16 Inch Excavator Mounted Pump Description
Have you ever tried to shift heavy sludge with a standard pump, only to watch it clog up with abrasive grit, sand, and gravel? The Industrial Hydraulic Sludge Pump for Deep Cleaning, specifically the Hydroman® 400THY315-6P, solves this by turning a standard 20-tonne excavator into a high-efficiency dredging powerhouse. This Submersible Hydraulic Pump for 20 Tonne Excavator runs directly off the machine’s hydraulic circuit—no electric cables required. It is built as a Vertical Hydraulic Sludge Pump for Underwater Operation, capable of moving extreme concentrations of solids with ease. When you need a Heavy Duty Excavator Pump for Thick Sludge Handling, this model stands as the industry standard for reliability and raw power.
Efficiency on a dredging site is not just about flow; it is about moving dense, heavy material without burning through wear parts. The Hydroman® 400THY315 Hydraulic Submersible Sludge Pump (16 inch, 315kW) is designed for vertical underwater operation on 20 tonne excavators. Ideal for efficient sludge removal. Contact us today! This unit utilizes a massive 315kW hydraulic motor that generates high torque at relatively low rotational speeds—a critical factor in extending service life. Unlike electric motors that risk burnout when overloaded, this hydraulic drive automatically adjusts to load variations, ensuring continuous operation even when pumping slurries with up to 70% solids by weight.
Design Features of the 16 Inch Excavator Mounted Sludge Pump for Cleaning
When handling thick sludge, sand, or tailings, the internal construction of the pump determines its lifespan. The Hydroman® 400THY315-6P is engineered specifically for the high flow and pressure output of excavators in the 20–30 tonne range. Here are six critical design features:
High-Efficiency Agitator System: A powerful bottom agitator continuously lifts settled solids from the bottom, turning compacted sand or sludge into a pumpable slurry without requiring additional high-pressure water jets.
High-Chrome Wear Parts: The wet end components are cast from high-chrome abrasion-resistant alloys (often GS 500 or equivalent), providing exceptional durability against the erosive wear caused by sand, gravel, and mining slag.
Run-Dry Capability: The hydraulic motor is cooled by the excavator’s hydraulic oil, allowing the pump to operate in fluctuating water levels or “snoring” conditions without damage—a feature impossible with standard electric submersible pumps.
Low Oil Flow & Low Rotation Speed: The pump operates at optimized RPMs to minimize internal friction and wear on the impeller and volute liner, significantly reducing maintenance intervals compared to high-speed electric pumps.
Large Solids Passage: The pump hydraulics are designed to pass solids up to 120 mm without clogging, making it suitable for gravelly slurries, coal sludge, and industrial debris.
Direct Boom Mounting: It connects directly to the excavator’s boom linkage, allowing the operator to precisely position the pump in deep pits, ponds, or trenches without requiring cranes or auxiliary lifting gear.

The versatility of the Hydroman® 400THY315-6P allows it to replace grab buckets, long-reach excavators, and stationary dredging systems in two particularly demanding environments:
Mining & Quarrying: Tailings Reclamation and Sump Cleaning
In mining operations, the accumulation of mill scale, tailings, and sand creates significant operational bottlenecks. The Hydroman® pump allows an operator to walk a 20-tonne excavator to the edge of a tailings pond and hydraulically extract material directly.
The high-chrome construction withstands the abrasiveness of iron ore slurry, coal reject, and mineral sands. By pumping these solids directly to a dewatering screen or holding pond, mines can eliminate the need for haul trucks and wheel loaders in dangerous, unstable sump areas, significantly reducing operating costs and improving site safety.
Industrial & Wastewater: Caisson Emptying and Mill Scale Removal
Steel mills, thermal power plants, and industrial wastewater treatment facilities face the constant challenge of removing heavy sludge from deep pits. The 315kW Hydraulic Submerged Pump for Sludge Removal is perfectly rated for vertical underwater operation in caissons, clarifiers, and scale pits.
Unlike fixed electric pumps that require draining the pit for repair, the excavator can simply lift the Hydroman pump out for inspection while another machine continues dredging. It handles the high specific gravity of mill scale and fly ash slurry without losing suction, restoring holding capacity to settling ponds and equalization basins rapidly.
Frequently Asked Questions (FAQ) About the Hydroman® Submersible Sludge Pump
Q1: Can I install the 400THY315 Hydraulic Submersible Sludge Pump for Excavator on any 20-tonne machine?
Yes, generally. The Submersible Hydraulic Pump for 20 Tonne Excavator is designed to utilize standard auxiliary hydraulic circuits found on most leading brands (Caterpillar, Komatsu, Hitachi, Volvo, Doosan) in the 20–30 metric tonne class. To ensure optimal performance, we verify your excavator’s hydraulic flow (L/min) and operating pressure (Bar) to match the pump’s requirements perfectly, ensuring you achieve maximum solids production without starving the motor of oil flow.
Q2: How does this pump handle thick sludge without clogging?
The unit combines low RPM with a recessed or open impeller design and a large free passage. Unlike standard dewatering pumps that rely on thin, clean water for cooling, this Heavy Duty Excavator Pump for Thick Sludge Handling uses a robust agitator to fluidize dense material right at the suction inlet. The hydraulic motor provides consistent torque even when the pump is submerged in heavy clay or sticky industrial sludge, preventing stall conditions common in electric pumps.
Why the Vertical Design Matters for Your Dredging Operation
As a Vertical Hydraulic Sludge Pump for Underwater Operation, the Hydroman® 400THY315-6P is specifically optimized for deep dredging. The vertical shaft design ensures the impeller remains fully primed, even when the excavator reaches down into uneven terrain. Because the unit mounts directly on the stick, the operator can feel the bottom composition and adjust the pump angle in real-time to maximize concentration. This eliminates the need for complex floating platforms or divers to reposition the pump. The result is a quicker, safer, and significantly more profitable dredging campaign.
Do not waste time with inefficient grab buckets or underpowered dewatering pumps. The Hydroman® 400THY315 hydraulic Submersible Sludge Pump (16 inch, 315kW) is designed for vertical underwater operation on 20 tonne excavators. Ideal for efficient sludge removal. Contact us today!
