Hydroman® Headcutter Pump Description
When tackling tough underwater sand removal projects, operators need reliable equipment that won't clog or wear out prematurely. The Hydroman 100THY22 Hydraulic Sand Pump with Headcutter delivers exactly that—a powerful combination of a 4 Inch Hydraulic Submersible Sand Dredging Pump and a heavy-duty cutter head. This 100mm Discharge Excavator Hydraulic Slurry Pump mounts directly onto your existing machinery, transforming it into a high-production dredging unit. As a Hydraulic Driven Sand Pump with Cutter Head, it excels at breaking up compacted sand, gravel, and clay that standard pumps cannot handle. The Vertical Submersible Hydraulic Pump for Sand Removal design allows continuous operation while fully submerged, making it ideal for deep excavation sites.
Unlike electric submersible pumps that require separate power sources and complex cable management, this 22kW Excavator Mounted Hydraulic Dredging Pump draws power directly from your excavator's auxiliary hydraulic circuit. The integration of a rotating cutter head at the intake distinguishes this unit from basic agitator pumps. While standard slurry pumps rely solely on suction, the Hydroman® system actively excavates material before it enters the pump chamber.
The cutter head breaks hard-packed layers—often formed by settling or compaction over time—into manageable chunks. These chunks then pass through the 4 Inch Hydraulic Submersible Sand Dredging Pump impeller, which is cast from high-chrome alloy for maximum abrasion resistance. The result is a continuous, high-density slurry that minimizes water usage while maximizing solids transport.
Design Features of the 4 Inch Hydraulic Submersible Sand Dredging Pump
Engineered for extreme duty cycles, the Hydroman 100THY22 Hydraulic Sand Pump with Headcutter incorporates several field-proven design elements:
Hi-Chrome wear components – The impeller, suction plate, and cutter blades are manufactured from A05 chrome alloy, achieving 550+ BHN hardness to resist sand erosion.
Dual mechanical seal system – An oil bath chamber protects the hydraulic motor from water ingress, even during prolonged submersion.
Cartridge-type cutter assembly – Replaceable carbide-tipped teeth on the Hydraulic Driven Sand Pump with Cutter Head allow quick field replacement without removing the pump from the excavator.
Integrated agitator nozzle – Auxiliary water jets help fluidize settled material before the cutter head engages, reducing hydraulic power demands.
100mm flanged discharge – The 100mm Discharge Excavator Hydraulic Slurry Pump outlet accepts standard dredge hoses and quick-couplers for rapid setup changes.
Each pump undergoes pressure testing to verify seal integrity before leaving the Hydroman® facility. The vertical orientation ensures that even when operating in water depths up to 30 meters, the hydraulic motor remains properly lubricated and cooled.

While this pump handles numerous dredging scenarios, two applications consistently demonstrate its superiority over conventional methods.
Dredging Settling Ponds in Mining Operations
Mining sites generate vast quantities of tailings and sediment that settle rapidly in holding ponds. Traditional dredging requires draining the pond, bringing in long-reach excavators, and hauling material by truck—a slow, expensive process. The 22kW Excavator Mounted Hydraulic Dredging Pump works while the pond remains full.
An operator positions the excavator on the bank, lowers the pump into the slurry, and begins pumping directly to a dewatering facility or disposal area. One Australian iron ore mine reported reducing pond cleanout time from three weeks to four days after switching to this Hydroman® system.
Emergency Levee Repair and Flood Control
When floodwaters breach or threaten levees, every hour matters. The Underwater Hydraulic Sand Pump with Agitator Cutter deploys rapidly because it requires no external power source beyond the excavator's hydraulic system. Crews can pump sand from submerged borrow pits directly into geotextile tubes or sandbags positioned along the breach.
The cutter head breaks through crusted layers that would otherwise block a standard suction hose. During Mississippi River flood operations, contractors successfully filled 200-foot geotubes in under six hours using this Vertical Submersible Hydraulic Pump for Sand Removal.
FAQs About the Hydraulic Driven Sand Pump with Cutter Head
No. The 4 Inch Hydraulic Submersible Sand Dredging Pump has a maximum spherical solids passage of 32mm (1.25 inches). Rocks larger than this should be removed by the excavator bucket before pumping. However, the cutter head effectively breaks up clay balls, compacted sand, and soft shale that would otherwise bridge across the intake.
The pump requires 70-110 L/min (18-29 GPM) at 180-210 bar (2600-3050 PSI). Most 12-ton to 20-ton excavators meet these specifications. Hydroman® provides flow control valves to match pumps to lower-flow machines, though this reduces production rates proportionally.
The standard hydraulic hose length allows operation at 15 meters (50 feet) below the excavator's hydraulic swivel. Extended hose packages are available for depths up to 30 meters (100 feet). The pump body withstands external pressure at these depths, but operators must verify that return line backpressure does not exceed the excavator's case drain specifications.
Why Choose This Underwater Hydraulic Sand Pump with Agitator Cutter Over Electric Alternatives?
Electric submersible slurry pumps require high-voltage cables, starters, and often a generator barge. The Hydroman 100THY22 Hydraulic Sand Pump with Headcutter eliminates these components entirely. Your excavator already has the power source—you simply plug into the auxiliary circuit. This portability means one truck transports both the excavator and the pump to any job site.
Maintenance also favors hydraulic systems. When an electric pump motor fails, the entire unit must be pulled to a repair shop. With this Hydraulic Driven Sand Pump with Cutter Head, the hydraulic motor and pump end are separate modules. A mechanic can replace either component on-site in under two hours using common hand tools. The high-chrome wear parts typically last 800-1200 hours in abrasive sand applications, compared to 300-400 hours for cast iron pumps.
Hydroman® 100THY22-6P Hydraulic Sand Pump with Headcutter features 100mm (4 inch) discharge and 22kW power. This vertical submersible excavator hydraulic driven pump delivers efficient sand removal with cutter agitation. Whether you need to clean settling ponds, restore marina depths, or fill geotubes for shoreline protection, this pump system outperforms conventional methods in speed, reliability, and operating cost.
