Jet Ring Pump Description
The Hydroman 100THY11 Hydraulic Slurry Pump for Excavator is a Vertical Hydraulic Dredging Pump for Abrasive Slurry Handling designed to tackle the toughest dredging jobs. This Heavy Duty Submersible Pump with High Chrome Agitator operates as an Excavator Mounted Hydraulic Pump for Underwater Slurry Removal, delivering unmatched performance in high-density solids environments. As a Hydraulic Driven Slurry Pump for Mining and Dredging, it represents a significant upgrade from conventional electric submersible pumps.
But what exactly makes this pump different from standard slurry pumps? And why should mining and dredging professionals consider it for their toughest jobs?
The Hydroman® 100THY11-6P is a Hydraulic Driven Slurry Pump for Mining and Dredging engineered for extreme durability. Unlike standard pumps that rely on electric motors, this unit draws power directly from an excavator‘s hydraulic system or a standalone hydraulic power pack. This design eliminates the need for complex electrical cabling and reduces the risk of motor burnout in wet environments.
The pump operates as a Vertical Hydraulic Dredging Pump for Abrasive Slurry Handling, meaning it is designed to be submerged vertically in water, sumps, pits, or tailings ponds. Its vertical orientation allows it to reach deep sediment layers and maintain continuous suction without priming issues.
What sets this pump apart from conventional submersible pumps is its dual-action material disruption system. It combines a high-chrome agitator with a high-pressure water jet ring, allowing it to break up compacted, dry, or clay-rich materials that would quickly clog standard pumps. This makes it particularly effective in applications where conventional suction pumps fail entirely.
Design Features of the Heavy Duty Submersible Pump with High Chrome Agitator
The Heavy Duty Submersible Pump with High Chrome Agitator incorporates several engineering innovations that contribute to its longevity and performance in abrasive environments.
All flow-wearing components, including the impeller, volute casing, and agitator blades, are manufactured from high-chrome alloy. This material is specifically formulated to withstand the punishing effects of sand, gravel, ore particles, and tailings. High chrome wear parts offer significantly longer service life compared to standard cast iron or steel components, reducing replacement frequency and lowering total cost of ownership.
The pump is powered by a robust hydraulic motor that delivers consistent high torque across a wide range of operating conditions. Unlike electric motors, which can overheat or trip when handling heavy loads, hydraulic motors maintain steady power delivery even when the pump is fully submerged in thick, viscous slurries. The hydraulic system also allows for variable speed control, giving operators precise command over pumping rates.
The excavating action is created by hardened high-chrome agitator blades mounted directly below the pump suction inlet. These blades rotate to create a current that lifts settled sediments and conveys them directly to the impeller intake. This continuous flow of solids prevents material buildup and ensures consistent slurry concentration at the discharge point.
Mounted on the suction strainer, the water jet ring contains multiple high-pressure spray nozzles. When activated by a small auxiliary pump, these nozzles direct powerful jets of water into compacted material beds. The high-pressure water breaks up densely packed or consolidated materials—including hard clay, compacted sand, and dry tailings—making them easier to fluidize and feed into the pump. This system works in conjunction with the agitator to create a powerful pumping system capable of moving thick mud through long discharge pipelines without additional booster pumps.
The pump operates at a relatively low rotation speed compared to conventional slurry pumps. This design choice reduces wear on internal components, extends service intervals, and improves energy efficiency. Lower rotational speeds also mean less turbulence within the pump casing, which helps maintain stable slurry flow and reduces the risk of air entrainment.
The Hydraulic Driven Slurry Pump for Mining and Dredging can handle up to 70% solids by weight, making it one of the most capable pumps in its class for high-density slurry applications. This capability is critical for mining operations, tailings management, and sand extraction projects where maximizing solids concentration directly impacts productivity and profitability.
Despite its heavy-duty capabilities, the pump features a compact footprint that allows it to be easily transported and deployed. It can be suspended from an excavator boom, cable-hung from a crane, or mounted on a floating platform with minimal modification. This versatility makes it suitable for projects ranging from small-scale pond cleanups to large-scale dredging operations.

Mining and Tailings Management
The Hydroman® 100THY11-6P is widely deployed in mining environments where conventional pumps fail due to high solids concentration and abrasive particle content. The pump is used to manage tailings, transfer ore slurries, clean settling tanks, and recover valuable minerals from process streams.
In hard rock mining operations, the pump excels at extracting gold, coal, iron ore, and copper concentrates from sumps and collection points. The combination of high-chrome wear parts and hydraulic drive ensures continuous operation even when handling slurries containing sharp, angular particles. The water jet ring system is particularly valuable in tailings ponds, where fine solids tend to compact over time and resist fluidization.
Typical mining applications include:
Pumping mill discharge slurries to cyclones and concentrators
Cleaning out thickener underflow sumps
Reclaiming settled solids from tailings storage facilities
Transferring abrasive slurries between process stages
Dewatering mine pits and underground workings
The pump’s ability to operate at depths up to 250 meters makes it suitable for deep mining applications where access is limited and electrical equipment would pose safety concerns.
Dredging and Sand Extraction
When attached to the boom of a hydraulic excavator, the 100THY11-6P functions as a highly mobile dredging system. This configuration eliminates the need for dedicated dredging vessels, significantly reducing capital and operating costs for small to medium-scale dredging projects.
The pump is particularly effective in:
Harbor and marina dredging: Removing accumulated sediment from shipping channels and berthing areas without disrupting vessel traffic.
River and lake cleanup: Extracting nutrient-rich sediment, silt, and debris from freshwater bodies to restore water quality and navigability.
Beach reclamation: Pumping sand from offshore borrow areas to eroding beaches for coastal restoration projects.
Sand and gravel mining: Extracting construction aggregates from submerged deposits with high efficiency and minimal environmental disturbance.
Frequently Asked Questions (FAQ)
The water jet ring system is essential for applications involving compacted, dry, or clay-rich materials that resist fluidization. Standard suction pumps often become clogged or lose prime when attempting to pump these materials because the solids cannot be adequately suspended. The high-pressure nozzles on the jet ring inject water directly into the compacted bed, breaking up agglomerated particles and creating a fluidized mixture that can be easily drawn into the pump intake. This dual-action approach—mechanical agitation from the high-chrome agitator combined with hydraulic disruption from the jet ring—ensures continuous production even in the most challenging material conditions.
The pump is designed to be compatible with most standard hydraulic excavators, but proper matching of hydraulic flow and pressure is essential for optimal performance. The 100THY model typically requires an excavator with auxiliary hydraulic flow in the range of 60-140 gallons per minute (GPM) at pressures between 2,100 and 3,000 psi. Before deployment, operators should verify their excavator‘s hydraulic specifications against the pump’s requirements. For excavators that fall outside these ranges, Hydroman offers alternative models and can provide standalone hydraulic power packs as an alternative power source.
High-chrome wear parts are designed to provide extended service life, but regular inspection and timely replacement are still necessary. Operators should inspect the agitator blades, impeller, and volute casing for signs of wear after every major pumping campaign. The frequency of replacement depends on the abrasiveness of the material being pumped—sand and gravel will wear components faster than fine silt or organic sludge. As a best practice, maintain an inventory of critical wear parts on site to minimize downtime when replacements are needed. Low rotation speed operation and proper hydraulic flow matching also contribute significantly to wear part longevity.
