The 14/12 Sand Dredge Pump is an ultra-heavy-duty centrifugal slurry pump engineered for large-scale sand dredging, mining, and high-capacity slurry transport. The designation "14/12" refers to its 14-inch (355mm) suction inlet and 12-inch (300mm) discharge outlet, making it ideal for industrial, marine, and mega-infrastructure projects requiring massive material handling.
Designed for extreme abrasion resistance, this pump features high-chrome alloy (Cr30), rubber lining, or ceramic composites to withstand continuous operation with highly abrasive slurries. Its optimized hydraulic design ensures maximum efficiency, low maintenance, and long service life even in the harshest environments.
✅ Ultra-Durable Construction
Cr30 high-chrome alloy (30% chromium) or ceramic-lined for extreme wear resistance
Reinforced double-wall casing for added structural integrity
Replaceable wear plates, impeller, and shaft sleeve for easy maintenance
✅ High-Performance Design
Handles particles up to 120mm (4.7 inches)
Flow capacity: 1,500–4,000 m³/h (up to 17,600 GPM)
Max head: 70m (230 ft) with optimized impeller design
Efficiency up to 80% for reduced energy costs
✅ Heavy-Duty Components
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 heavy loads
✅ Customizable Configurations
Horizontal or vertical mounting
Diesel, electric, or hydraulic drive options (up to 800HP/600kW)
Explosion-proof, submersible, or dry-installation models
