Moray Class - Submerged Pump Swinging Ladder Dredge

At DSC Dredge, we know designing and building the exact custom dredge that will boost your efficiency and lower your costs involves working with you and learning your story. The productive and portable Moray Class offers a swinging ladder configuration with the conventional closed-loop underwater dredge design. Starting with our base model, we customize the Moray for your specific application, learning all details of your project, and involving you every step of the way.

With its hydraulically driven underwater pump assembly, the Moray Class swinging ladder dredge is ideally matched to the current dredging industry trend of pumping low flow rates with higher-percent solids—including applications such as pumping into geotubes or retention areas that do not accommodate large volumes of water. It is available with an 8-inch (200 mm) discharge configuration and offers single-truck portability in most areas of the world. Custom features, sizes, and designs are available.
