Sand Suction Dredging Pump For Slurry

This dredging pump is a single-stage, single-suction, horizontal centrifugal pump engineered specifically for the demanding conditions of dredging operations. Its design is centered around real-world application requirements, offering exceptional adaptability to the installation space on the vessel, the chosen dredging method, required capacity, and sediment type. With its high-flow design and robust transport capability, it is a versatile solution capable of supporting dredging projects of all scales, from small river maintenance to major port expansion projects.

Featuring optimized, wide flow passages and a high-efficiency impeller, the pump reliably handles solid particles up to 350mm in size and slurry with solids concentrations as high as 50-60% by volume, offering excellent clog resistance. Combined with superior low NPSHr (Net Positive Suction Head required) characteristics, it achieves greater suction depths, ensuring consistent and stable priming performance for deep dredging operations.

The pump series offers flexible configurations: models 200-500WN feature a single-wall casing, while models 600-1000WN are built with a robust double-wall casing. Both can be supplied with either a standalone base or an integrated pump-tank skid. The front pull-out design, coupled with a heavy-duty trapezoidal thread connection between the impeller and shaft, allows for rapid disassembly and assembly of key wetted parts using specialized tools, dramatically reducing on-site maintenance downtime.

Multiple drive options are available, including diesel engines and electric motors. Larger models can be equipped with an electro-hydraulic tilting mechanism for quick inspection of the impeller cavity. A full range of sealing solutions is offered, from mechanical seals to gland packing. Specifically designed for large-bore models, the L-type helical rubber sleeve seal ensures near-zero leakage operation, meeting the demanding sealing requirements of diverse and challenging conditions.

Benefiting from advanced hydrodynamic optimization, the pump achieves efficiency gains of 2-3% above typical industry standards, resulting in significant energy savings. Its wide and flat performance curve allows for flexible matching of varying flow and head requirements by adjusting impeller speed or diameter, demonstrating outstanding adaptability and stable operation even under fluctuating conditions such as changes in discharge distance.

Coal transportation - Horizontal slurry pumps are used in coal washing plants to convey high-concentration coal sludge and tailings, ensuring efficient handling of abrasive materials and reducing downtime.
Metallurgical transportation - They are specifically designed for transporting metallurgical slurries during the smelting process, featuring high wear resistance and corrosion resistance, and can maintain stable production in harsh environments.
Small-sized B sand pumping - Used for offshore dredging, moving seawater mixed with sand using corrosion-resistant materials, ensuring reliability in harsh marine conditions.
C construction slurry transportation - Used for clearing slurry and debris at construction sites, with a no-clogging function, ensuring efficient cleaning and maintaining project schedules.
River sand and field sand mines - Specifically designed for riverbed sand mining operations, featuring a sturdy and low-maintenance design to ensure reliable performance in challenging environments.
