Dragflow DRH400 – High-Performance Self-Propelled Dredging System
For demanding marine and industrial applications, a reliable submersible dredge pump is essential to ensure efficient material handling and long-term operational performance. The Dragflow DRH400, supplied by Ace Centro Enterprises (ACE), is a heavy-duty self-propelled dredge equipped with steel cables and engineered for deep harbor dredging across marine, mining, and oil & gas industries.
At the heart of the DRH400 is the powerful Dragflow HY400 hydraulic dredging pump, specifically designed to tackle high-density slurry mixtures with ease. Built on a modular pontoon platform, this dredger operates efficiently at varying depths and performs exceptionally well even in low pH slurry conditions.
