Heavy-duty Non-blocking Gravel Pump

The Gravel Pump is a heavy-duty industrial pump designed specifically for handling highly abrasive media containing large, hard solids such as sand, gravel, and crushed stone. Its core advantages are exceptional wear and impact resistance, along with a wide flow passage that allows large solid particles to pass through smoothly. It is particularly suitable for the continuous and stable transportation of high-concentration, coarse-particle slurries. Typical applications include dredging, mining tailings, sand extraction, and construction aggregate slurry handling.

Heavy-duty structure, sturdy and durable
Both the pump body and the pump shaft are designed with thickening and reinforcement, resulting in strong overall rigidity and the ability to withstand continuous high-load operation. Even under harsh working conditions, the equipment maintains low vibration and high stability, ensuring long-term reliable operation.
Based on hard materials, long-lasting wear resistance and impact resistance
The flow components are made of special materials such as high-chromium cast iron and wear-resistant alloy steel, which have high hardness and excellent wear resistance. They can withstand the intense scouring and impact of sand and stone materials for a long time, significantly extending the service life of key components.
Wide flow channels, strong capacity for large particles
With a wide and smooth flow channel geometric design, combined with open or semi-open impellers, the pump can efficiently convey solid particles with a diameter exceeding 100 millimeters, effectively reducing the risk of blockage and ensuring continuous and smooth transportation.
Suitable for high concentrations, stable operation
Designed specifically for transporting high-concentration slurries, it can stably handle sand and gravel slurries or mud with a solid volume concentration of up to 40%. It has good adaptability to changes in medium concentration and is not easily affected by concentration fluctuations in terms of transportation efficiency and operational stability.

Waterway dredging: Used for silt removal in rivers, lakes and ports, as well as for transporting sand and gravel during the deepening and widening of waterways.
Mining quarrying: Applicable for transporting sand and stones in quarry sites, handling rock debris during mining stripping, and draining tailings and mine pits.
Construction: Used for transporting sand and stones in land reclamation and embankment projects, discharging waste materials from tunnel shield machines, and transporting materials for roadbed filling.
Metallurgical coal: Can transport high-temperature blast furnace slag and steel slag from steel mills, as well as coal slimes and coal gangue from coal washing plants and other industrial waste materials.
Other fields: Including water conservancy station foundation pit drainage, reservoir silt removal, port bulk cargo handling and dredging vessel supporting transportation, etc.
