Dredging pumps usually adopt centrifugal design, relying on high-speed rotating impellers to generate centrifugal force, so that the slurry mixture enters the pump body from the suction port, and is pressurized before being output from the discharge port.
The key features include:
Wear resistant design: The overcurrent components (impeller, pump casing) are made of high chromium alloy, rubber lining or ceramic coating to resist abrasion.
Large channel structure: The wide channel design can avoid blockage and allow larger particles (usually up to 30%~50% of the pump diameter) to pass through.
Cavitation protection: Optimize the hydraulic model to reduce the risk of cavitation and ensure stable operation in high concentration media.
Compact structure, easy to install and maintain, suitable for fixed or small mobile dredging platforms.
2. Vertical dredging pump
Vertical arrangement, space saving, commonly used in ship dredging systems.
3. Submersible dredging pump
The motor and pump body are integrated for direct underwater operation, suitable for deep water areas.
4. Cutting suction dredging pump
Equipped with a rotating cutter, cutting and suctioning at the same time, used for crushing hard soil layers or rocks.
Lift: 10~150 meters
By particle size: 5-300 mm
Solid concentration: up to 70% by weight
Water conservancy engineering: river widening, reservoir dredging.
Environmental governance: cleaning of polluted sediment and tailings treatment.
Land reclamation: pumping sand from the seabed and blowing it onto the land.
Intelligent control: Modern dredging pumps are equipped with flow and pressure sensors, which can be linked to the dredging system for automatic adjustment.
Modular design: facilitates the replacement of vulnerable parts and reduces downtime.
1. Medium characteristics (particle size, hardness, concentration);
2. Working environment (water depth, salinity, pH value);
3. System matching (power source, pipeline resistance, conveying distance).
