Hydroman® 6 Inch Slurry Pump Description
When tackling extreme slurry conditions in remote or underwater environments, you need a pump that delivers both power and durability. The Hydroman 150THY22 Hydraulic Submersible Slurry Pump is engineered to handle high-density slurries with up to 70% solids by weight. As a true 6 Inch Hydraulic Dredge Pump for Slurry, it combines a 150mm discharge flange with a robust hydraulic drive system. This 150mm Discharge Excavator Hydraulic Slurry Pump mounts directly onto excavator booms or operates via standalone hydraulic power units. With 22kW of hydraulic motor power, the 22kW Hydraulic Submersible Dredging Pump Solution offers unmatched torque for agitating and pumping abrasive materials like sand, gravel, and tailings. Designed as a Vertical Hydraulic Pump for Underwater Slurry Removal, it eliminates the risks of electric pump failures in wet or deep-dredging applications. Below, we explore why this pump is the go-to choice for professionals worldwide.
Key Design Features of the 6 Inch Hydraulic Dredge Pump for Slurry
The Hydroman® 150THY22-6P stands apart due to its heavy-duty construction and field-proven components. Here are five essential design features that make it a reliable Excavator Mounted Hydraulic Slurry Dredge Pump:
High-Chrome Wear Parts – The wet end (impeller, volute liner, and agitator) is cast from high-chrome alloy (Cr27+). This material delivers exceptional resistance to erosion and abrasion, extending service life by 3–5 times compared to standard cast iron pumps when handling sharp sands or crushed ores.
Built-In Agitator with Optional Cutter Head – A hydraulically driven agitator at the suction inlet fluidizes settled solids, preventing clogging and increasing pumping efficiency. For compacted soils or clay layers, an optional tungsten-carbide cutter head can be retrofitted, turning the pump into a true dredging tool.
High-Torque Hydraulic Motor – The 22kW (30 HP) radial piston motor generates low-speed, high-torque output – ideal for thick slurries. Unlike electric motors, it tolerates temporary overloads, stall conditions, and full submersion without damage. Operating pressure ranges up to 250 bar, with flow rates adjustable via the excavator’s auxiliary circuit.
150mm (6 Inch) Discharge Flange – The large bore allows passage of solids up to 120mm in diameter. This Heavy Duty Hydraulic Pump for Slurry Dredging maintains high flow rates (up to 400 m³/h depending on head) while minimizing blockages from debris or oversize particles.
Modular Mounting Design – Equipped with a universal bracket and quick-coupler adapter, it attaches to any excavator from 8 to 25 tons. Alternatively, it can be deployed as a standalone submersible pump using a hydraulic power pack and lifting frame. The vertical orientation ensures stable operation in water depths up to 30 meters.

While this Vertical Hydraulic Pump for Underwater Slurry Removal serves many industries, two applications showcase its unmatched capability:
Mining Tailings & Sand Mining Operations
In active mines and quarries, tailings ponds accumulate fine abrasive solids that quickly destroy electric pumps. The Hydroman 150THY22 Hydraulic Submersible Slurry Pump is lowered directly into settling ponds or sumps, where its agitator suspends settled tailings while the 6-inch discharge transfers slurry to dewatering cyclones or disposal areas. Because it runs off the excavator’s own hydraulic system, no external power lines are needed – a critical advantage in remote mining sites.
Operators report consistent pumping of 50–60% solid content (by weight) for over 2,000 hours before wear part replacement. This Heavy Duty Hydraulic Pump for Slurry Dredging also handles sand extraction from riverbeds or underwater pits, achieving production rates of 150–200 tons per hour depending on particle size.
Port & Harbor Deep Dredging
Maintaining navigable depths in ports requires removing silt, clay, and debris without disrupting vessel traffic. The Excavator Mounted Hydraulic Slurry Dredge Pump attaches to a long-reach excavator on a barge or seawall. The pump’s vertical design allows dredging to depths of 20–30 meters, while the optional cutter head breaks up compacted seabed materials.
Unlike clamshell buckets that leave loose material, this pump continuously removes slurry through a floating pipeline. Port authorities favor the 22kW Hydraulic Submersible Dredging Pump Solution because it operates quietly (no electric motor hum), eliminates shock hazards, and works in saltwater without corrosion issues – the high-chrome alloy resists both abrasion and galvanic attack.
Frequently Asked Questions About the Heavy Duty Hydraulic Pump for Slurry Dredging
Q1: Can the Hydroman 150THY22-6P run on any excavator, or does it require a specific hydraulic flow?
A: The pump is compatible with excavators ranging from 8 to 25 metric tons. It requires a hydraulic auxiliary circuit delivering 80–150 L/min at 200–250 bar. Most midi and standard excavators (e.g., CAT 313–320, Komatsu PC130–200, Hitachi ZX120–210) meet this specification. For smaller carriers, flow reducers can be installed. Always consult the pump’s technical datasheet to match flow and pressure – excessive flow may overspeed the motor.
Q2: How does the built-in agitator differ from a cutter head, and when should I use each?
A: The agitator is a helical auger that rotates at the suction inlet, fluidizing loose sand, gravel, and sludge into a homogeneous slurry. Use it for tailings, dredged sediment, and mine waste. The optional cutter head replaces the agitator with hardened steel teeth that mechanically break up compacted clay, shale, or cemented tailings. Choose the cutter head when you encounter hard-packed layers or roots. Both are hydraulically driven by the same motor, but the cutter head consumes more torque – ensure your excavator’s hydraulic power is sufficient.
Q3: What maintenance does the 6 Inch Hydraulic Dredge Pump for Slurry require?
A: Daily checks: inspect the hydraulic hoses for leaks, ensure the swivel joint rotates freely, and flush the pump with clean water after pumping highly abrasive slurry. Every 200 hours: replace the hydraulic oil filter (if using a separate power unit) and check the motor’s case drain for contamination. Wear parts (impeller, liner, agitator) typically last 1,500–2,500 hours in silica sand; replace them when clearance exceeds 5mm or pumping efficiency drops. All wear components are field-replaceable with basic tools – no special alignment required.
Why the 22kW Hydraulic Submersible Dredging Pump Solution Outperforms Electric Alternatives
Electric submersible slurry pumps fail when cables are cut, seals leak, or motors overheat in deep water. The Hydroman 150THY22 Hydraulic Submersible Slurry Pump eliminates these vulnerabilities. Hydraulic power is transmitted via steel-reinforced hoses – no electrical hazards in wet environments. The motor runs cool even when fully submerged or running dry for short periods. Torque remains constant regardless of pump speed, so thick slurries are churned through the 150mm discharge without stalling. Additionally, the pump’s weight (approximately 180 kg) is easily handled by the excavator arm, allowing precise positioning. For operators who already own hydraulic excavators, the Excavator Mounted Hydraulic Slurry Dredge Pump is a cost-effective attachment – no separate power source, no cable drum, no explosion-proof certifications.
The vertical orientation further improves suction performance. While horizontal pumps require priming and risk cavitation, the Vertical Hydraulic Pump for Underwater Slurry Removal sits with its suction inlet fully submerged, leveraging hydrostatic pressure to feed dense slurries. This design also reduces footprint – ideal for working inside cofferdams, caissons, or narrow dredging trenches.
From mining tailings to harbor deepening, the Hydroman® 150THY22-6P Hydraulic Submersible Slurry Dredge Pump features 150mm (6 inch) discharge and 22kW power.
