Dredging & Hydraulic Engineering Industry
Used for port dredging, river desilting, waterway maintenance, marine engineering, and land reclamation projects.
CWN Dredge Pump
The CWN dredging pump is specially designed for river dredging, sand mining and land reclamation, and port desilting operations. Featuring high-chromium wear-resistant alloy wet-end parts, it offers advantages such as large flow rate, deep suction lift, high wear resistance, and high efficiency. It can stably convey high-concentration slurry, sand, gravel, and mineral pulp media, making it an ideal choice for various dredging projects.
