Longteng Machinery, a professional manufacturer of slurry pumps

Gravel Pump – SG

The Longteng SG Gravel Pump is a centrifugal pump designed for transporting slurry containing large solid particles, including sand, gravel, rocks and other coarse abrasive materials. It is suitable for applications where conventional slurry pumps may not provide sufficient solids-passage capability.With a single-casing structure, clamp-band connection and wide flow passage, the SG series is designed for continuous coarse-material handling in dredging, river sand extraction, mining and metallurgical applications.The selection of a suitable model depends on particle size, slurry concentration, required flow rate, total head and installation conditions.

High Head Gravel Pump – SGH

The Longteng SGH High Head Gravel Pump is designed for transporting sand, gravel, rocks and other coarse, abrasive solid-liquid mixtures in pumping systems with demanding head requirements. It is intended for applications where both solids passage and hydraulic performance need to be considered, including dredging, mining and long-distance gravel transfer. Compared with a standard gravel pump, the SGH is intended for duties requiring higher head performance. The correct configuration depends on the required flow rate, total dynamic head, particle characteristics, pipeline layout and operating conditions. For project evaluation, provide the actual pumping duty and material information rather than selecting a pump based on transportation distance alone.

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.
