12/10 Dredging Sand Pump

12/10 Dredging Sand Pump - Professional Product Overview

1. Product Description

The 12/10 Dredging Sand Pump is a heavy-duty centrifugal slurry pump specifically engineered for large-scale sand dredging and high-volume slurry transportation applications. The "12/10" designation indicates a 12-inch (300mm) suction inlet and 10-inch (250mm) discharge outlet, making it ideal for industrial-scale operations requiring massive material transfer.

As a workhorse in the dredging industry, this pump features an ultra-robust construction with premium wear-resistant materials to handle the most demanding abrasive slurries. Its optimized hydraulic design ensures maximum efficiency while minimizing energy consumption in continuous operation.
