How the Pump Works
The 4-Inch DSP/HD 4000 self-priming pump features EDDY Pump’s patented open rotor design, which generates a powerful eddy current inside the volute. This vortex motion allows the pump to move high-viscosity fluids and slurries with minimal restriction, even those containing solids up to 3 inches in diameter.
Its key advantage lies in the vacuum-assisted self-priming system. At startup, the vacuum chamber evacuates air from the suction line, enabling the pump to draw fluid without the need for manual priming or foot valves. Once primed, the system maintains a consistent flow—even through fluctuating suction conditions—eliminating the need for complex priming hardware and minimizing operator intervention.
Vacuum-Assisted Startup
Built for Real-World Use
The DSP pump 4000 series is designed for reliable performance in the harshest environments—from construction and mining sites to flood remediation and slurry transfer operations.
Here’s why it stands out:
- Automatic Priming: A vacuum-assisted chamber eliminates the need for manual priming. Simply start the engine, and the pump takes care of the rest.
- Solids-Handling Power: Moves sludge, gravel, sand, and debris up to 3 inches with minimal wear or clogging.
- Extended Runtime: A 96-gallon fuel tank delivers up to 12–16 hours of operation on a full load, reducing refueling downtime.
- Towable & Portable: Trailer-mounted with DOT lighting, heavy-duty hitch, and integrated lifting bail for easy site relocation.
- Built to Last: Corrosion-resistant metallurgy and no-close-tolerance design mean fewer breakdowns and longer service intervals.

Case Study Portable Slurry Pumping at Frac Site
Challenge
A fluid services contractor needed a rugged, portable pumping solution to clean out multiple frac tanks at a remote well pad. The tanks contained abrasive drilling mud and bentonite-barite slurry with high solids content. Previous pump setups required frequent maintenance and failed to run continuously in demanding field conditions.
Solution
The contractor deployed the 4-Inch DSP/HD 4000 self-priming pump, mounted on a DOT-rated single-axle trailer. Its high chrome rotor and volute withstood the abrasive slurry, while the vacuum-assisted self-priming system eliminated the need for external priming tools. With a 96-gallon fuel tank and 12–14 hours of runtime, the unit was perfectly suited for remote, off-grid operations.
Result
- Completed 10 frac tank cleanouts in just 3 days
- Zero clogging or downtime, even with high-viscosity slurry
- Fuel-efficient performance reduces on-site refueling needs
- Operators praised its ease of transport and setup, reducing manpower needs by 25%
- Extended equipment life due to abrasion-resistant materials and a sealed flush system
