Self-Priming Pump – 6 Inch 118/125-HP
The 6-Inch DSP/HD 6000 Self-Priming Slurry Pump is a rugged, high-capacity workhorse engineered for the heavy-duty pumping of abrasive, high-solids slurries. Driven by a Tier III John Deere 118–125 HP diesel engine, it delivers 450–2,000 GPM at up to 200 ft head. Featuring an 8″ suction, 6″ discharge, and the ability to pass solids up to 5″, this trailer‑mounted unit eliminates clogs and downtime. Built with heavy-duty components—high-chrome, stainless rotor and volute, chromemoly shaft, dual mechanical seals—it’s designed for mining, dredging, wastewater, slurry, and abrasive industrial fluids

6-inch self-priming slurry pump in
real world applications
How the Pump Works
The key differentiator of this system lies in its patented vacuum-assisted self-priming chamber. On startup, the chamber uses vacuum pressure to evacuate air from the suction hose, drawing fluid into the pump body without manual priming or flooding. Once primed, the pump operates continuously, pushing fluid through the discharge line even in fluctuating conditions. This design eliminates the need for foot valves or complex priming systems, significantly reducing operator workload and risk of failure.
Built for Real-World Use
Here’s what makes it user-friendly:
Starts Automatically
No need to pour water into the pump before use. Just start the engine, and it handles the rest.
Moves Big Debris
Can handle rocks, sand, and sludge, up to 5 inches in size, without getting jammed.
Runs All Day
With a large fuel tank, it can run for 12 to 16 hours straight without needing a refill.
Easy to Tow
Mounted on a rugged trailer, it’s ready to hitch to a truck and move to any job site.
Made for Harsh Jobs
Built strong to perform in construction, mining, dredging, and stormwater projects.

Case Study
Challenge
A busy marine terminal faced a recurring bottleneck during barge offloading operations. The facility received dredged slurry (40–60% solids) by barge, which then had to be pumped to a temporary containment zone located over 300 feet away. Traditional pumps struggled with priming issues and inconsistent performance during tidal fluctuations. The lack of access to constant vacuum assistance also limited equipment choices.
Solution
To overcome these challenges, the terminal deployed the EDDY Pump 6-Inch Self-Priming Pump (125 HP), configured for skid mounting. Key advantages included:
- Self-priming and re-priming capabilities without external vacuum support
- Ability to handle high solids content (up to 3-inch solids) without clogging
- Efficient pumping through long discharge distances using standard 6″ slurry hose
- Low-maintenance, non-clogging rotor design ideal for barge-mounted or dockside setups
The unit was placed dockside and operated continuously during the loading windows, with minimal setup time required.
Result
The installation delivered immediate and measurable benefits:
- Transferred slurry at rates exceeding 100 cubic yards per hour
- Maintained reliable performance across changing tidal conditions
- Reduced barge unloading time by 30%, boosting daily throughput
- Operated with zero priming failures, eliminating delays caused by air-lock or pump resets

Can I use this pump in saltwater or corrosive fluids?
Yes. Optional stainless steel and duplex construction is available for corrosive environments.
How long can the self-priming pump operate without refueling?
The 96-gallon fuel tank enables extended operation, typically lasting 12–16 hours, depending on the load.
