Suction dredgers

In many variations, fitted for your needs

For decades, we have been developing and manufacturing high-performance suction dredger solutions for the extraction of sand, gravel, and other mineral raw materials. With over 400 suction dredgers delivered worldwide, we possess extensive experience in the design and implementation of customized extraction systems.

Our product portfolio includes suction dredgers, cutter-head dredgers, and bucket-wheel dredgers. We always select the optimal design based on specific deposit characteristics, geological conditions, and our customers’ individual requirements. We do not offer off-the-shelf solutions; every dredger is precisely tailored to the specific deposit and desired operating conditions.

Thanks to our high level of in-house manufacturing at our Norden facility, all suction dredgers are produced by a single source. From design and fabrication to final assembly and commissioning, every component is manufactured, assembled, and comprehensively tested in our own plant. The result is robust, durable, and high-performance equipment designed for economical and reliable operation.

For demanding transport tasks, we offer powerful submersible pumps for deep-water extraction and booster stations for long-distance transport. Our modular design enables cost-effective road transport and rapid on-site assembly—often within just one or two days.

Our proprietary dredge pumps are distinguished by high efficiency, reliability, and excellent spare parts availability. In addition, we provide service and spare parts for existing Marheine suction dredgers and Warman pump systems. Modern automation solutions, remote access via tablet or smartphone, and variable-frequency drives ensure energy-efficient and user-friendly operation. High-quality industrial coatings also guarantee long-term protection, even under demanding operating conditions.
