Hydroman 300THY185-6P Pump Description
When standard centrifugal pumps fail to handle thick, fibrous pulp mixtures, the Hydroman® 300THY185-6P steps in as a game-changing solution. This Hydraulic Submersible Pulp Mixing Pump with Excavators is engineered to submerge directly into pulp chests, mixing tanks, and effluent ponds, where it aggressively breaks down settled solids using dual side excavators. Unlike traditional electric submersible pumps, this Vertical Hydraulic Slurry Pump for Pulp Mixing draws power directly from your excavator‘s hydraulic system, eliminating electrical hazards in wet environments. As an Underwater Hydraulic Pump for Pulp and Solids Mixing, it handles up to 70% solid content by weight, far exceeding the capabilities of conventional pumps. The Submerged Hydraulic Slurry Pump with Side Excavators features high-chrome alloy wear parts that withstand the most abrasive pulp slurries, while the Heavy Duty Hydraulic Pulp Mixing Pump for Industry design ensures continuous operation in demanding mill environments. Whether you operate a paper mill, a mining tailings pond, or an industrial waste treatment facility, this Industrial Submersible Pump for Pulp Mixing Applications delivers unmatched reliability and performance. With its robust Hydraulic Vertical Slurry Pump with Dual Side Excavators, the Hydroman® 300THY185-6P transforms challenging mixing and pumping tasks into efficient, low-maintenance operations.
The Hydroman® 300THY185-6P represents a significant advancement in hydraulic submersible pump technology, specifically tailored for pulp and paper industry applications. Where conventional electric submersible pumps struggle with high-consistency pulp (typically 8–20% fiber content) and risk clogging or motor burnout, this hydraulic-driven powerhouse thrives. The pump attaches directly to your excavator‘s boom arm, leveraging the machine’s hydraulic system to drive both the main impeller and the dual side excavators. This integration means no separate power unit, no complex electrical wiring, and no vulnerability to water ingress—just pure hydraulic force converting into aggressive mixing and pumping action.
For pulp mills facing consistency challenges, the Hydroman® 300THY185-6P offers a distinct advantage. Traditional pumps often require dilution to reduce pulp consistency before pumping, adding unnecessary water that must later be removed. This Hydraulic Submersible Pulp Mixing Pump with Excavators eliminates that step by directly agitating and pumping high-density pulp without dilution, saving both water and energy costs.
Design Features
Dual Side Excavators for Aggressive Solids Breakdown
The pump is equipped with two heavy-duty side excavators (agitator cutters) that rotate independently of the main impeller. These cutters break apart compacted sludge, settled pulp fibers, sand, and other solid materials that have accumulated at the bottom of tanks or ponds. By continuously agitating the surrounding medium, they transform settled solids into a homogeneous, pumpable slurry, preventing stratification and ensuring consistent output.
High-Chrome Alloy Wear Components for Maximum Durability
All flow-passage components—including the impeller, volute casing, side cutter blades, and agitator—are precision-cast from high-chrome white iron alloy (Brinell hardness 600+). This material selection provides exceptional resistance to abrasive wear from sand, pulp fibers, lime slurries, and other erosive media, significantly extending the pump’s service life compared to standard cast iron or stainless steel pumps.
Vertical Submersible Configuration for Deep Tank Operation
The compact vertical orientation of the Hydroman® 300THY185-6P allows it to submerge fully in pulp chests, mixing tanks, or effluent sumps up to significant depths. This design eliminates the need for suction piping, complex priming systems, or external mixing devices. The pump operates directly where the material sits, drawing slurry through a wide intake that minimizes clogging risk.
Hydraulic Drive System with Variable Speed Control
Powered directly by the excavator’s hydraulic system (or a standalone hydraulic power pack), the pump offers variable speed control. Operators can adjust pump RPM on the fly to match varying slurry densities and discharge distances. The hydraulic motor contains no electrical components, making the pump intrinsically safe for submerged operation in wet or potentially hazardous environments.

High-Consistency Pulp Mixing in Paper Mill Chests
In pulp and paper manufacturing, maintaining consistent fiber distribution in mixing chests is critical for final paper quality. Settled pulp fibers create inconsistencies that lead to sheet defects, increased downtime for chest cleaning, and wasted raw material. The Hydroman® 300THY185-6P attaches to an excavator positioned above the chest, lowering the pump directly into the pulp. The dual side excavators continuously stir and agitate the fiber suspension, breaking up any settled clumps and ensuring a uniform consistency throughout the chest. This continuous mixing action allows mills to maintain higher consistency levels (up to 12–18%) without the need for dilution, reducing water usage and downstream drying energy requirements. The pump then transfers the homogenized pulp to the next processing stage, all in a single integrated operation.
Industrial Waste Sludge Handling and Effluent Management
Paper mills generate significant volumes of waste sludge—thick, fibrous, and highly abrasive material that quickly wears out standard centrifugal pumps. The Hydroman® 300THY185-6P excels in effluent treatment systems, sludge lagoons, and waste collection ponds. Its high-chrome wear parts withstand the abrasive action of lime sludge, calcium carbonate residues, and fiber-laden wastewater. The side excavators break up crusted surfaces and settled solids that form on pond bottoms, turning them into a pumpable slurry that can be transferred to dewatering equipment or disposal sites. This capability eliminates the need for manual dredging or multiple pump stages, dramatically reducing maintenance costs and system downtime.
Frequently Asked Questions (FAQ)
Yes. The Hydroman® 300THY185-6P is specifically designed for high-consistency pulp applications. The dual side excavators pre-agitate the pulp before it reaches the impeller intake, breaking apart fiber clumps and preventing clogging. The open-impeller design and wide flow channel further ensure smooth passage of fibrous materials. The pump reliably handles pulp consistencies up to 18% and, in some configurations, even higher without dilution.
Electric submersible pumps face two major limitations in paper mills: electrical hazard risks in wet environments and motor burnout from high-density slurries. The Hydroman® 300THY185-6P eliminates both issues by using hydraulic power. There are no electrical components submerged in the pulp, making it safer and more reliable. Additionally, the hydraulic motor operates at lower rotational speeds than electric motors, reducing wear on internal components and extending the pump‘s lifespan in abrasive pulp applications.
Maintenance is straightforward and minimal. The high-chrome alloy wear components should be inspected periodically for signs of abrasion wear. The double mechanical seal prevents slurry ingress into the hydraulic motor. Daily checks should include verifying hydraulic oil levels and inspecting the side excavator blades for damage. Under normal pulp mixing conditions, the pump typically requires a major service interval of 3,000 to 5,000 operating hours—significantly longer than standard centrifugal pumps.
