Additionally, the Vertical 4 inch Hydraulic Dredge Pump with Jet Ring offers an alternative configuration for compacted soil applications. This is a Heavy Duty Hydraulic Pump for Sand Slurry, built to last where electric pumps fail. The Hydraulic Suction Pump for Underwater Sand operates fully submerged, powered directly by the excavator's hydraulic system without any external electrical connections.
Key Design Features of the Hydroman® Excavator Hydraulic Sand Pump for Dredging
The Hydroman® 100THY Hydraulic Suction Sand Pump and its 150THY15 counterpart are engineered with several distinct design advantages that set them apart in the industrial dredging market.
High-Chrome Abrasion-Resistant Construction
All wear parts, including the impeller, volute liner, and agitator, are manufactured from premium high-chrome alloy. This material choice provides exceptional resistance to the erosive wear caused by sand, gravel, and other abrasive solids. In field applications, this translates to significantly extended service intervals and lower total ownership costs compared to standard cast iron or rubber-lined pumps.
Built-in Hydraulic Agitator System
A key differentiator is the integrated high-efficiency agitator mounted at the base of the pump. As the hydraulic motor drives the agitator, it continuously lifts and stirs settled solids from the bottom, creating a dense, fluidized slurry. This active agitation prevents the formation of sand bridges and ensures a steady, high-concentration feed into the pump intake. The result is the ability to achieve slurry densities of up to 70% solids by weight—far exceeding what conventional suction-only pumps can deliver.
Excavator-Driven Hydraulic Power
Unlike electric submersible pumps that require generators, long power cables, and strict voltage compatibility, this pump is powered directly by the excavator's existing auxiliary hydraulic circuit. There are no cables to manage, no electrical hazards in wet environments, and no dependency on grid power. The operator can simply drive the excavator to the job site, attach the pump in place of the bucket, and begin dredging immediately. For applications where an excavator is not available, the same pump can be powered by a standalone hydraulic power pack.
Large Solids Handling and Non-Clog Design
The 6 Inch Submersible Hydraulic Pump for Sand Removal features generously sized internal flow passages and a recessed impeller design that allows it to pass solids up to 5 inches (approximately 120mm) in diameter without clogging. This capability is critical in dredging environments where debris, rocks, and organic matter are commonly encountered. Downtime caused by blockages is virtually eliminated, keeping projects on schedule and within budget.
Optional Jet Ring and Side Cutter Attachments
For challenging conditions involving compacted sand, sticky clay, or hard-packed sludge, the pump can be equipped with a Vertical 4 inch Hydraulic Dredge Pump with Jet Ring configuration or side cutter attachments. The jet ring directs high-pressure water jets around the pump intake to fluidize dense materials, while side cutters mechanically break up consolidated sediments before they enter the pump.
Superior Sealing and Submersion Capability
The hydraulic motor and pump shaft are protected by a multi-stage mechanical seal system with an oil bath chamber. This design prevents water and abrasive particles from penetrating the critical internal components, allowing the pump to operate reliably while fully submerged at significant depths. Corrosion-resistant materials and coatings further enhance durability in both freshwater and saltwater environments.
Low-Speed, High-Torque Hydraulic Motor
The pump is driven by a low-speed, high-torque hydraulic motor that delivers consistent power without the high rotational speeds typical of electric motors. Lower operating speeds reduce internal wear on the impeller and volute, extend seal life, and minimize vibration. The result is a Heavy Duty Hydraulic Pump for Sand Slurry that runs quieter, cooler, and longer than comparable electric-driven alternatives.

Critical Application #1: Sand and Gravel Mining Operations
In sand and gravel mining, the ability to extract material efficiently and economically determines project profitability. Traditional methods involving draglines, clamshell buckets, or land-based excavators are often slow, labor-intensive, and limited by water depth. The Hydroman® 150THY15 Hydraulic Submersible Sand Pump solves these challenges by performing continuous, high-volume extraction directly from underwater deposits.
When mounted on a long-reach excavator positioned along the bank of a river or lake, the pump is lowered into the water until it rests on the sand bed. The hydraulic agitator immediately begins loosening and lifting the settled sand, creating a dense slurry that is drawn into the pump intake and discharged through a floating pipeline to a dewatering or processing area on shore. One operator in a single excavator can achieve production rates that would previously have required multiple pieces of equipment and a larger crew.
The Hydraulic Suction Pump for Underwater Sand excels in remote mining locations where electrical infrastructure is unavailable. The excavator's diesel engine provides all the power needed, and the pump can be relocated instantly simply by moving the machine. For marine sand mining applications, the pump's corrosion-resistant construction ensures reliable operation in saltwater environments without accelerated deterioration.
Mining operations also benefit from the pump's ability to handle oversize material. Gravel and small rocks up to 5 inches in diameter pass through the pump without causing damage or requiring manual removal. This capability reduces the need for pre-screening and allows for direct processing of run-of-mine material.
Critical Application #2: Harbor and Canal Dredging
Port authorities and marine construction firms face constant pressure to maintain navigable depths in harbors, shipping channels, and canals. Siltation reduces draft clearance, delays vessel traffic, and imposes significant economic penalties. The Excavator Hydraulic Sand Pump for Dredging offers a highly mobile, cost-effective alternative to large, specialized dredging vessels that are expensive to mobilize and unsuitable for tight spaces.
A typical harbor maintenance scenario involves an excavator positioned on a barge, a floating platform, or directly along the quayside. The Hydroman® 100THY Hydraulic Suction Sand Pump is attached to the excavator boom and lowered into the water adjacent to piers, dock faces, or berthing pockets. The operator has precise control over the pump's position, allowing targeted removal of accumulated sediment from areas that are difficult or impossible for larger dredges to access, such as between pilings, under loading arms, and around submerged infrastructure.
The built-in agitator is particularly valuable in harbor environments where sediment has had time to consolidate. As the pump works, the agitator breaks up compacted silt and clay layers, converting them into a pumpable slurry. The 6 Inch Submersible Hydraulic Pump for Sand Removal then transfers this material through a pipeline to a disposal site or barge for transport. Because the pump operates at controlled speeds and uses low-turbidity agitation, sediment disturbance is minimized, protecting water quality and aquatic life in environmentally sensitive port areas.
For canal dredging projects with limited access, the excavator can work from the canal bank, reaching across the water to clean the channel without requiring any floating equipment. This flexibility dramatically reduces mobilization time and project costs compared to conventional dredging methods. Contractors who own excavators can add dredging capability for a fraction of the cost of purchasing a dedicated dredge, and the same pump can be used for multiple projects across different sites.
Frequently Asked Questions (FAQ)
The Hydroman® 150THY15 Hydraulic Submersible Sand Pump features a 6-inch (150mm) discharge outlet and is engineered for high-volume sand and slurry transfer. The pump achieves flow rates up to 1,200 to 1,500 cubic meters per hour, depending on the specific configuration, slurry density, and discharge head requirements. Maximum head capacity reaches approximately 25 meters, making it suitable for long-distance pipeline transport. The hydraulic motor is compatible with excavators in the 15 to 30-ton class and operates using standard auxiliary hydraulic circuits. For projects requiring smaller dimensions or compacted soil handling, the Vertical 4 inch Hydraulic Dredge Pump with Jet Ring offers an alternative with reduced footprint and added jetting capability.
The agitator is arguably the most critical feature of the Hydroman® 100THY Hydraulic Suction Sand Pump and its 150THY15 counterpart. When the pump is submerged, the hydraulic-driven agitator rotates at the base of the unit, creating a powerful stirring action that lifts settled sand, gravel, and sludge from the bottom. This continuous fluidization prevents solids from compacting around the intake and ensures that the pump receives a consistent, high-density slurry rather than intermittent, low-concentration material. Without an agitator, standard centrifugal pumps quickly lose suction as they excavate a hole in the sand and then suck mostly water. With the Hydroman agitator, the Hydraulic Suction Pump for Underwater Sand maintains high production rates by continuously drawing fresh, agitated material into the pump. The result is slurry concentrations of up to 70% solids by weight, which translates directly to higher tons-per-hour production and lower fuel and labor costs per ton moved.
Yes, the Heavy Duty Hydraulic Pump for Sand Slurry can be configured with optional attachments to handle challenging, compacted materials. For hard-packed sand and compacted sediment, side cutter attachments can be mounted directly to the pump housing. These rotating cutters mechanically break up consolidated material before it reaches the agitator and pump intake, ensuring continuous feeding even in difficult conditions. For sticky clay and heavy sludge, the Vertical 4 inch Hydraulic Dredge Pump with Jet Ring configuration adds high-pressure water jets that fluidize the material and reduce adhesion to internal surfaces. The combination of mechanical cutting and hydraulic jetting allows the Excavator Hydraulic Sand Pump for Dredging to perform in environments where conventional pumps would simply polish the surface or become clogged.
