A Slurry Pump Manufacturer That Builds the Whole System
EDDY Pump is a US slurry pump manufacturer and dredging equipment manufacturer based in El Cajon, California. Unlike pump suppliers that resell third-party components, we design, machine, and test everything in-house; the pump casing, the rotor, and the complete slurry pumping system around it.
That matters when your job is moving abrasive solids: mine tailings, dredged sediment, frac sand, paper pulp, or wastewater sludge. Our patented design has a very little critical-tolerance impeller to clog or wear out, which means longer intervals between maintenance, more uptime, and lower lifecycle costs than centrifugal slurry pumps.
Explore our industrial slurry pumps for sale, or send us your duty conditions, and our engineers will match the pump to the job.

What Is a Slurry Pump and How Does It Work?
A slurry pump is an industrial pump built to move liquids loaded with solids, sand, gravel, tailings, sludge, or sediment, that would destroy a standard water pump. Slurry pumps use harder materials, wider passages, and more torque to survive abrasive solids pumping.
Most slurry pumps are centrifugal: an impeller slings the mixture outward to create flow. EDDY pumps work differently. Our patented rotor generates a synchronized eddy current, like a controlled tornado, that moves the material without fine-tolerance parts. That is how an EDDY pump tolerates objects up to 11 inches in diameter and slurries of up to 70% solids by weight that clog centrifugal designs.
Choosing between a submersible, flooded suction, or self-priming configuration depends on your sump, suction conditions, and material. See our pump selection guide or request a custom pump curve, and our engineers will size the pump for your duty point.

Frequently Asked Questions
What is a slurry pump?
A slurry pump is an industrial pump designed to move liquid mixed with solids — sand, sludge, tailings, or sediment. Unlike water pumps, slurry pumps use wear-resistant materials and high-torque designs to handle abrasive solids without clogging or rapid wear.
How does a slurry pump work?
Most slurry pumps use a spinning impeller to push the mixture outward and create flow. EDDY pumps instead use a patented rotor that creates a synchronized eddy current, moving high-solids material without the tight tolerances that cause conventional pumps to clog and wear.
What makes EDDY Pump different from other slurry pump manufacturers?
EDDY Pump builds both the pumps and the dredging equipment they power, all in the USA. The patented non-clog design moves up to 70% solids by weight and passes objects up to 11 inches — performance most centrifugal slurry pumps cannot match.
What is the difference between a slurry pump and a dredge pump?
A dredge pump is a slurry pump applied to excavation: it sits at or in the material, pulls sediment from a waterway or pond, and transports it through a pipeline. EDDY dredge pumps mount on excavators, cables, or remote-operated dredges.
Can EDDY pumps handle high-viscosity or high-specific-gravity material?
Yes. EDDY pumps are engineered for high viscosity, high specific gravity, high abrasives, and low pH material — including paste-like mine tailings and bitumen — that stall vortex and positive displacement pumps.
Do you supply replacement parts and service?
Yes. As the OEM, EDDY Pump supplies slurry pump replacement parts, field service, and repair from our US factory, plus startup support and technical assistance for the life of the equipment.
Can I rent dredging equipment instead of buying?
Yes. EDDY Pump offers dredge equipment rentals for projects where purchase is not practical, including excavator pump attachments and complete dredging systems, with engineering support included.
How do I get a pump curve or quote?
Send us your flow rate, head, and material specifications through our custom pump curve form. Our engineers will produce the curve and a quotation matched to your duty point — usually within a few business days.
