Shijiazhuang Ruite Pump Co., Ltd. is one of the most reliable manufacturers and suppliers of dredging sand pump in China. Welcome to wholesale durable dredging sand pump made in China here from our factory. All pumps are with high quality and competitive price.
Key Functions
Handling Large Particles
The pump's flow-passing components (such as the impeller and pump casing) are designed with wide flow channels to prevent blockages caused by large solid particles.
Wear and Corrosion Resistance
Flow-passing components are typically made of wear-resistant materials, such as high-chromium alloys, to withstand the severe abrasion from silt and potential chemical corrosion.
Key Role
Provides an integrated "dredging-conveying-discharging" operation for the suction and discharge systems of dredgers (such as cutter suction dredgers and suction dredgers).
Main Types
Cutter-suction dredger pumps
Typically equipped with one or two units, installed in pump compartments in the midship or stern, these work in conjunction with the cutterhead at the bow to efficiently draw in sediment loosened by the cutter. They are usually powered by diesel engines.
Bucket-type dredger pumps
Installed at the bottom of the vessel, these pumps are connected via piping to the bucket head at the stern or side of the vessel. They are responsible for both sucking in slurry from the seabed through the bucket arms and pumping it into the vessel's slurry tank.
(Heavy-duty) Bucket-wheel dredger pumps
Their pumping characteristics are highly similar to those of cutter suction dredgers, with an emphasis on wear resistance and high flow rates.
Suction cup/jet dredger pumps
These use high-pressure water pumps to wash the seabed and create slurry, which is then sucked away by a slurry pump. This involves a combination of high-pressure clean water pumps and slurry pumps.
Main Application Areas
Water Resources and Waterway Engineering
Dredging and desilting of rivers, lakes, and reservoirs; maintenance and deepening of waterways.
Port and Coastal Engineering
Port construction, channel excavation, land reclamation, and artificial island construction.
Underwater Mining Industry
Mining in rivers, lakes, and seas.
Key Considerations for Selection and Usage
Medium Characteristics: Particle size, concentration, specific gravity, hardness, and corrosiveness of the conveyed medium.
Performance Parameters: Determine appropriate flow rate, head (pressure), and power based on project requirements.
Wear-Resistant Materials: Select metal materials (such as A05 or A49 high-chromium alloys) based on the severity of wear.
Cavitation Issues: Ensure the pump's installation location has sufficient net positive suction head (NPSH) to prevent cavitation damage to the impeller and efficiency loss.
Power Matching: The power rating of the drive unit (electric motor/diesel engine) must have sufficient margin to accommodate fluctuations in operating conditions.
Maintenance and Spare Parts: Regularly inspect wear on flow-through components such as the impeller, wear plates, and pump casing, and maintain a stock of wear-prone parts.
