Dragflow DRH400 – Powerful Solution for Gold Mining & Deep Dredging
In gold mining operations, efficiency and durability are critical. A high-performance gold dredge pump must handle abrasive slurry, high solid concentration, and demanding site conditions. The Dragflow DRH400, supplied by Ace Centro Enterprises (ACE), is a heavy-duty self-propelled dredge engineered to meet these exact challenges.
Equipped with the robust Dragflow HY400 hydraulic dredging pump, the DRH400 is designed to manage tough dredging tasks with ease. Its steel cable system ensures operational stability, while the modular pontoon design enables reliable performance at various depths, including environments with low pH slurry mixtures commonly found in mining applications.
