Stainless Steel Submersible Pump for Seawater Lifting - Corrosion Resistant

Product Description

Stainless Steel Submersible Pump for Seawater Lifting - Corrosion Resistant

The Stainless Steel Submersible Pump for Seawater Lifting - Corrosion Resistant is a high-performance submersible pump specifically engineered for highly corrosive seawater environments and demanding industrial applications. Constructed from corrosion-resistant materials such as 316L stainless steel, duplex steel, and nickel-aluminum bronze, combined with precision manufacturing techniques, this pump ensures reliable and long-term operation in complex and aggressive media. It is widely used in seawater desalination, offshore engineering, aquaculture, shipboard drainage, and industrial wastewater treatment, making it the ideal solution for harsh operating conditions.

Stainless Steel Submersible Pump for Seawater Lifting Core Advantages

Superior Corrosion Resistance

Full stainless steel construction (316L / 2205 duplex steel) and nickel-aluminum bronze impeller provide excellent resistance to seawater, acidic/alkaline liquids, and saline environments, ensuring a service life of over 10 years.

The motor chamber is filled with fresh water for lubrication and cooling, preventing salt fog corrosion and extending motor life.

High Efficiency and Stable Operation

Multi-stage centrifugal or mixed-flow design offers high single-stage head (up to 30-50 meters) and flow rates ranging from 5 to 2200 m³/h, meeting a wide range of operational requirements.

IP68 protection rating with a fully sealed structure enables deep submersion (maximum submersion depth up to 70 meters).

Low Maintenance and Long Service Life

Water-lubricated bearings combined with hard alloy mechanical seals reduce wear and minimize maintenance frequency.

Integrated check valve prevents water hammer impact, ensuring safe start-up and shutdown.

Flexible Customization

Available with various materials (304/316/316L/duplex steel), voltages (380V/660V/1140V), and frequencies (50Hz/60Hz) to meet global standards.

Supports vertical or horizontal installation, suitable for diverse applications including wells, sumps, and offshore platforms.

Stainless Steel Submersible Pump for Seawater Lifting Applications

Offshore Engineering: Cooling water circulation on offshore platforms, drilling fluid transfer, and flood drainage.

Seawater Desalination: Pre-treatment for high-pressure pump arrays and feedwater for reverse osmosis systems.

Aquaculture: Water circulation in fish farms and water supply/drainage for aeration systems.

Industrial Wastewater: Discharge and recovery of saline wastewater from chemical plants and power stations.

Municipal Infrastructure: Rainwater pumping stations in coastal cities and flood prevention in underground garages.

Stainless Steel Submersible Pump for Seawater Lifting Installation and Maintenance Guidelines

Pre-Installation Checks

Ensure the motor chamber is completely filled with clean fresh water (failure to do so will result in motor burnout).

Manually rotate the pump shaft to verify smooth operation without binding.

Operating Requirements

The pump must be fully submerged during operation, with a minimum distance of 2 meters from the seabed to avoid sediment intake.

Install a pre-filter when suspended solids exceed 0.01%.

Maintenance Recommendations

Inspect seal wear and clean the impeller and filter every 2000 hours of operation.

For long-term storage, drain the water from the motor chamber and store in a dry, well-ventilated area.
