Mud Cat 40E

Remote Controlled Electric Auger Dredge

The Mud Cat 40 Electric auger dredge is remote controlled and is the most popular E-Series dredge used for medium flow projects that are pumping into filter presses, geo-tubes, and centrifuges. Like the 20E, the 40E is easy to transport and fits in a 40 ft. ocean container.

The E-Series auger dredge comes in five standard models and can be customized for specific applications. The system can also be equipped with a PLC (programmable logic controller) to provide automation at industrial or wastewater facilities.  The E-Series dredge is constructed of the highest-grade materials and will outlast the competition.

Mud Cat Electric Dredges

For over 30 years, Mud Cat has been the global leader for remote-controlled electric auger dredges. Mud Cat E-Series (electric) dredges have been the preferred system by consulting engineers around the globe for removing accumulated solids from storage basins and lagoons.

All Mud Cat remote controlled electric auger dredges are manufactured at EDT’s ISO 9001:2015 Certified Factory in New Richmond, WI using the highest-grade components and steel sourced from North American mills.

Features & Benefits

Cast Iron Pump: Volute and impeller have a longer lifespan than fabricated steel pumps.

Larger Sphere Passage: Less clogging than fabricated steel pumps on competitors’ dredges.

Electric Submersible Pump: Requires less maintenance on seals and bearings than pumps powered by long drive shafts.

4-Wheel Liner Protection System: Uses 4 wheels instead of 2, drastically reducing the chance of costly poly lagoon liner damage. The pump will never hit or drag onliner like hanging pump units.

Heavy Duty 10 Gauge Steel Hull: Insures long lifespan, durability, and will not crack like plastic/poly floats, which have inherent issues with UV exposure.

Hydraulic Driven Traverse System: It provides full torque and power at all speeds.

Ladder Mounted Cutterhead: Creates even bottom profile instead of dragging through the material or creating a swiss cheese effect that calls for re-dredging.

Faster Cutting Speed: The System moves at double the speed of other auger remote controlled dredges increasing productivity.

Radio Remote Sense: A Hand-held transmitter may be operated up to over 1,000 ft. away. Operating functions indicated by dredge mounted 5-color light tree.

Automated Remote Control Dredging: Mud Cat is the world leader for dredge automation and can integrate a series of functions into a NEMA 4 or 4x control panel.

4-Moving Parts: Fewer parts equals ease of operation, reduced cost, and less maintenance.

Customization: Available with stainless hull and components, various coatings, low profile design for low bridges, slurry pump options. Special requests are welcome.

1 This represents total flow capabilities of the pump – water and solids.

2 This represents theoretical maximum solids production.  This is calculated based on 25% solids by volume and 1 complete hour cutting and pumping material.  This estimate does not take into account material properties, time used for positioning, pumping distance or elevation. Buyer should consult Mud Cat for production estimates based specifically around their application.
