Stainless Steel Saltwater Pump Engineered for Extreme Marine Environments Built to Last in Coastal Marine Seawater Desalination Systems

Stainless Steel Saltwater Pump Engineered for Extreme Marine Environments Built to Last in Coastal Marine Seawater Desalination Systems

Ideal For: Coastal Infrastructure | Offshore Platforms | Seawater Desalination Plants | Aquaculture | Shipboard Systems | Power Generation | Industrial Brine Handling

In harsh, high-salinity environments—where standard pumps corrode within months—downtime isn’t just costly; it’s catastrophic. With nearly 40 years of precision pump manufacturing experience, we’ve engineered a stainless steel saltwater pump that doesn’t just survive the sea—it thrives in it.

Corrosion-resistant. Energy-efficient. Maintenance-minimized. Built for decades of reliable service.

Key Features: Where Engineering Meets Endurance

✅ Premium Corrosion-Resistant Materials

Wetted parts constructed from 316L stainless steel (standard), with optional super duplex (2507) or high-grade alloys for extreme chloride exposure.

Superior to 304 SS—specifically formulated to resist pitting, crevice corrosion, and stress cracking in seawater.

Dual mechanical seals with corrosion-resistant coatings ensure zero leakage and motor protection.

✅ Optimized Hydraulic Design for Seawater

CFD-validated impeller and volute geometry deliver up to 15% higher hydraulic efficiency vs. conventional designs—reducing energy consumption and operational costs.

Large-passageway design minimizes clogging from sand, algae, shell fragments, and other marine debris.

✅ Industrial-Grade Reliability for Continuous Duty

IP55/IP66-rated motors with F-class insulation withstand high humidity, salt spray, and temperature fluctuations.

Heavy-duty bearings and robust shafting extend mean time between failures (MTBF) by 2x or more.

✅ Fully Customizable to Your Project Needs

Available in horizontal, vertical, and marine-mounted configurations.

Voltage/frequency options: 220V, 380V, 440V / 50Hz or 60Hz.

Certifications available: CE, ISO 9001, DNV, ABS, CCS, ATEX (explosion-proof) upon request.

Proven Applications Across Demanding Industries

Seawater Reverse Osmosis (SWRO) Desalination Plants: High-pressure feed, brine discharge, backwash systems

Commercial & Naval Vessels: Ballast transfer, bilge pumping, fire mains, cooling circuits

Coastal Power Stations: Circulating water for condenser cooling

Aquaculture Farms: Seawater circulation, oxygenation, tank drainage

Offshore Oil & Gas Platforms: Utility water, firefighting, process fluid transfer

Municipal Coastal Infrastructure: Flood control, stormwater management, decorative fountains
