Hydroman 350THY200-6 Sluge Pump Description
When your oxidation pond is choked with compacted biosolids and abrasive sludge, an ordinary pump simply won‘t survive—let alone deliver results. This is where the Hydroman® 350THY200-6P, a 14 Inch Hydraulic Dredge Pump for Sludge Removal, transforms your excavator into a purpose-built dredging weapon. Designed as an Excavator Driven Submersible Sludge Pump for Ponds, it operates fully underwater, pulling high-density slurry directly through a 200mm discharge line. Built specifically as a Vertical 350mm Submerged Pump for Oxidation Sludge, it tackles the thickest settled layers. As a Hydraulic Excavator Dredge Pump for Waste Sludge, it leverages your excavator‘s existing hydraulic power, eliminating the need for external electrical hookups. Above all, this Heavy Duty Submersible Pump for Oxidation Ponds combines brute force with surgical precision.
The Hydroman® 350THY200-6P is a high-performance hydraulic submersible centrifugal pump engineered specifically for excavator mounting. Unlike standard dewatering pumps that choke on solids, this pump features an integrated agitator that fluidizes settled material at the intake, allowing the pump to draw slurries with solid concentrations up to 70% by weight. With a 350mm (approx. 14-inch) discharge and a 200mm outlet that handles particles up to 60mm in size, it moves volumes that smaller pumps cannot touch. The pump is powered directly by your excavator’s auxiliary hydraulic circuit (or a separate hydraulic power pack), giving you variable speed control and instant responsiveness from the operator‘s seat. Every component that contacts sludge is constructed from high-chrome abrasion-resistant alloy, designed to withstand years of punishment in grit-filled oxidation environments. With flow tests confirming capacities in the range of 350–420 m³/h (approximately 1,500–1,850 GPM), this is not a pump for small jobs—it‘s a production dredging tool.
5 Design Features That Define the Hydroman® 350THY200-6P
Integrated agitator for high-concentration dredging – A double-blade agitator mounted directly above the suction intake continuously breaks up settled solids, allowing the pump to move high-density slurries rather than wasting energy on clear water.
High-chrome abrasion-resistant wet ends – All major wear components—impeller, casing, and agitator—are cast from high-chrome alloy, providing exceptional resistance to sand, grit, and abrasive sludge particles found in mature oxidation ponds.
Hydraulic-driven with variable RPM control – The pump uses a robust hydraulic motor powered by your excavator‘s existing system, offering infinitely adjustable pump speed from the cab for precise control over dredging intensity.
Vertical submersible design—no priming required – Unlike self-priming pumps that struggle with suction lift, the Hydroman® operates fully submerged, eliminating priming issues and maintaining consistent flow even at variable pond depths.
Excavator boom integration via bucket linkage – Mounts directly to your excavator‘s boom using standard bucket pins, allowing the operator to position the pump with pinpoint accuracy while keeping the discharge hose routed along the stick and boom for clean operation.

Excavator Mounted Vertical Sludge Pump for Ponds in Wastewater Treatment
Oxidation ponds in wastewater treatment facilities accumulate organic solids year after year, forming layered crusts at the surface and compacted sludge blankets at the bottom. Traditional methods—manual cleanouts, vacuum trucks, or floating dredges—are slow, expensive, and often leave significant residual deposits. The Hydroman® 350THY200-6P, configured as an Excavator Mounted Vertical Sludge Pump for Ponds, addresses this problem directly from the bank or within the pond basin.
An excavator fitted with this pump can walk down the pond bank, lower the pump into the sludge layer, and begin removing material within minutes of arrival on site. The operator uses the excavator‘s boom to gently traverse the pump across the sludge blanket at variable depths, while the discharge hose sends slurry directly to a dewatering bag, holding tank, or drying bed. Because the pump is hydraulically powered by the excavator itself, there are no generators, extension cords, or separate power units to manage. This single-machine, one-operator approach dramatically reduces labor costs, eliminates multiple equipment moves, and allows targeted sludge removal where it is needed most—leaving the rest of the pond undisturbed.
Industrial Hydraulic Sludge Pump for Underwater Dredging in Mining and Industrial Settling Ponds
Beyond municipal wastewater, the Hydroman® 350THY200-6P excels as an Industrial Hydraulic Sludge Pump for Underwater Dredging in mining tailings ponds, coal ash settling basins, and industrial lagoons. These environments present a uniquely punishing combination of high-density solids, acidic or alkaline water chemistry, and irregular basin geometries that defeat conventional pumping systems.
The pump‘s high-chrome wet ends resist the abrasive attack of silica sand, magnetite fines, and crushed ore particles that would destroy standard cast iron pumps in a matter of days. The hydraulic drive system has no electrical components submerged in the pond, eliminating the risk of short circuits, burnt windings, or explosion hazards in potentially combustible environments—a critical safety advantage in coal handling areas or chemical settling ponds.
The vertical submersible configuration allows the pump to access deep settling basins where the sludge blanket may be 10, 20, or even 30 feet below the surface, with no reduction in suction performance. For mine sites that need to reclaim settlement capacity in tailings ponds or transfer thickened slurry to dewatering circuits, the Hydroman® 350THY200-6P provides a mobile, powerful, and immediately deployable solution that requires no permanent infrastructure.
Frequently Asked Questions
Q1: What excavator size and hydraulic flow are required to operate the Hydroman® 350THY200-6P?
A: The Hydroman® 350THY200-6P typically requires an excavator in the 20–30 ton class with an auxiliary hydraulic flow rate between 106–130 L/min (approximately 28–34 GPM) at operating pressures of 250–300 bar. The pump‘s hydraulic motor consumes this flow to deliver the rated speed and torque, so confirmation of your excavator‘s hydraulic specifications prior to ordering is recommended. Most standard excavators from Caterpillar, Komatsu, Hitachi, Volvo, and Deere in this weight class can support the pump with their existing auxiliary circuits.
Q2: What is the maximum discharge distance the pump can achieve when dredging oxidation pond sludge?
A: With a 200mm (8-inch) discharge line properly sized and laid, the Hydroman® 350THY200-6P can achieve total dynamic head up to approximately 23 meters—which translates to horizontal pumping distances exceeding 500 meters over reasonably flat terrain, depending on pipe diameter, elevation changes, and slurry density. For longer distances or uphill pumping, a booster pump or power pack with higher pressure output may be required. The sales team can model your specific pond topography and disposal location to recommend the optimal configuration.
Q3: Can the Hydroman® 350THY200-6P handle sludge with large debris or rag content?
A: The standard agitator configuration is optimized for sludge, silt, sand, and biosolids with particle sizes up to 60mm. For applications involving fabric scraps, heavy rag content, or fibrous solids, the pump can be equipped with optional cutter heads that shred material before it enters the suction intake. These cutters use interchangeable hardened teeth to reduce wear costs and prevent clogging in challenging wastewater environments. For lagoon applications with extreme debris, consult the engineering team to select the appropriate cutter or chopper configuration.
Ready to Restore Your Oxidation Pond Capacity?
The Hydroman® 350THY200-6P is not a theoretical solution—it is field-proven technology that wastewater plant operators, mine superintendents, and environmental contractors rely on year after year.
