280kW Excavator Mounted Pump Description

Hydroman^® 400THY280-6P: The Ultimate 400THY280 Hydraulic Excavator Pump with Cutting Heads for Submerged Slurry Dredging

When compact underwater materials block standard pumps, you need a solution that cuts and pumps in one motion. The Hydroman^® 400THY280 Hydraulic Excavator Pump with Cutting Heads is designed for excavator-mounted, submerged heavy-duty dredging. As a 16 Inch Submersible Hydraulic Dredge Pump for Slurry, it handles up to 70% solids by weight without clogging. This 280kW Excavator Mounted Pump for Underwater Excavation delivers enormous hydraulic power directly from your host machine. The Vertical Hydraulic Slurry Pump with Excavating Cutting Heads configuration allows precise positioning on the boom. As a Heavy Duty Submerged Pump for Thick Material Excavation, it powers through sand, gravel, tailings, and industrial sludge.

Unlike electric pumps that risk seal failure underwater, this hydraulic-driven unit runs cool and safe even when fully submerged. The cutting heads rotate at low speed but with high torque, fracturing compacted soils that ordinary dredge pumps cannot touch. Whether you are cleaning a settling pond or deepening a port channel, the Hydroman^® 400THY280-6P transforms any compatible excavator into a powerful dredging vessel.

Five Design Features That Define the 400THY280 Hydraulic Excavator Pump with Cutting Heads

High-Chrome 28% Alloy Hydraulic Casing – The volute and impeller are cast from 28% chromium white iron, achieving HRC 58-62 hardness. This resists abrasion from sharp sand grains and crushed rock, extending wear life by 3–5 times compared to standard cast iron.

Interchangeable Carbide Cutting Teeth – The excavating head uses bolt-on hardmetal teeth. When worn, you replace only the tooth – not the entire cutter ring. This cuts field maintenance costs by nearly 60% and reduces downtime.

Low-Speed, High-Torque Hydraulic Motor – Operating at 400–600 RPM, the motor produces over 6,500 Nm of torque. Low rotation speed minimizes particle impact velocity, reducing impeller wear while generating enough suction to pull 120 mm solids through the 16‑inch discharge.

GS 500 Cast Steel Mounting Frame – The pump body is reinforced with GS 500 nodular cast iron, absorbing shocks from rocks and underwater obstacles. Four oversized lifting eyes allow safe handling even in choppy water.

Direct Excavator Auxiliary Circuit Connection – No external power pack needed. The pump taps into your excavator’s own hydraulic system (flow 250–400 L/min, pressure up to 350 bar). A quick-coupling manifold lets you attach or detach within 15 minutes.

Excavator Hydraulic Pump for Deep Dredging Operations

Excavator Hydraulic Pump for Deep Dredging Operations – Port Maintenance & River Deepening

Navigational channels and harbors accumulate dense silt and compacted clay over years. Standard cutter suction dredgers are expensive to mobilize. With the Hydroman^® 400THY280-6P mounted on a long-reach excavator (20–30 m boom), you can work from the bank or a barge at depths up to 25 meters. The Excavator Hydraulic Pump for Deep Dredging Operations cuts through consolidated sediments while pumping the slurry directly to a disposal site or dewatering bag. One project in Southeast Asia used this pump to remove 1,200 m³ of hard-packed river delta material per shift – work that previously required a much larger dredge.

Industrial Hydraulic Dredge Pump for Submerged Slurry

Industrial Hydraulic Dredge Pump for Submerged Slurry – Mine Tailings Reclamation & Thickener Cleanout

Tailings storage facilities accumulate dense, abrasive slurry that settles into a concrete-like layer. Electric submersibles fail due to seal abrasion. The Industrial Hydraulic Dredge Pump for Submerged Slurry sits directly on the tailings bed, its cutting heads breaking up the deposited solids while the impeller re-suspends and pumps them to a reprocessing or dry-stack filter. In a copper mine application, this pump recovered 85% of trapped metal values from a 10‑year‑old tailings pond. Similarly, for thickener underflow with 65–70% solids, the pump prevents “rat holing” and maintains steady production.

Frequently Asked Questions (FAQ)

Q1: Can the 16 Inch Submersible Hydraulic Dredge Pump for Slurry run dry for short periods?
No hydraulic pump should run completely dry for more than a few seconds. However, the Hydroman^® 400THY280-6P is designed with a large water-jacket cooling chamber and tungsten carbide mechanical seal that tolerates momentary air ingestion (e.g., when the cutting head rises above the slurry surface). Always ensure the pump inlet remains submerged during continuous operation.

Q2: What excavator size is required to power this 280kW Excavator Mounted Pump for Underwater Excavation?
The pump requires an excavator with auxiliary hydraulic flow of at least 250 L/min and operating pressure of 300–350 bar. This typically corresponds to 30–45 ton class machines (e.g., Caterpillar 336, Komatsu PC360, Hitachi ZX350). For smaller carriers, Hydroman^® offers flow-reducing valve kits.

Q3: How does the Vertical Hydraulic Slurry Pump with Excavating Cutting Heads differ from a standard hydraulic agitator pump?
Standard agitator pumps use rotating jets to stir loose sediment. Our vertical pump combines a bottom-mounted excavating cutter head (with replaceable carbide teeth) that physically breaks compacted layers – clay, cemented sand, gypsum scale – before slurry enters the intake. This allows you to excavate material that would otherwise require a separate ripper or breaker attachment.

Q4: What is the maximum pumping distance for this Heavy Duty Submerged Pump for Thick Material Excavation?
With a 280 kW hydraulic motor and 16‑inch discharge, the pump can push slurry with 40–50% solids over 800 meters horizontally (using DN400 pipeline) or lift 30 meters vertically. For longer distances, you can stage a booster pump. The actual distance depends on solids specific gravity and pipe friction – contact Hydroman^® for a customized calculation.
