Sand and Slurry Pumps

Sand and slurry pumps are key equipment in dredging, mining, and power industries, used to transport highly abrasive media containing a high concentration of solid particles.

Core Product Characteristics and Technical Parameters

Sand and slurry pumps are centrifugal impurity pumps, characterized by high wear resistance, non-clogging operation, and strong sewage discharge capacity. They typically employ a dry-type submersible pump design with the motor and pump integrated on the same shaft, or a single-casing, cantilever structure. In addition to the main impeller, a stirring impeller is often added at the bottom to agitate the sediment into turbulent flow before extraction, achieving high-concentration transport.

Technical Advantages

Wear-resistant and durable

Flow components are made of wear-resistant materials such as high-chromium alloys.

High efficiency and non-clogging

Wide flow channel with excellent anti-clogging performance.

Reliable sealing

Employs mechanical seals or multiple seal combinations to effectively prevent high-pressure water and impurities from entering the motor.

Product Parameters

Diameter:	100-400mm
Flow Rate:	57-3348m³/h
Head:	14-78m

Selecting a suitable sand and slurry pump and maintaining it correctly are crucial for ensuring its long-term stable operation.

Key Factors for Scientific Selection

Media Characteristics

Accurately analyze the specific composition, particle hardness, shape, particle size distribution, and specific gravity of the medium.

Operating Parameters

Determine the required flow rate, head, operating temperature, pH value, and the pump's submersion depth or installation method.

Material Matching

Select matching materials for the flow-through components based on the abrasiveness and corrosiveness of the medium.

Professional Consultation

Provide operating information to multiple professional manufacturers to obtain their selection advice and quotations for comprehensive comparison.

Application Areas

Water Conservancy Dredging Projects: Dredging operations in rivers, lakes, and ports, as well as the transportation of silt and gravel during channel widening and deepening.
Mining and Quarrying: Transportation of crushed stone and gravel in quarries; transportation of rock cuttings and slag during mining stripping operations; drainage and tailings transportation in open-pit mines.
Construction and Infrastructure: Transportation of sand and gravel in land reclamation and dike construction; transportation of slag and mud during shield tunneling and tunnel excavation; transportation of sand and gravel during roadbed filling.
Metallurgy and Coal: Transportation of blast furnace slag and steel slag in steel plants; transportation of coarse coal slime and coal gangue in coal washing plants; and transfer and treatment of metallurgical waste.
Other Applications: Drainage of hydropower station dam foundation pits; reservoir dredging; mud and sand handling during bulk cargo loading and unloading at ports and wharves; and transportation services for dredging vessels.
