Industries Served

Dredging

Ideal for removing sediment, sand, and silt from rivers, ponds, and canals. The pump’s 70% solids handling and 3-inch solids passage make it reliable for small to mid-scale dredging projects.

Mining

Built for abrasive slurries and tailings, the pump’s high-chrome and stainless steel construction resists wear, ensuring longer run times in demanding mineral processing and excavation environments.

Construction

Efficiently manages dewatering and slurry transfer on construction sites. Its trailer-mounted design and self-priming system provide fast setup and mobility across multiple projects.

Case Study

The Challenge

A municipal wastewater treatment facility struggled with transferring thick sludge from settling basins to digesters. The sludge contained high levels of grit and organic debris, which frequently clogged their existing centrifugal pumps. Frequent breakdowns caused delays in operations, increased maintenance costs, and forced operators to clear blockages manually.

The Solution

The facility deployed the EDDY Pump’s 3-inch 43-HP Self-Priming Pump, mounted on its trailer for easy mobility around the site. With the ability to pass 3-inch solids and handle up to 70% solids by volume, the high-performance self-priming pump proved capable of managing the heavy sludge flow without clogging. Its dual mechanical seal and self-flushing system further protected against wear and in abrasive conditions.

The Result

The sludge transfer process became significantly more reliable, resulting in reduced downtime across the plant. Operators reported a 50% reduction in manual unclogging efforts, while maintenance costs dropped due to extended pump component life. The municipality was able to maintain smooth operations, improve efficiency, and reduce overall operating expenses.

Frequently Asked Questions

What makes the EDDY Pump different from standard centrifugal pumps?

Unlike centrifugal pumps, the EDDY Pump uses a patented rotor design that creates a high-velocity vortex. This allows it to move slurry with up to 70% solids by volume while minimizing clogging, wear, and downtime.

What is the maximum particle size the 3-Inch Self-Priming Pump can handle?

This model can pass solids up to 3 inches in diameter, making it ideal for applications with debris, rocks, rags, or other large particulates that often clog traditional pumps.

Does the 43 hp self-priming pump require priming before operation?

No. The self-priming design eliminates the need for external priming systems or foot valves, reducing setup time and simplifying operation in remote or changing site conditions.

What type of engine powers this 3-inch 43 hp self-priming pump?

It is powered by a 43-HP Kubota V2403-MDI turbocharged diesel engine, liquid-cooled, and backed by a 2-year/2,000-hour warranty, ensuring reliable service in tough environments.

Can the pump be easily moved between job sites?

Yes. The industrial self-priming pump comes trailer-mounted with a 6k single axle, integrated lifting bail, leveling jacks, and a 96-gallon fuel tank. This allows fast mobilization for dredging, dewatering, or sludge handling projects.

How does the DSP/HD 3000 pump perform with abrasive slurries?

The 3-inch 43 hp self-priming pump is built with high-chrome, stainless steel, and duplex stainless steel wear parts. These materials, combined with a recessed rotor design, give it excellent resistance to abrasion and extend component life.

What maintenance does the mechanical seal require?

The 43 hp self-priming pump is equipped with a dual mechanical seal system made of tungsten or silicon carbide. It includes a self-contained flushing system that keeps the seal lubricated and cool, significantly reducing failure rates and maintenance intervals.

Is the heavy-duty self-priming pump suitable for corrosive or chemical environments?

Yes. Custom metallurgy options such as duplex stainless steel are available for the rotor and volute casing, making the pump suitable for corrosive slurries or wastewater containing aggressive chemicals.

What is the flow and head capacity of this pump?

The 3-inch 43 hp self-priming pump delivers 100–780 GPM with a maximum head of 130 ft. This performance range makes it versatile for use in dredging, mining, construction, wastewater treatment, and industrial applications.

Can I request additional accessories with the DSP/HD 3000 pump?

Yes, we offer a flexible accessory package to match your operational needs. While the standard kit includes a work light, flow gauge, and tie-downs, we can equip your pump with additional solutions, such as discharge hoses, extended fuel tanks for longer runtimes, and custom trailer setups for site-specific transport or deployment. Just let us know your application requirements, and we’ll configure the package accordingly.
