the torque needed to move thick, viscous mixtures that would stall electric pumps. The excavator mounting means the pump can be positioned precisely where needed—whether deep in a tailings pond or inside a confined sump pit—without requiring separate support equipment.
Key mining and industrial applications include:
Tailings pond reclamation and slurry transfer
Coal mine sump cleaning and slurry handling
Mill scale and slag pit dewatering
Underground slimes collection and conveyor tunnel sumps
Industrial wastewater treatment and sludge removal
Barge and tank cleaning operations
Frequently Asked Questions (FAQ)
Q1: What size excavator is compatible with the Hydroman 150THY18.5 Hydraulic Suction Pump for Sand?
The Hydroman® 150THY18.5-6P is designed to work with small to medium-sized excavators, typically in the 15 to 25 ton range. The pump's hydraulic motor requires an auxiliary hydraulic flow rate that matches the excavator's output capacity. For specific compatibility information based on your excavator model and hydraulic specifications, direct consultation with Hydroman®'s technical team is recommended to ensure optimal performance.
Q2: How deep can the 6 Inch Hydraulic Submersible Pump for Excavator operate underwater?
The Hydroman® 150THY18.5-6P is capable of operating at submersion depths up to approximately 80 meters (260 feet), depending on the specific configuration and hydraulic hose length. The double mechanical seal system is specifically engineered to maintain integrity at depth, preventing water ingress and protecting internal components. For applications requiring greater depth, Hydroman® offers specialized configurations and should be contacted directly for engineering consultation.
Q3: What maintenance does the 150mm Discharge Hydraulic Dredging Pump for Sand require?
Regular maintenance for this pump primarily involves inspecting the high-chrome wear parts—including the impeller, casing liner, and agitator—for signs of abrasion. Because the pump uses hydraulic rather than electric drive, there are no electric motors to burn out or complex electrical components to fail. The mechanical seal should be checked periodically, and hydraulic hoses should be inspected for leaks or damage. Many operators find that the low-maintenance design significantly reduces downtime compared to traditional electric submersible pumps.
