Looking for reliable GGH sand and gravel dredging pumps? Our China factory specializes in high-head GH pumps for abrasive slurries in mining and dredging. As professional suppliers, we offer wear-resistant Ni-hard alloys for maximum durability.
The G/GH series Sand and Gravel Dredging Pumps are professional-grade centrifugal pumps engineered for the most demanding slurry transport applications. Featuring a horizontal, single-pump casing structure, these pumps are specifically designed to handle high-concentration gravel and abrasive materials. The GH variant provides enhanced high-head capabilities, ensuring efficient transport of solids across challenging terrains and depths.
To ensure maximum operational longevity, the wet-end components are constructed from premium Ni-hard and high-chromium abrasion-resistant alloys. With a versatile 360° discharge orientation and a wide wet-passage design, the G/GH series offers superior Net Positive Suction Head (NPSH) performance and exceptional resistance to wear, making it the ideal choice for dredging, mining, and industrial slurry management.
| Model Range | 6/4D-G to 18/16T-G | Max Power (kW) | 60kW – 1200kW |
|---|---|---|---|
| Capacity (m3/h) | 36 – 3600 m3/h | Head (m) | 5 – 64 m |
| Rotational Speed | 600 – 1400 r/min | Max Efficiency | 58% – 72% |
| NPSH (m) | 1.5 – 4.5 m | Vane Diameter | 378mm – 1067mm |
| Material Type | High Chrome / Ni-hard | Seal Options | Packing, Expeller, Mechanical |
Utilizing high chromium and Ni-hard alloys to combat the most abrasive gravel and sand particles.
Robust construction and wide wet-passages minimize internal turbulence and material erosion.
360° adjustable discharge direction allows for seamless integration into any plant layout.
Excellent NPSH performance prevents cavitation and maintains steady flow rates.
Choice of mechanical, expeller, or packing seals to suit specific fluid properties.
Clamp band connections enable rapid disassembly for inspection and part replacement.
Customizable alloys including Natural Rubber, Polyurethane, and Stainless Steel.
Precision-engineered expeller and mechanical seals for zero-leakage operation.
Advanced hydraulic design to optimize capacity Q and head H ratios.
Standardized part dimensions for predictable wear cycles and easy scheduling.
Full inventory of impellers and liners for minimized downtime.
Compatible with various slurry pipeline diameters and dredging equipment.
| Performance Metric | Standard Slurry Pump | G/GH Series Pump |
|---|---|---|
| Maintenance Cycle | Short (Frequent Liner Change) | Extended (High Chrome Alloy) |
| Operational Downtime | High due to wear | Low due to rapid-change design |
| Energy Efficiency | Standard η% | Optimized Hydraulic Efficiency |
| Material Handling | Limited particle size | High capacity for large gravel |
| Total Cost of Ownership | Higher over 5 years | Significantly Lower (Long Life) |
The G series is designed for general sand and gravel pumping, while the GH series is specifically engineered for high-head applications, allowing the slurry to be transported over longer distances or higher elevations.
For highly corrosive environments, we recommend Stainless Steel or Natural Rubber linings. For purely abrasive gravel, High Chrome alloys are the industry standard for durability.
It allows the pump to be installed in confined spaces and enables the discharge pipe to be routed in any direction without the need for additional elbows, reducing friction loss and wear.
Expeller seals are often preferred for low maintenance as they eliminate the need for packing adjustment and reduce the risk of shaft wear.
Yes, the G/GH series features a wide wet-passage design specifically to prevent clogging when transporting coarse sand and gravel.
These pumps offer good NPSH performance, which significantly reduces the risk of cavitation, ensuring a more stable flow and protecting the impeller from premature damage.

High Efficiency Froth Slurry Pump for Mineral Processing
In the demanding world of mineral processing and chemical manufacturing, the movement of air-entrained liquids presents a unique engineering challenge. A froth slurry pump is specifically designed to handle these volatile mixtures, ensuring that the valuable froth layer often containing concentrated minerals is transported efficiently without collapsing or losing its structural integrity. The global demand for high-efficiency mineral recovery has pushed the evolution of pumping technology toward specialized designs that can withstand extreme abrasion while managing gas-liquid interfaces. Without a dedicated froth slurry pump, industrial operations often face severe cavitation, inconsistent flow rates, and premature equipment failure, leading to significant downtime
