You’ve got a pond full of muck. A tailings pond that’s overflowing. A river channel that’s silted shut. Or maybe you’re dealing with a flooded construction site where the mud is too thick to dig and too wet to haul.
A standard excavator bucket can’t handle it. A conventional electric pump clogs or burns out. What you actually need is a sludge pump for sale that attaches directly to your excavator—turning your machine into a powerful dredging unit.
But here’s the catch: flow rate, lift height, excavator tonnage, agitator power, stirrer torque—these numbers don’t mean much if you don’t know what you’re looking at. This guide explains everything in plain language. Match the pump to your job, avoid expensive mismatches, and get real value from your dredge pump attachment for excavator.
What Is A Sludge Pump For Excavators?
It’s a hydraulic pump that mounts on your excavator arm in place of the bucket. Instead of digging and scooping, it sucks up slurry—water mixed with sand, silt, mud, gravel, or tailings—and pumps it through a discharge pipe to a disposal area.
Think of it as a powerful vacuum combined with a pump. It stirs up settled solids, pulls them into the intake, and pushes them out through a hose.
The power comes from your excavator’s hydraulic system. No external generator. No electric cables. Just your machine, running on diesel, working anywhere.
A dredge pump attachment for excavator is the solution when:
- Material is too wet or loose for a bucket
- Water depth makes conventional excavation impossible
- The job site has no access to electricity
- You need to pump slurry over long distances
- You’re working in remote areas or confined spaces
This is a specialized tool. But when the conditions are right, nothing else comes close.
What Makes A Dredge Pump Attachment For Excavator Good Vs. Great?
The Basics: Flow and Lift
Every sludge pump for sale has two key numbers:
- Flow (m³/h) — how much slurry it moves per hour
- Lift (meters) — how high or far it can push the slurry
You need both to match your job. High flow with low lift works for moving large volumes over flat terrain. Lower flow with higher lift works for pumping uphill or over longer distances.
The Hidden Factors
Agitator power. A weak agitator can’t stir up settled material. The pump runs dry, sucks air, and loses prime. More kW means better solids suspension and higher slurry concentration.
Stirrer torque. This is the twisting force applied by the stirring mechanism. Higher torque means it can break through compacted layers—hard-packed sand, settled tailings, clay. Our models range from 1556 to 2433 units of torque, matched to the excavator size.
Wear materials. Slurry is abrasive. Sand and gravel wear down pump components quickly. Quality units use high-chromium alloy for the pump shell, impeller, liner plates, and agitator. That’s the difference between a pump that lasts for years and one that fails in months.
Seal design. Slurry pumps are notorious for seal failure. Cheap units use basic seals that fail within days. Quality pumps use specialized sealing systems that keep abrasive particles out and reduce maintenance frequency.
Hydraulic motor quality. The motor is the heart of the pump. We use proven axial piston motors and radial piston motors—built for heavy-duty cycles, stable performance, and high efficiency. The specific motor displacement is matched to your excavator’s hydraulic flow.
Excavator tonnage match. This is non-negotiable:
- 10–20-ton excavators — Use smaller pump models (YG200-15, YG150-30, YG300-20)
- 20–30-ton excavators — Step up to medium models (YG400-10, YG500-15, YG250-35)
- 30–40 ton excavators — Large models (YG300-30, YG400-30, YG400-40)
Match the pump to your excavator’s hydraulic capacity. Undersized pumps run poorly. Oversized pumps strain your machine and waste fuel.
Our Sludge Pump Line: Clear Specs, Real Performance
We manufacture a full range of sludge pumps for sale with clear specifications, so you know exactly what you’re getting.
Small Excavator Series (10–20 Ton)
| Model | Flow (m³/h) | Lift (m) | Agitator Power | Stirrer Torque |
| YG200-15 | 200 | 15 | 5.5 kW | 1556 |
| YG150-30 | 150 | 30 | 5.5 kW | 1556 |
| YG300-20 | 300 | 20 | 5.5 kW | 1556 |
These are entry-level pumps for smaller excavators. Good for shallow ponds, small channels, and light slurry work.
Medium Excavator Series (20–30 Ton)
| Model | Flow (m³/h) | Lift (m) | Agitator Power | Stirrer Torque |
| YG400-10 | 400 | 10 | 7.5 kW | 1946 |
| YG500-15 | 500 | 15 | 7.5 kW | 1946 |
| YG250-35 | 250 | 35 | 7.5 kW | 1946 |
More flow, better lift, stronger agitation. These are the most popular models for general dredging work. High flow for volume, or lower flow for longer distances.
Large Excavator Series (30–40 Ton)
| Model | Flow (m³/h) | Lift (m) | Agitator Power | Stirrer Torque |
| YG300-30 | 300 | 30 | 15 kW | 2433 |
| YG400-30 | 400 | 30 | 15 kW | 2433 |
| YG400-40 | 400 | 40 | 15 kW | 2433 |
Maximum power, highest torque, greatest lift. These are for heavy-duty mining, large-scale dredging, and high-volume tailings management.
All Models Include
- High-chromium alloy wear parts for long life
- Heavy-duty agitator for solids suspension
- Side cutter option for compacted material
- Standard excavator mounting plate (compatible with most brands)
- Factory-tested before shipping

Final Takeaway
A sludge pump for sale that’s too small won’t clear your material. One that’s too large strains your excavator. The right pump matches your tonnage, your solids type, and your required flow and lift.
We build pumps that hit that mark. No over-engineering. No cheap materials. Just solid equipment from a supplier who stays with you after the sale.
Tell us your excavator tonnage, material type, and pumping distance. We’ll recommend the right model—no upsell, just the right fit.
