Hydroman® THY Series
Built for the jobs that break ordinary pumps. Excavator-mounted or hydraulically driven high flow sump pump is engineered to keep moving when abrasive ore, dense tailings, and remote terrain make electric pumps impractical — or impossible.
4000 m³/h Max Flow Rate | 70% Max Solids Content | 120 mm Max Particle Size | 80 m Max Head |
Mining environments don't offer second chances. Whether you're transferring copper ore concentrate, clearing a flooded open pit, dredging a tailings pond, or recovering alluvial gold from a river bed, your pump needs to perform without hesitation — every shift, every day, in conditions that would disable lesser equipment.
Hydroman® High Flow Hydraulic Ore Slurry Pumps are purpose-built for exactly this kind of work. Designed around a hydraulic drive that draws power directly from your excavator's existing hydraulic system, these high flow pumps eliminate the need for on-site electrical infrastructure entirely. You bring the machine; it supplies the power. The pump does the rest.
At the core of every Hydroman hydraulic slurry pump is a wear-resistant wetted assembly manufactured from high-chromium alloy — a material widely recognized in the mining industry for its ability to withstand highly abrasive slurries containing silica, iron ore fines, copper concentrates, and coarse aggregate. The impeller geometry is matched to high-density slurry dynamics, not just clean water, which means your flow rates stay consistent even as solids concentrations rise toward the 70% mark.
| $5.24B |
According to Grand View Research, the global mining pumps market generated approximately USD 5.24 billion in revenue in 2025 and is expected to continue growing through 2033, driven by increasing mining activity and ongoing investment in mine water management and slurry transport systems.

What sets the excavator-mounted hydraulic design apart isn't just mobility — it's the combination of mobility and raw capability. Standard electric sludge pumps at this flow capacity require fixed foundations, cable routing, transformer infrastructure, and certified electricians for deployment. A Hydroman hydraulic unit attaches to your excavator arm, travels to the face of the pit, and starts pumping within minutes. On remote copper projects in South America, gold operations in West Africa, or coal dewatering sites across Southeast Asia, that difference in deployment time is measured in days, not hours.
There's a straightforward reason that hydraulic sludge pumps have become the preferred choice for mine dewatering, pit cleaning, and ore transfer in challenging environments: these high volume water pumps remove the electrical dependency that limits where and how fast you can deploy. But the advantages go deeper than infrastructure convenience.
 |  |  |
Your excavator's hydraulic system — typically operating at 200–350 bar and 150–400 L/min flow — provides all the drive power the high flow sump pump needs. No generator, no cable run, no electrical panel. In remote gold mining or riverbed dredging operations, this alone can reduce mobilization time by 60–80%.
|
Electrical hazards in flooded underground mines and saturated open pits are a persistent safety risk. Hydraulic systems are intrinsically safer in these environments — there are no live conductors near standing water, no arc flash risk, and no spark ignition hazard in gassy atmospheres. This is why hydraulic submersible sand pumps are increasingly specified by safety officers in coal mines and underground gold operations.
|
Because the high flow water pump mounts directly onto the excavator arm, the entire pumping unit is repositionable with the machine. In pit dewatering, where the sump location shifts continuously as excavation progresses, this means you reposition in minutes instead of re-plumbing an entire fixed pump installation.
|
 |  |  |
Hydraulic drives transmit torque continuously and smoothly, without the current spikes that occur during electric motor startup. For high-density ore slurry — particularly copper concentrate at 65–70% solids — this matters. Smooth torque delivery reduces high flow hydraulic pump impeller shock loading and extends wear life in abrasive conditions. |
Hydroman hydraulic dredge pumps are compatible with major excavator platforms including Caterpillar, Komatsu, Hitachi, Volvo, and Doosan, with hydraulic connection kits matched to your machine's auxiliary circuit specifications.
|
When you account for the cost of electrical cable, switchgear, grounding systems, and installation labor, a hydraulic pump solution at comparable flow rates typically delivers 40–60% lower installed cost at remote mining sites. The ongoing absence of electrical maintenance tasks compounds those savings over the equipment life cycle. |
Effective mine dewatering is critical for maintaining safe and productive mining operations. Excess groundwater, process water, and slurry accumulation can reduce equipment efficiency, delay production schedules, and increase operational risks. Hydroman® hydraulichigh volume water transfer pumps are engineered to provide reliable pumping solutions for mine dewatering applications, even in remote locations where electrical power is unavailable.
Designed for high solids handling and continuous-duty performance, these hydraulic mining pumps can be mounted on excavators, dredgers, or hydraulic power units to remove water, slurry, sediment, tailings, and abrasive mining waste from pits, tunnels, ponds, and processing facilities.
Open Pit Mine Dewatering Pumps
Open pit mines frequently encounter groundwater infiltration, stormwater accumulation, and slurry build-up that can interrupt production activities. Hydroman® hydraulic submersible pumps with side cutters deliver high flow rates and excellent solids handling capabilities, making them ideal for open pit mine dewatering operations.
The excavator-mounted design allows operators to quickly access flooded areas and remove water mixed with sand, gravel, silt, and mining solids without requiring extensive infrastructure. This flexibility helps mining companies maintain continuous production while minimizing downtime. |  |
 | Underground Mine Dewatering Pumps
Underground mining environments require dependable pumping systems capable of operating safely in confined and difficult-to-access areas. Hydroman® underground mine dewatering pumps are suitable for removing groundwater, drilling fluids, and sediment-laden water from shafts, tunnels, and underground chambers.
Unlike conventional electric pumps, hydraulic high head submersible pumps can operate in wet environments with reduced electrical safety concerns. Their robust construction and abrasion-resistant materials provide reliable performance under harsh underground mining conditions. |
Coal Mine Dewatering Pumps
Coal mining operations often generate large volumes of water containing coal fines, clay, and abrasive particles. Hydroman® coal mine dewatering pumps are designed to transport both water and solids efficiently, reducing the risk of clogging and excessive wear.
The high flow centrifugal pumps can be deployed for pit drainage, wash plant water recovery, slurry transfer, and emergency flood control. High-chrome wear components ensure long service life even when handling highly abrasive coal slurry mixtures.
|  |
 | Quarry and Aggregate Dewatering Pumps
Quarries and aggregate processing facilities require effective water management to maintain productivity and environmental compliance. Hydroman® quarry dewatering pumps can remove water from extraction pits, sedimentation ponds, and aggregate washing systems while simultaneously handling suspended solids.
Their heavy-duty hydraulic drive system allows continuous operation in demanding conditions where conventional pumps may struggle with abrasive materials or fluctuating water levels. |
* High flow capacity for rapid water removal

Mining operators often compare hydraulic slurry pumps and electric slurry pumps when selecting equipment for slurry transfer, mine dewatering, and tailings management. While both technologies can handle abrasive materials, hydraulic pumps offer several advantages in remote and demanding mining environments.
| Feature | Hydraulic Slurry Pump | Electric Slurry Pump |
|---|---|---|
| Power Source | Hydraulic Power Pack or Excavator | Electrical Grid or Generator |
| Mobility | Excellent | Limited |
| Remote Site Operation | Ideal | Requires Power Supply |
| Installation Time | Fast | Moderate |
| Flooded Environment Safety | High | Moderate |
| Excavator Integration | Yes | No |
| Heavy Solids Handling | Excellent | Good |
| Relocation Flexibility | Excellent | Limited |
Hydroman® hydraulic slurry pumps are particularly suitable for mining projects where mobility, reliability, and solids handling performance are critical. Mounted directly on excavators, these THY hydraulic pumps can access areas that are difficult for traditional electric pumping systems to reach.
Hydraulic slurry pumps aren't a general-purpose solution — they're a specialized tool for environments where high solids content, variable particle size, and limited infrastructure access make other pump types inadequate. Here's where Hydroman excavator-mounted pumps deliver their clearest advantage.
Ore Slurry Transfer
Moving copper, iron, nickel, and lithium ore concentrates from the processing face to thickeners or tailing ponds. At solids concentrations of 55–70% by weight, most centrifugal pumps struggle. The THY series hydraulic dredge pumps maintains stable head and flow through these conditions without cavitation or excessive wear. |  |
 | Mine Dewatering
Open-pit and underground mine dewatering pumps must handle not just clean groundwater but silty, sediment-laden water at variable pH. Hydroman hydraulic mine dewatering pumps manage mixed-phase flow — water with suspended fines — without blockage, even when the sump fills with settled sediment between shifts. |
Tailings Pond Dredging
Tailings reclamation and pond management are among the most abrasive pumping duties in the industry. Settled tailings at ponds on copper and gold operations can reach apparent viscosities that stall conventional pumps within hours. High-chromium wetted parts and the THY hydraulic driven dredging pump maintain consistent throughput through even the thickest consolidated tailings layers. |  |
 | Gold Mining & Alluvial Dredging
Alluvial gold operations require pumps that can handle gravel, coarse sand, and clay-bound mineral material simultaneously — often in riverbed or shallow-water environments with no electrical supply for kilometers. Excavator-mounted hydraulic dredge pumps with cutters are the standard tool on major alluvial gold projects in West Africa, Siberia, and South America for exactly this reason. |
Coal Mine Dewatering
Coal seam water management requires pumps rated for gassy underground environments where electrical spark risk is a primary concern. Hydraulic coal mine dewatering pumps eliminate that risk category while delivering the flow rates — typically 500–2,000 m³/h in a longwall operation — needed to keep working faces dry. |  |
 | Quarry & Aggregate Processing
Sand and gravel mining, crushed stone processing, and quarry pit cleaning all generate high-volume slurry flows with coarse particle content. The 120mm maximum particle size rating of the THY series hydraulic pump handles oversize aggregate without strainer fouling, reducing the interruptions that cost quarry operations hours of production time per week. |
Pit Dewatering — Open Cut
Open-cut mining pits collect groundwater, rainfall runoff, and drilling fluid simultaneously. As the pit deepens, the sump location changes and the pump must relocate with it. A hydraulic pump mounted on the pit's dedicated excavator moves with the operation automatically — no separate pump-relocation crew required. |  |
 | Mineral Thickener Underflow
Thickener underflow streams in gold, copper, and nickel processing plants carry some of the highest solids concentrations in any pumping duty — up to 70% solids at elevated temperature. Hydroman's thickener underflow pump configurations are engineered specifically for low-NPSH, high-viscosity slurry conditions at these locations. |
High chromium alloy wetted parts give Hydroman hydraulic slurry pumps broad material compatibility across the full spectrum of hard-rock and soft-rock mining applications. The 27% chromium content in the impeller, liner, and casing achieves a Brinell hardness rating above 600 HB, placing it among the hardest pump materials in commercial production. For context, quartz — the abrasive mineral that destroys most pump liners — has a Mohs hardness of 7; the chromium alloy used in Hydroman wetted parts is engineered specifically to resist it.
Materials routinely pumped through THY series units include: ore slurry (copper, iron, nickel, lithium, gold, coal), mine tailings and tailings pond slurry, coarse sand and gravel, crushed rock fines, bentonite drilling mud, mineral concentrates, industrial sludge, riverbed sediment, pit dewatering water with suspended solids, and dredging spoil.
| 3–5× | Industry testing on high-chromium alloy pump liners in iron ore slurry service shows typical service life 3 to 5 times longer than standard cast iron or rubber-lined equivalents at comparable solids concentrations and flow velocities. This translates directly into fewer scheduled stops and lower total cost of ownership per tonne pumped. |
For highly corrosive mine water — acidic drainage from sulfide ore bodies is a common example — Hydroman's engineering team can specify alternative alloy configurations or supplementary coating treatments to extend service intervals beyond what standard chromium alloy alone achieves.
Mining operations require pumping equipment capable of handling highly abrasive slurries under demanding conditions. Hydroman® hydraulic submersible slurry pumps have been successfully deployed in mining, dredging, tunneling, and tailings management projects worldwide.

| Customizable Configurations
Options including agitators, cutter heads, jet rings, side cutters, wear-resistant materials, and hydraulic power packs allow each pump system to be tailored to specific mining conditions.
|
The base THY pump is a high-performance hydraulic slurry pump. The accessories listed below are what transform it into a complete mining pump system — capable of breaking up consolidated sediment, maintaining suction in shallow water, monitoring performance remotely, and operating independently of any host excavator when needed.
A hydraulic agitator extends suction reach into consolidated slurry beds. Side cutters and cutter heads break up compacted sediment and coarse aggregate ahead of the suction inlet. The jet ring system induces high-velocity fluid jets at the suction to liquefy settled solids and maintain pumpability. Wear-resistant suction strainers protect the impeller from oversize debris without restricting flow. A hydraulic power unit provides independent drive power for applications where an excavator isn't the host machine. Floating dredging platforms allow full aquatic deployment for tailings pond operations. A remote monitoring system closes the loop on flow rate, pressure, and pump health for centralized mine management systems.
| Hydraulic Agitator | Side Cutters | Cutter Head | Jet Ring System | Wear-Resistant Suction Strainer |
| Hydraulic Power Unit (HPU) | Floating Dredging Platform | Remote Monitoring System | Custom Mounting Frame | HDPE Discharge Pipework |
Specifications on paper only mean something if they hold up under actual mining conditions. Below are three representative project types where Hydroman hydraulic ore slurry pumps have delivered measurable operational improvements.
Copper Mine — Slurry Transfer Project High-Density Copper Concentrate, South American Open Pit
The operation required continuous transfer of copper ore slurry at 62% solids by weight from the primary classifier to a tailings thickener 380 meters away, with a static head requirement of 34 meters. Previous electric pump installations had experienced impeller wear failures every 6–8 weeks due to the abrasive silica content of the ore body. The 300THY hydraulic sand pump, equipped with 27% high-chromium alloy wetted parts, achieved a 14-week continuous run between planned inspections under the same service conditions, reducing unplanned downtime by approximately 65% and annual parts cost by 40%.
Result: 65% reduction in unplanned downtime · 40% lower annual parts cost |  |
 | Gold Mining — Alluvial Dredging Project
Riverbed Dredging, West African Alluvial Gold Operation
A mid-scale alluvial gold operation needed a pumping solution capable of handling riverbed gravel up to 80mm in particle size mixed with clay-rich sediment at variable water depth, in a location 190 km from the nearest power grid. A 200THY excavator-mounted hydraulic dredge pump with hydraulic agitator and jet ring system was deployed on a 20-tonne excavator. Daily throughput increased by 35% compared to the contractor's previous suction dredge arrangement, with the excavator-mounted configuration allowing the team to follow the productive gravel layer as it shifted laterally — something a fixed-position dredge couldn't do.
Result: 35% increase in daily throughput · Full off-grid operation · No electrical infrastructure |
Tailings Pond — Reclamation Project
High-Volume Tailings Reclamation, Nickel Operation
A tailings pond reclamation project required dredging and transporting 1.2 million cubic meters of consolidated tailings over a 12-month program, with pipeline distances up to 1.8 km. Two 350THY hydraulic pump units , each mounted on an amphibious excavator and deployed on floating pontoons, maintained a combined continuous flow rate of approximately 3,800 m³/h through a shared pipeline system. The hydraulic drive configuration allowed both units to operate in areas of the pond where submerged electrical equipment would have required additional hazardous area certification and protection measures.
Result: 1.2M m³ reclaimed on schedule · Dual-unit 3,800 m³/h sustained flow · No electrical hazard zone requirements |  |
The three primary selection inputs are your required flow rate (m³/h), your total dynamic head (static head plus friction losses in your pipeline), and your slurry's solids concentration and D85 particle size. Share these with our engineering team and we'll provide a model recommendation with a performance curve specific to your conditions. If you don't have all the data yet, we can help you calculate what you need.
THY series pumps are designed to work within the auxiliary hydraulic circuit specifications of standard construction excavators. Typical operating requirements are 200–350 bar pressure and 150–400 L/min flow, depending on model size. Your excavator's specifications will be reviewed at the time of order to confirm compatibility and select the correct hydraulic motor configuration.
Yes. A dedicated hydraulic power unit (HPU) can be supplied as an alternative drive source, allowing the pump to operate independently on a pontoon, barge, or fixed mounting. The HPU is diesel-powered and sized to match the specific pump model's hydraulic demand. This is the standard configuration for tailings pond dredging operations where a full-time dedicated excavator isn't available.
Wear life varies significantly based on slurry abrasivity, flow velocity, and solids concentration. In copper ore service at 55–65% solids, high-chromium impellers and liners typically achieve 800–1,400 operating hours between planned replacements — roughly 3 to 4 times the wear life of standard cast iron components in the same service. We recommend establishing an initial inspection interval at 600 hours for new installations, then adjusting based on actual wear measurements.
Yes. Hydroman maintains stock of critical wear components — impellers, liners, seals, and bearing assemblies — across all THY series models. Parts can be dispatched internationally with standard lead times of 5–15 business days for in-stock items. For major mining operations requiring on-site support, our technical team is available for installation commissioning and operator training.
The terms are often used interchangeably in the industry, but there's a practical distinction: slurry pumps are designed for higher solids concentrations with coarser, more abrasive particles (ore, gravel, sand), while sludge pumps are typically optimized for finer, higher-viscosity material like biological sludge, thickened tailings, or industrial process waste. The THY series covers both categories — contact us with your material's particle size distribution and viscosity if you're uncertain which configuration applies.
Yes. Standard high-chromium alloy wetted parts provide moderate resistance to mildly acidic conditions (pH 4–6). For highly acidic mine drainage — common in sulfide ore bodies where pH can fall below 3 — alternative material configurations including duplex stainless steel or specially coated chromium alloy components are available. Specify your drainage chemistry when inquiring and we'll recommend the appropriate material package.
Several types of pumps are used throughout mining operations, including slurry pumps, dewatering pumps, centrifugal pumps, gravel sand pump, submersible pumps, and hydraulic slurry pumps. The selection depends on the material being handled and site conditions. For abrasive slurries containing ore particles, tailings, sand, or gravel, heavy-duty hydraulic slurry pumps are often preferred because they provide superior solids handling capability and excellent wear resistance in demanding mining environments.
An ore slurry pump is a specialized pump designed to transport mixtures of water and mineral solids generated during mining and mineral processing operations. Unlike standard water pumps, ore slurry pumps feature abrasion-resistant materials, heavy-duty impellers, and reinforced wear components capable of handling high concentrations of solids. They are commonly used in gold mining, iron ore processing, copper mining, and tailings transportation systems.
The best mine dewatering pump depends on the application, pumping distance, solids content, and site accessibility. For remote mining locations or areas without reliable electrical infrastructure, hydraulic slurry dewatering pumps offer significant advantages. They can remove water containing sediment, sand, coal fines, and other abrasive particles while maintaining high reliability and operational flexibility.
Yes. Hydroman® hydraulic slurry pumps are specifically designed to handle abrasive mine tailings, mineral concentrates, and high-density slurries. High-chrome wear components and heavy-duty construction enable the pumps to transport tailings efficiently while minimizing wear. Optional agitators and cutter attachments further improve solids suspension and pumping performance.
Both pump types are designed to handle abrasive solids, but their primary applications differ. Dredge pumps are commonly used for sediment removal, river dredging, and sand extraction, while mining slurry pumps are optimized for transporting ore slurries, tailings, process water, and mining waste. Hydroman® hydraulic slurry pumps can often be configured for both dredging and mining applications depending on project requirements.
Wear life varies depending on slurry concentration, particle size, operating hours, and pumping conditions. In many mining applications, high-chrome wear parts can provide several times the service life of standard cast iron components. Proper pump selection, routine inspection, and operating within recommended performance ranges can significantly extend component lifespan and reduce maintenance costs.
Share your application details — flow requirement, head, slurry type, solids content, and excavator model — and Hydroman's engineering team will recommend the right THY series hydraulic pump with a site-specific performance curve and quotation.
