Hydroman® Submersible Dredging Sand Pump for Maritime Constructions is a heavy-duty, electric submersible pump designed specifically for maritime construction, coastal restoration, harbor deepening, breakwater projects, and offshore sand extraction. Built to withstand highly abrasive environments, it features a high-chrome wear-resistant impeller, integrated agitator, and non-clogging hydraulic design for handling sand, gravel, and silt mixtures efficiently.
| Component | Material / Feature | Functionality |
| Pump Casing | High-chrome alloy (Cr28) / ductile iron | Withstands abrasion and impact during dredging operations |
| Impeller | High-efficiency open or semi-open design | Ensures large solid-passing capability with minimal clogging |
| Agitator | Integrated high-chrome agitator | Breaks up and suspends sand, silt, and debris at suction inlet |
| Motor Housing | Cast iron or stainless steel (IP68) | Encloses sealed submersible motor for underwater use |
| Mechanical Seal System | Dual SIC/SIC seals in oil chamber | Prevents slurry from entering motor, designed for high-pressure environments |
| Bearings | Heavy-duty anti-friction ball bearings | Designed to handle radial and axial loads during continuous dredging |
| Cable Entry Seal | Epoxy or rubber compression system | 100% waterproof connection for harsh offshore conditions |
