Hydraulic Sand Pump Description
Heavy Duty Hydraulic Pumps for Sand Slurry Transfer don't come more robust than the Hydroman® 200THY160-6P. As a premier Industrial Submersible Sand Pump for Sediment Removal, this 8-inch unit is powered by a 160kW hydraulic drive, making it ideal for operations where electricity is unavailable. The Vertical Hydraulic Sand Pump with Bottom Agitator excels at breaking up compacted sand, while its Hydraulic Submersible Sand Pumps with Agitator System ensures continuous flow of high-density slurries. Built as a true 200mm Discharge Sand Pump for Submerged Operations, it handles up to 70% solids by weight, making it a top choice for demanding dredging and mining projects worldwide.
The 200THY160-6P stands apart from conventional electric submersible pumps because it is driven directly by a hydraulic motor. This design allows it to be mounted directly onto the arm of a hydraulic excavator, tapping into the machine’s existing power system. For remote locations without a stable power grid, this pump provides a self-sufficient, high-torque solution that electric pumps simply cannot match.
Design Features: Built for the Toughest Conditions
The Hydroman® 200THY160-6P is engineered from the ground up to handle extreme abrasion and high concentrations of solid materials. Every component is designed to maximize uptime and minimize maintenance costs in harsh underwater environments.
High-Chrome Agitator System: The pump is equipped with a heavy-duty agitator mounted at the lower part of the unit. This component rotates to fluidize settled sediments—sludge, sand, silt, and gravel—before they enter the suction inlet. By creating a localized turbidity cloud, the agitator ensures a consistently high concentration of solids enters the pump, dramatically improving efficiency over standard slurry pumps that rely solely on suction.
Dual-Action Hydraulic Drive: Unlike electric pumps that require specialized generators or grid connections, this pump is powered by a hydraulic motor that can be driven directly by an excavator’s hydraulic system or a standalone hydraulic power pack. This hydraulic drive delivers high torque even at low rotational speeds, preventing clogging and allowing the pump to handle large particles and viscous sludges without stalling.
High-Chrome Alloy Construction: All wetted parts—including the pump casing, impeller, wear plates, and agitator—are cast from high-chrome alloy. This material is specifically selected for its exceptional resistance to abrasive wear from sand, gravel, and slag. The result is a pump that lasts significantly longer than standard cast-iron units when exposed to continuous abrasive pumping.
Advanced Double Mechanical Seal: To prevent abrasive material from infiltrating and damaging the hydraulic motor, the 200THY160-6P incorporates a double mechanical sealing system. An independent oil chamber lubricates the seal faces and provides pressure balance, while optional sensors can detect moisture ingress and provide early warning before major failure occurs.
200mm (8-Inch) Discharge Port: The 200mm discharge diameter allows for high-volume transfer of sand slurry with minimal flow restriction. This oversize outlet is critical for maintaining production rates when pumping dense mixtures containing gravel or large particulate matter.
Fully Submersible Vertical Design: Designed for vertical underwater use, the pump can operate at depths up to 80 meters. Its compact, streamlined form factor allows it to be lowered directly into sumps, rivers, or seabeds without requiring complex suction piping or priming procedures.

Sand & Gravel Mining
How does the Hydroman® 200THY160-6P maximize sand extraction efficiency?
In sand and gravel mining operations, the primary challenge is extracting material from underwater deposits while minimizing water content. The Hydroman® 200THY160-6P directly addresses this by using its bottom agitator to break up compacted sand beds before pumping. The result is a slurry with up to 70% solid concentration by weight—meaning every gallon pumped contains more valuable sand and less water.
This significantly reduces dewatering costs and transportation volumes. The pump attaches directly to an excavator's boom, allowing the operator to position the suction inlet precisely over high-grade deposits and move systematically across the extraction zone without repositioning heavy equipment.
Harbor & Waterway Dredging
Can this pump handle the demands of municipal and port dredging projects?
Maintaining navigable waterways requires removing accumulated silt, sludge, and debris without disrupting port operations. The Hydroman® 200THY160-6P excels in these environments because its hydraulic drive eliminates electrical hazards underwater. The pump can be deployed from a barge or directly from the shoreline, and its high-chrome construction withstands the abrasive action of sand, shell fragments, and gravel commonly found in harbor sediments.
The agitator system prevents the pump from burying itself in soft mud, ensuring continuous operation even in unstable bottom conditions. For ports and municipalities looking to extend dredging intervals and reduce contractor costs, this pump offers a reliable, high-volume solution.
Frequently Asked Questions (FAQ)
Q1: What is the maximum solid concentration the 8 Inch Hydraulic Sand Pumps for Underwater Excavation can handle?
The 200THY160-6P can handle up to 70% solids by weight. This high concentration capability is achieved through the synergy of its powerful suction and the bottom agitator, which continuously fluidizes settled materials before they enter the pump.
Q2: How do 160kW Hydraulic Submerged Pumps for Sand Dredging compare to electric pumps in remote locations?
Hydraulic pumps like the 200THY160-6P are vastly superior in remote areas because they eliminate the need for electrical power. They can be powered directly by an excavator's hydraulic system or a diesel-driven hydraulic power pack. This makes them ideal for mining exploration sites, offshore barges, and construction zones without grid access.
Q3: What maintenance is required for the agitator system on this Vertical Hydraulic Sand Pump with Bottom Agitator ?
The high-chrome agitator is designed for extended service intervals. Under normal operating conditions, annual inspection of the agitator wear components is recommended. In continuous 24/7 operations with highly abrasive materials like quartz sand, quarterly inspections of the agitator blades and wear plates are advised to prevent unexpected downtime.
