Here is a new, original online article written in a professional and SEO-optimized style. It naturally incorporates your required keywords — low pH slurry pump, high specific gravity slurry pump, and agitator dredge pump — while fully detailing the DRH400 system.
Advanced Low pH and High Specific Gravity Slurry Pump Solutions for Heavy-Duty Dredging
Industrial dredging projects often involve aggressive environments where conventional pumping systems fail. Applications such as mining, oil & gas, and deep harbor maintenance require a low pH slurry pump capable of handling corrosive mixtures and a high specific gravity slurry pump designed for dense, abrasive materials. Ace Centro Enterprises (ACE) delivers robust dredging solutions engineered to perform reliably under these extreme conditions.
A standout solution in this category is the DRAGFLOW DRH400 self-propelled dredge with steel cables, equipped with an advanced agitator dredge pump for maximum slurry handling efficiency.
DRH400 Self-Propelled Dredge with Steel Cables
The DRH400 is a heavy-duty cable dredger developed for continuous operation in deep harbor and industrial dredging projects. Powered by the high-performance DRAGFLOW HY400 hydraulic dredging pump, the system is capable of managing the toughest dredging tasks with ease.
Its modular pontoon dredger design ensures easy transportation and flexible deployment at any depth, while maintaining stable operation in corrosive, low-pH slurry environments commonly encountered in mining and industrial applications.
Agitator Dredge Pump Technology for Dense Slurry Handling
At the core of the DRH400 system is Dragflow’s advanced agitator dredge pump, specifically engineered to loosen compacted sediments and maintain consistent slurry flow. The integrated agitator enables the pump to efficiently lift and convey slurry mixtures containing mud, slime, silt, sand, and gravel.
This design allows the pump to function effectively as both a low pH slurry pump and a high specific gravity slurry pump, ensuring dependable performance in demanding conditions.
High Specific Gravity Slurry Pump Performance
The DRAGFLOW HY400 pump is designed to handle dense slurry mixtures with specific gravity levels of up to 1.7, making it ideal for heavy-duty dredging operations.
Key Performance Capabilities:
Slurry handling up to 1.7 specific gravity
Solids handling from 20 mm to 120 mm (5 inch)
Maximum flow rates of 4000 m³/hr
Pumping distances up to 1500 meters, extendable with booster pumps
Proven dredging depths of up to 300 meters
Low operating speed reduces mechanical stress, minimizing wear and extending component service life.
Engineered for Low pH and Abrasive Environments
Dragflow dredging pumps are built with durability and corrosion resistance in mind. The advanced sealing system features:
Best-in-class lip seal with front deflector
Teflon layers resistant to both high and low pH
Precision-machined components for long-term sealing integrity
Grease injection points for extended seal life
All wear parts are manufactured from High Chrome Alloy, ensuring superior resistance to abrasion and erosion.
Optional temperature sensors in the motor and moisture sensors in the oil chamber provide additional protection during continuous operation.
