EDDY Pump industrial sludge pumps are non-clogging pumps designed for efficiently pumping industrial sludge and related applications. Our patented pump technology outperforms all centrifugal, vortex and positive displacement pumps in a variety of the most difficult pumping applications.

Main Applications:  Mining, Dredging, Wastewater, Chemical, Paste, Oil, Sludge, Sand, Mud, Paper/Pulp, and more.


The EDDY Pump’s adjustable size and ultra recessed rotor can pass the largest material in the industry.

In harsh conditions with sand, sludge, rocks, and sludge, normal dredge pumps clog, wear and fail more often. This leads to downtime for maintenance, hurting your bottom line. This is not the case with EDDY Pumps, since we have the tolerance to pump solid objects up to 9 inches without damaging the pump!

We Pump Solids
Not Water

Pass solids from 1-9 inches (rocks, rags, debris). The EDDY Pump’s open rotor design with high tolerances allow anything that will go into the pump’s intake to be passed through the discharge without issues.

The tolerance between the rotor and the volute in the 4″ EDDY Pump easily allows the passage of a man’s arm (*see picture below). Compared with the tolerance in a centrifugal pump, the EDDY Pump easily wins. Over the span of our 2-inch through 10-inch EDDY Pump line, the tolerance ranges from 1-9 inches.

This translates to a significant amount of solids and debris pass through, without clogging the pump. To learn more about the technology behind our pumps continue reading Here.

Pump Line & Spec Sheets

The Commercial and HD EDDY Pumps power our process pumps, dredge equipment and excavator attachments.

Pump Deployment Options

Flooded Suction Pumps

With flooded suction pumps, the sludge to be pumped is positioned above the pump. With the pump positioned below, gravity can feed the sludge or fluid into the suction of the pump which keeps the pump primed.

Submersible Pumps

Pumps that are completely submerged in the liquid are called submersible pumps. By being submerged in the fluid to be pumped, there is no need for priming.

Self-Priming Pumps

With a self-priming unit, the pump and power unit are not submerged. The suction house goes into the slurry and the unit acts like a super-sized wet dry vacuum. Can be trailer mounted for added mobility.
