Sand Dredge Pumps
What Is a Dredger Pump?
SMI Pumps Dredger Pumps are high-efficiency centrifugal pumps designed for the demanding transfer of sand, sediment, slurry and other abrasive materials encountered in dredging operations. They are engineered to provide reliable, high-capacity performance across river dredging, harbour maintenance, marine sand mining, land reclamation and other heavy-duty applications.
Design & Construction
SMI Dredger Pumps are designed to deliver high flow rates and high heads, providing the pumping capacity required for transporting sediment and slurry over extended distances.
Pump casings, impellers and other critical wet-end components are manufactured from high-chromium alloys and wear-resistant materials selected to withstand highly abrasive operating conditions.
Open or semi-open impeller designs provide generous internal passages, allowing the pump to handle larger solids while reducing the risk of clogging and maintaining consistent slurry flow.
Depending on the application and operating requirements, shaft sealing arrangements can include gland seals, mechanical seals or expeller seals. These systems help prevent abrasive slurry from entering the bearing assembly, supporting reliable operation and extended component life.
Typical Applications
River, Lake & Harbour Dredging
Removal and transportation of accumulated sand, silt and sediment to maintain waterways, channels and harbour depths.
Marine Dredging & Land Reclamation
High-volume transportation of sea sand and dredged material for reclamation, coastal development and construction projects.
Mining & Tailings Handling
Transfer and discharge of abrasive tailings, sediment and slurry generated during mining and mineral processing operations.
Water & Civil Engineering Projects
Suitable for dam maintenance, lake management, waterway rehabilitation and other projects requiring dependable sediment removal and transportation.
Built for Demanding Dredging Operations
SMI Pumps Dredger Pumps combine high-capacity performance, large solids handling, abrasion-resistant construction and dependable operation to provide an effective pumping solution for challenging dredging, mining and sediment-handling applications.
