The Marlin Class Mining Dredge is designed to meet the needs of deep mining deposits as an efficient tool to excavate materials. The Marlin can dredge depths exceeding 100 feet. This deep digging depth is made possible by the use of an underwater pump system with a high-torque cutter drive assembly. For more information, please consult DSC's Marlin page.
The Shark Class Conventional Dredge combines a conventional dredge-operating configuration with modular design for ease of transportation. The Shark is often used by sand and gravel producers and contractors. Standard discharge sizes range from 10 inches through 24 inches. For more information, please consult DSC's Shark page.
The Barracuda Class Swinging Ladder Dredge is a hull pump swinging ladder dredge with standard discharge sizes ranging from 10 inches through 16 inches. Barracuda dredges have been most commonly used in waterway maintenance and lake revitalization projects. For more information, please consult DSC's?Barracuda?page.

The Badger Class Conventional Dredge is offered in an 8-inch configuration. With a maximum digging depth of 20 feet, this 54-foot-long dredge is ideal for smaller dredging jobs where more compact equipment is required due to work area limitations. For more information, please consult DSC’s Badger page.
The Wolverine Class Conventional Dredge is 68 feet in length and is offered in a 10-inch discharge configuration. The Wolverine can dig down to 25 feet below the surface and allows for a maximum particle clearance of 6 inches. This tough, portable dredge is perfect for the light contractor and is fully functional by one person. For more information, please consult DSC’s Wolverine page.
This is the lowest possible velocity at which the dredged material will stay in suspension and move through the pipeline in a heterogeneous mixture. Below this velocity, the material begins to separate and fall out in the pipeline. The critical line velocity changes with dredging conditions and the type of material being pumped. If the operator continues to pump below this point, the pipeline will plug with material and the dredge will stop working.
Torque tubes require less horsepower because they use antifriction bearings, as opposed to the cutlass bearings, which are basically rubber sleeve-type bearings or “friction bearings.” Cutlass bearings must be flushed with clean water, which not only requires horsepower to drive the water pump, but also may be impossible to obtain in some dredging environments.
