The 16/14 Gravel Sand Pump is an ultra-heavy-duty centrifugal slurry pump designed for extreme-duty material handling in large-scale dredging, mining, and industrial applications. With a 16-inch (400mm) suction inlet and 14-inch (350mm) discharge outlet, this pump delivers unmatched slurry transport capacity, making it ideal for high-volume sand, gravel, and mining operations.
Engineered for maximum durability, it features premium wear-resistant materials (Cr30, ceramic lining, or rubber-coated) to withstand highly abrasive slurries while maintaining high efficiency and low maintenance costs.
✅ Mega-Capacity Performance
Flow rate: 2,500–6,000 m³/h (up to 26,400 GPM)
Max head: 80m (262 ft) for long-distance slurry transport
Handles particles up to 150mm (6 inches)
✅ Ultra-Durable Construction
Cr30 high-chrome alloy (30% chromium) or ceramic-lined for extreme wear resistance
Reinforced double-wall casing for structural integrity
Replaceable wear parts (impeller, liner, shaft sleeve) for easy maintenance
✅ Heavy-Duty Engineering
Extra-large bearings with oil lubrication for continuous operation
Multiple sealing options (mechanical seal, expeller, or gland packing)
Robust shaft design to prevent deflection under extreme loads
✅ Customizable Configurations
Horizontal, vertical, or submersible models
Diesel, electric, or hydraulic drive (up to 1,200 HP/900 kW)
Explosion-proof & corrosion-resistant variants available
