SDP Series – Submersible Dredge Pumps

SDP Series submersible dredge pumps are engineered for efficient and reliable operation in heavy-duty dredging, mining pit dewatering, and slurry transfer applications. With a hydraulically driven wet-end and robust cutters, these pumps handle highly concentrated abrasive slurries with high uptime and minimal maintenance.

Equipped with pump-end, hydraulic agitators and teeth, the SDP Series ensures effective agitation and consistent solids suspension, even with compacted or coarse material. The pumps are built using wear-resistant Ultrachrome® A05 alloy and feature integrated suction strainers to prevent clogging by oversized particles.

The SDP Series can be mounted on excavator arms via quick-hitch plates or operated as part of a complete dredging pontoon system with Multiflo® booster pumps and Linatex® hosework. This flexible and economical alternative to traditional “truck and shovel” methods reduces labor, fuel, and carbon footprint while increasing operational safety.

Custom engineered-to-order solutions are available to match specific site conditions, supported by a global service and training network.
