150THY Excavator Pump Description
When heavy slurry needs to be removed from underwater sites, the Hydroman 150THY Excavator Mounted Hydraulic Dredge Pump stands out. This 150THY45-6P Hydraulic Pump for Excavator Dredging functions as a 6 Inch Excavator Hydraulic Submersible Slurry Pump, capable of moving sand, silt, and debris with ease. As a Vertical Excavator Pump for Underwater Dredging Work, it operates while fully submerged, agitating settled materials into a pumpable slurry. The 45kW Hydraulic Dredged Pump for Heavy Slurry delivers exceptional cutting power and flow rates, making it a go-to choice for contractors who need to convert a standard excavator into a high-performance dredger. Unlike electric submersible pumps, this unit draws power directly from the excavator’s auxiliary hydraulic circuit, eliminating the need for external generators or long power cables. Whether you are cleaning out an industrial lagoon or reclaiming sand from a riverbed, this attachment brings portability, durability, and high solids handling capacity to the job site. Below we break down its design, real-world applications, and answers to common questions.
Key Design Features of the 150THY45-6P Hydraulic Pump for Excavator Dredging
The 150THY45-6P Hydraulic Pump for Excavator Dredging is engineered for continuous, abrasive-heavy work. Here are four standout design features that separate it from conventional dredging attachments:
Hydraulic-Driven Agitation System – A built-in auger or optional side cutters churn up compacted sand, gravel, and sludge right at the pump inlet. This creates a high-concentration slurry (up to 70% solids by weight) without needing a separate jetting ring or water injection. Operators report that even after years of sediment compaction, the agitator breaks material loose in seconds.
Wear-Resistant Wet End Components – The pump casing, impeller, and wear plates are cast from high-chrome alloy (hardness >58 HRC). This material withstands the continuous abrasion from sharp sand particles, small stones, and mining tailings. In field tests, the service life of the wet end is 3–5 times longer than standard cast iron pumps when handling silica sand.
Direct Mounting to Excavator Boom – A reinforced steel mounting bracket attaches to the boom arm’s pin locations, allowing the pump to be positioned precisely at any depth or angle. The hydraulic hoses connect to the excavator’s auxiliary circuit via quick couplers, so changeover from bucket to pump takes less than 15 minutes. No extra crane or floating platform is required.
Dry-Running Protection and Cooling – A mechanical seal with an oil bath chamber prevents ingress of water and fines, while the hydraulic motor casing acts as a heat sink. Even when the pump briefly runs above water (e.g., during repositioning), the design tolerates intermittent dry operation without seal failure—a common weak point in cheaper submersible pumps.
These features make the Excavator Mounted Pump for Sand and Mud Removal a reliable tool for operators who face unpredictable underwater conditions, from loose silt to compacted clay.

Mining & Tailings Dam Rehabilitation
In active mining sites, tailings ponds accumulate fine solids that must be removed periodically to maintain storage capacity. The 6 Inch Excavator Hydraulic Submersible Slurry Pump is lowered directly into the tailings dam from the edge, eliminating the need to drain the pond or build a floating dredge. Its vertical orientation allows it to pump slurry with up to 40% solids content (by volume) to a disposal area hundreds of meters away.
One copper mine in Chile reported reducing their tailings cleanout time by 60% after switching from a ladder-mounted electric pump to this hydraulic excavator attachment. The pump handles not only copper tailings but also coal slurry, red mud from bauxite processing, and phosphate slimes. Because the excavator’s cab is positioned above water, the operator has full visibility of the pump’s intake, avoiding buried obstacles like geotextile fabric or old pipes.
Port and Harbor Desilting Without Dry Docking
Navigational channels and berthing pockets accumulate dense silt and sand over time, reducing draft depth. Traditional dredging requires large cutter suction dredgers or dry-docking the port area—both expensive and slow. With the Vertical Excavator Pump for Underwater Dredging Work, a long-reach excavator positioned on the quayside or a barge can access hard-to-reach corners under piers and between mooring dolphins.
The pump’s 6-inch discharge line moves material through floating HDPE pipes to a dewatering site onshore. A harbor master in Rotterdam shared that using this pump for spot dredging around lock gates reduced vessel waiting times by 30%, as they could clear shoaling in a single tide cycle without closing the channel. The Submersible Hydraulic Pump for Excavator Applications also works well for cleaning out dry docks after ship repairs, where thick mixtures of sandblasting grit, rust flakes, and oil residue need to be removed.
Frequently Asked Questions About the 45kW Hydraulic Dredged Pump for Heavy Slurry
Q1: What excavator size is compatible with the 45kW Hydraulic Dredged Pump for Heavy Slurry?
A: The pump requires an excavator with auxiliary hydraulic flow between 200 and 320 L/min (53–85 GPM) at operating pressures of 250–350 bar. Typical carriers are 20–35 metric ton class excavators (e.g., Caterpillar 320–336, Komatsu PC200–PC350, Hitachi ZX210–ZX330). Smaller machines may not provide enough flow to reach the pump’s full 45kW output, while larger units may need a flow regulator to avoid overspeeding the hydraulic motor. Always check your machine’s hydraulic spec sheet against the pump’s requirements before ordering.
Q2: Can the 6 Inch Excavator Hydraulic Submersible Slurry Pump run out of water for short periods?
A: Yes, but with caution. The pump’s mechanical seal is lubricated by an oil bath, so it can tolerate brief dry runs (30–60 seconds) while repositioning or when the water level drops unexpectedly. However, extended dry operation above 2 minutes will overheat the hydraulic motor and damage the seal. Many operators install a low-water cutoff sensor or rely on the excavator’s camera to monitor the pump inlet. For applications where water levels fluctuate rapidly, consider adding a float switch to the hydraulic control circuit.
Q3: How do you maintain the Vertical Excavator Pump for Underwater Dredging Work after pumping abrasive slurry?
A: After each shift, flush the pump with clean water by lowering it into a freshwater tank or using a separate water hose while the pump runs at low speed. This removes sand particles from the seal faces. Every 200 operating hours, inspect the wear plates and impeller clearance. The high-chrome components can be rotated or replaced without removing the pump from its mounting bracket. Also, change the hydraulic oil filter on the excavator’s return line more frequently (every 100 hours) when pumping extremely abrasive materials, as fines may bypass the motor’s case drain filter.
Why the 45kW Hydraulic Dredged Pump for Heavy Slurry Outperforms Electric Alternatives
Many contractors assume electric submersible pumps are cheaper upfront, but the 45kW Hydraulic Dredged Pump for Heavy Slurry offers lower total cost of ownership in remote or wet environments. No electrical cables mean zero risk of short circuits or electrocution in standing water. Hydraulic power also provides infinitely variable speed control from the excavator cab, allowing operators to match pump RPM to slurry density. When the intake clogs with debris, reversing the hydraulic motor direction for a few seconds clears the blockage—something no electric pump can do without a complex phase reversal switch. Additionally, the Excavator Mounted Pump for Sand and Mud Removal shares the excavator’s cooling and lubrication system, so there is no separate power pack to maintain or fuel.
