Bronze Submersible Seawater Pump

Designed for harsh marine environments, the Bronze Submersible Seawater Pump is engineered for high-efficiency transfer of seawater, brine, and other corrosive fluids. This design come from more than twenty years experience from Aote tianjin pump co.,ltd. Some mining companies use it to treat tailings water. It’s centrifugal pump with closed impellers. The motor is water-filling and sealed 3phase asynchronous motor.

Applications

1. Marine & Shipbuilding – Bilge pumping, engine cooling water supply
2. Desalination Plants – Seawater intake and brine transfer
3. Offshore Platforms – Sea lift pumps, fire-fighting systems
4. Aquaculture & Fisheries – Pond circulation
5. Coastal Infrastructure – Dock drainage, harbor maintenance

Key Features

1.Corrosion-Resistant Bronze Construction

There are high-quality aluminum bronze or silicon bronze can be chosen, providing exceptional durability in seawater, brackish water, and chlorinated environments.

2.Submersible IP68 Protection

Fully sealed motor casing with IP68 rating allows continuous underwater operation at depths up to 20 meters.

3.High Flow & Head Performance

Hydraulic design optimized for low NPSH requirements, delivering stable performance even with sandy or saline intake conditions.

4.Double Mechanical Seal

Silicon carbide mechanical seals ensure leak-free operation and protect the motor from seawater ingress.

5.Thermal Protection

Prevent damage from dry running.

FAQ

Why choose bronze instead of Bronze Submersible Seawater Pumps?

Stainless steel grades perform differently in seawater environments. Some grades may suffer from chloride-induced corrosion. Marine bronze alloys have been widely used in marine equipment because of their proven resistance to seawater corrosion and erosion.

How long can a bronze seawater pump operate?

The service life depends on operating conditions, water quality, duty cycle, and maintenance. Compared with conventional materials, bronze construction significantly improves corrosion resistance and reduces replacement frequency.

Can this pump handle seawater with sand particles?

The pump can handle normal seawater intake conditions. For seawater containing higher levels of sand or suspended solids, hydraulic design and material selection should be evaluated according to project requirements.

Can you supply pumps for shipbuilding projects?

Yes. We provide customized seawater pump solutions for shipyards, marine equipment suppliers, and offshore engineering projects.
