U.S Army Engineer Research and Development Center (ERDC) and 
The Army Corps Review The Subdredge AKA The MRSD

ERDC talks about the EDDY Pump Subdredge, their dredging uses and future plans. The Army Corps call their tan colored version The Mini-Robotic Submersible Dredge or MRSD. They highlight some of the research done in conjunction with EDDY Pump and talk about the deployment options of the subdredge. EDDY Pump sells a commercial version of this unit and is the OEM.

The Subdredge will be important in Logistics Over-the-Shore (LOTS) operations. Navy and Army conduct LOTS operations and will be end users for these projects.


EDDY Pump Subdredge, as seen on the Discovery Channel and used by the Army Corps of Engineers. This state of the art subsea dredging system is unique to the market and is changing how companies dredge waterways, mine gold and perform sediment removal. Also ideal for large settling tank cleanout, pond desludging and pumping dangerous sludge or materials. Improve your safety profile in dangerous situations.

The Army Corps have adapted the Subdredge for use under the name Mini Robotic Submersible Dredge or MRS-D, of which EDDY Pump is the OEM source. 

All equipment is Powered by EDDY Pump dredge pumps, which are also available for slurry transport dredge projects. See the pump page for specific information.

Agitation Options: A Cutterhead OR high power water jetting ring is available, depending on the dredge application.

The Subdredge is a remote operated submersible dredge (ROV) that can be powered hydraulically or electrically with pump sizes ranging from 4-inch up to 10-inch with production rates of up to 4500 GPM or 400 cubic yards of material per hour.  The Subdredge is equipped with an umbilical that allows for it to operate remotely at distances of up to 1000-ft or greater from the operator. With smart technology, the system can be operated or serviced remotely from anywhere on the planet.

The Subdredge is ideal for dredging applications that call for great depths, precision dredging, unmanned operation, and liner dredging to name a few.  This dredge costs a fraction of the cost of conventional dredges and can handle a larger variety of dredging applications. Increasing your ROI by design and increasing safety by removing humans from harmful situations.


The EDDY Pump Subdredge was Featured on Bering Sea Gold. Cutterhead or Water Jetting Ring Options for Agitation. Call for details. 

Sub Dredge - Remote Operated Submersible Vehicle seen on Bering Sea Gold

All EDDY dredges use our industrial pumps, which are non-clog pumps designed for high solids pumping applications. Our patented pump technology outperforms all centrifugal, vortex and positive displacement pumps in a variety of the most difficult pumping applications.

EDDY Pump submersible gold dredge was “Alaska tested”, on the Discovery Channel show Bering Sea Gold, see More.

The core of this technology is the patented EDDY Pump technology that redefines the pumping industry, by being the only pump that utilizes the principles of a tornado to create a synchronized eddy current. This pump is not a centrifugal, positive displacement, or vortex pump, but instead the most highly efficient high solids and high specific gravity pump on the market. This translates to the ability to pump higher percent solids of material and capture the heavy specific gravity gold. With references from Bering Sea Gold, referring to it as the Golden Sea Horse Dredge, there are truly no limits for this Subdredge.

Another EDDY Pump alternative to the Subdredge is the 5-cable floating autonomous dredge. Also unmanned and remote-operated, see Autonomous Dredge HERE.

All EDDY Pump dredges use our patented USA Built industrial pumps. Since 1984

After 4-weeks of operation under the 5-foot thick ice of Nome, Alaska, the Subdredge can truly be seen as the new wave of the future in underwater gold mining and will soon be seen by millions on the Discovery Channel!
