Core Technical Advantages

　　1. Ultra-Wide Flow Channel for Large Solid Particles The GGH gravel pump adopts a specially enlarged impeller and volute passage, allowing smooth passage of big gravel, coarse sand and bulk sediments. It solves the blockage problem caused by oversized particles in ordinary slurry pumps, ensuring stable continuous operation for heavy dredging tasks.

　　2. High-Chrome Wear-Resistant Wet End Parts All wetted components are made of high-strength high-chromium alloy cast iron. The robust anti-abrasion structure resists severe scouring from gravel, ore slag and hard sediment, greatly extending service life and reducing frequent replacement and maintenance costs.

　　3. G Large-Flow & GH High-Head Dual Versions G model focuses on high-volume river dredging and pond sand extraction; GH high-head version provides boosted pressure for long-distance pipeline slurry transportation. Dual-type design fully covers low-resistance large-flow and high-lift long-distance conveying requirements.

　　4. Flexible 360° Casing Rotation & Clamp Connection Unique clamp-band casing structure allows 360° arbitrary adjustment of the discharge direction. No complicated pipeline modification is needed, making on-site installation, layout adjustment and daily disassembly maintenance extremely convenient.

　　5. Excellent Cavitation Resistance & Stable Operation Optimized hydraulic model improves suction performance and reduces cavitation damage. The heavy-duty bearing bracket ensures low-vibration, 24-hour continuous stable operation under high-concentration and heavy-load working conditions.

　　Main Application Scenarios

　　River & lake dredging, marine channel deepening, sand and gravel mining, dredger supporting pumping, mine coarse tailings transportation, metallurgical slag conveying, reservoir desilting and long-distance slurry pipeline delivery projects.

　　Manufacturer Strength & Service

　　Every G/GH series gravel pump undergoes strict hydraulic performance testing, wear resistance inspection and continuous running aging tests before delivery. We provide professional model selection, customized parameters, complete spare parts supply and full lifecycle after-sales technical support for global dredging contractors, mining enterprises and industrial pump distributors.
