Gravel Pump – SG

Gravel Pump-SG is a centrifugal gravel pump designed for continuous transportation of slurry containing large solid particles that cannot be handled effectively by conventional slurry pumps. With a single casing structure, clamp band connection and wide flow passage design, the pump provides excellent solid passing capability and reliable wear resistance under abrasive working conditions. The wet-end components are manufactured from high wear-resistant alloys, making it suitable for sand, gravel, rocks and mining debris transportation. SG Gravel Pump is widely used in dredging, river sand extraction, mining, metallurgy and other applications requiring stable handling of coarse and abrasive materials.

High Head Gravel Pump – SGH

SGH High Head Gravel Pump is designed for transporting large particle slurry under high resistance and long-distance pumping conditions. Compared with standard gravel pumps, the SGH series provides higher head capability while maintaining strong wear resistance and large solid handling performance. The pump adopts a single casing structure with clamp band connection and wide flow passage design, allowing continuous transportation of gravel, sand, mining debris and other abrasive materials. With high chrome alloy wear-resistant wet-end components and flexible drive options, SGH Gravel Pump is widely used in dredging, mining, tailings transportation, hydraulic mining and industrial slurry pipeline systems requiring higher pressure performance.

WN Dredging Pump

The WN Dredging Pump is a horizontal centrifugal pump designed for high-volume transportation of sand, gravel, sediment and other coarse solid-liquid mixtures in dredging systems. Its wide flow passage and robust wet-end design support the continuous handling of abrasive materials while reducing the risk of blockage.

Heavy Duty Dredging Pump – WN

The Heavy Duty Dredging Pump – WN is designed for large-scale dredging and slurry transportation applications involving sand, sediment, gravel and other abrasive solids. As part of the WN dredging pump range, it is suitable for demanding operating conditions where high flow capacity, durable construction and reliable continuous operation are required.

High Efficiency Dredging Pump – WN

The High Efficiency Dredging Pump – WN is designed for slurry transportation applications where hydraulic efficiency, stable operation and energy consumption are important considerations. The pump uses an optimized hydraulic design to improve energy utilization while maintaining the solid-handling capability required for dredging and slurry applications.
