The 400QJH500-20-45KW is a heavy-duty submersible seawater pump engineered for high-capacity fluid transmission in extreme marine environments. By integrating a Tin Bronze wet-end assembly with a Grade 2205 Duplex Stainless Steel motor, this unit provides a definitive solution to the industry's twin challenges: Severe Corrosion and Bio-fouling.
The pump head and impellers are cast from high-grade Tin Bronze, specifically chosen for its behavior in moving seawater:
Erosion Resistance: Effectively resists the "sand-blasting" effect of high-velocity seawater mixed with particulates.
Bio-Inhibition: Naturally releases trace copper ions to prevent barnacles, algae, and mussels from colonizing the pump internals, maintaining a constant flow rate of $500\text{ m}^3/\text{h}$.
While standard 316L stainless steel is prone to pitting in warm seawater, our 2205 Duplex Stainless Steel motor housing offers:
Superior PREN: A high Pitting Resistance Equivalent Number ensures the motor remains intact in high-chloride concentrations.
Mechanical Integrity: Yield strength is twice that of austenitic steels, allowing for greater immersion depths and structural durability.
The DN200 discharge interface is precision-matched to the 500 cubic meter hourly flow. This balance ensures optimal laminar flow, reducing vibration and mechanical stress on the connected piping infrastructure.
Seawater Desalination: Primary intake for reverse osmosis (RO) systems.
Coastal Industry: Circulating cooling water for power plants and refineries.
Marine Aquaculture: Large-scale seawater exchange for industrial land-based fish farms.
Offshore Engineering: Firefighting, ballast, and platform drainage systems.
Extended Mean Time Between Failures (MTBF): In saltwater medium testing, its performance significantly outperformed standard stainless steel pumps.
Low Lifecycle Cost: Reduced frequency of lifting and cleaning leads to massive savings in labor and equipment downtime.
Advanced Sealing: Features specialized mechanical seals designed specifically for the abrasive nature of seawater.
We provide bespoke engineering adjustments for unique site conditions:
Material Upgrades: 2507 Super Duplex or Nickel-Aluminum Bronze available upon request.
Electrical: Specialized voltage (up to 1140V) and Variable Frequency Drive (VFD) compatibility.
Monitoring: Integrated temperature and leakage sensors for real-time system diagnostics.
