Hydroman 14 Pump Description
When your dredging project demands brute force against dense, packed sludge, Hydraulic Excavator Mounted Dredge Pump for Thick Mix is not a luxury—it is a necessity. The Hydroman® 350THY220-6P functions as a 350THY220 Hydraulic Submersible Dredge Pump for Slurry, engineered specifically for vertical underwater deployment. This 14 Inch Excavator Dredging Pump with Side Cutters delivers unmatched performance in moving slurries with up to 70% solids content. Built as a Heavy Duty Hydraulic Slurry Pump for Underwater Dredging, it thrives where standard pumps stall. Understanding the 350THY220 means recognizing that it is a High Power 220kW Dredge Pump for Tough Slurry, designed to maximize your existing excavator’s hydraulic power while minimizing maintenance downtime.
Its vertical deployment capability. Unlike horizontal pumps that struggle with suction lift limits, the Hydroman® 350THY220-6P submerges completely into the slurry, pulling material directly into its intake. This eliminates priming issues and allows operators to reach depths that are simply inaccessible to other pump types, making it the go-to Vertical Submerged Dredge Pump for Thick Sludge Removal in deep settling lagoons and underwater mining pits.
Seamlessly. This Excavator Hydraulic Pump for Dredging Thick Materials attaches directly to the boom arm of 20+ tonne excavators (Case, Caterpillar, Komatsu, etc.), tapping into the machine’s existing auxiliary hydraulic system. There is no need for separate power units or complex electrical rewiring, which significantly reduces deployment time and operational overhead.
Hydraulic drive delivers higher torque density in a compact footprint. A High Power 220kW Dredge Pump for Tough Slurry generates exceptional starting torque to fluidize settled solids instantly, while hydraulic systems remain immune to water ingress damage. This makes the 350THY220 inherently more reliable for full-submersion duties in harsh marine or mining environments.
3 Distinct Design Features of the Hydraulic Excavator Mounted Dredge Pump for Thick Mix
Feature 1: High-Chromium Alloy Construction for Abrasion Resistance. The pump casing, impeller, and agitator components are cast from premium high-chromium alloy, specifically formulated to withstand the relentless wear caused by sand, gravel, mine tailings, and sharp debris. This material selection dramatically extends service intervals and reduces total cost of ownership in high-solids applications.
Feature 2: Dual Side Cutters for Aggressive Material Breakdown. As a true 14 Inch Excavator Dredging Pump with Side Cutters, the 350THY220-6P is equipped with two robust hydraulic-driven side cutters positioned at the intake. These cutters mechanically chew through compacted crusts, fibrous sludge mats, and settled clay, transforming thick, immovable layers into fluid slurry that flows freely into the pump.
Feature 3: Integrated Agitation Mechanism for Non-Clog Operation. Beneath the main impeller, an auxiliary agitation impeller generates powerful turbulent flow. This lifts settled sediments directly into the suction zone, preventing the formation of dead zones or blockages. This agitation capability is the primary reason the Hydraulic Excavator Mounted Dredge Pump for Thick Mix maintains consistent flow even when dealing with the most viscous, debris-laden materials.
This 350THY220 Hydraulic Submersible Dredge Pump for Slurry operates across a wide performance envelope. With a 14-inch (350mm) discharge diameter, it handles solids up to 120mm in size without clogging. Flow rates reach up to 975 cubic meters per hour at heads ranging from 18 to 26 meters, depending on configuration and slurry density. The 220kW hydraulic motor provides variable speed control directly from the excavator cab, allowing operators to fine-tune output to match changing site conditions in real time.
When deployed as a Heavy Duty Hydraulic Slurry Pump for Underwater Dredging, the unit remains fully submerged at depths far exceeding conventional pump limits. Hydraulic hoses transmit power from the excavator to the pump motor, eliminating any electrical components underwater. This design choice dramatically enhances job site safety while enabling continuous operation in wet, hazardous environments where electric pumps would present unacceptable risks.

Mining Tailings Management & Thick Sludge Removal
In mining operations, tailings ponds and settling basins accumulate dense, highly abrasive sludge that traditional pumps refuse to handle. The Hydroman® 350THY220-6P, configured as a Vertical Submerged Dredge Pump for Thick Sludge Removal, submerges directly into these ponds to extract iron ore tailings, gold mine waste, coal slurry, and bauxite residue. The dual side cutters break up settled crusts while the agitation mechanism maintains a consistent, pumpable slurry density of up to 70% solids by weight. Operators drastically reduce pond cleanup cycles and recover valuable materials that would otherwise remain permanently settled.
Furthermore, this Excavator Hydraulic Pump for Dredging Thick Materials proves indispensable for draining and cleaning thickener underflows, mill scale sumps, and flotation area collection pits. Its ability to work at variable depths—up to 120 meters with appropriate hose lengths—means no pond is too deep or too thick to be effectively remediated.
Heavy Construction & Industrial Sludge Pumping
For heavy civil contractors and industrial facilities, removing thick sludge from confined spaces presents a recurring challenge. Whether cleaning out anaerobic digesters, dredging marinas and harbors, or dewatering deep caissons and intake towers, the Hydroman® 350THY220-6P delivers where other methods fall short. The pump attaches directly to the excavator boom, offering pinpoint placement in areas that cannot accommodate traditional dredging barges or crane-suspended pumps.
In construction applications such as pipeline trench dewatering and overburden removal, the High Power 220kW Dredge Pump for Tough Slurry moves silt-laden water and gravel slurries with equal efficiency. The vertical submerged configuration allows operators to pump directly to disposal areas via discharge hoses, eliminating the need for intermediate transfer equipment and significantly accelerating project timelines.
Frequently Asked Questions (FAQ)
Q1: Can I use the 350THY220 Hydraulic Submersible Dredge Pump for Slurry in saltwater environments?
Yes. The high-chromium alloy composition provides excellent corrosion resistance in both fresh and saltwater applications. Hydroman® can also supply pumps constructed from Duplex 2205 or CD4MCu alloys for extremely aggressive chemical or high-chloride environments.
Q2: What excavator size is required to power the Hydraulic Excavator Mounted Dredge Pump for Thick Mix?
The 350THY220-6P is optimally paired with excavators in the 20 to 35 tonne class. However, Hydroman® provides custom mounting brackets and hydraulic flow regulation to ensure compatibility across a wide range of machine sizes and brands.
Q3: How does the 14 Inch Excavator Dredging Pump with Side Cutters handle large debris without clogging?
The combination of oversized volute passages (120mm maximum particle clearance), dual side cutters for pre-shredding, and the bottom agitation impeller creates a three-stage defense against blockages. Solidi are first cut, then suspended, and finally drawn through generously sized internal channels, virtually eliminating clog-related downtime.
