Seawater High Pressure Pumps

WS Series industrial high pressure plunger pumps are engineered for seawater, high-chloride, and corrosive industrial environments. All models feature Duplex 2205 stainless steel fluid-end manifold, providing superior resistance to chloride corrosion, pitting corrosion, and stress corrosion cracking in demanding marine applications.

The WS Series is widely used in marine engineering, offshore platforms, desalination systems, aquaculture, seawater circulation, industrial cleaning, and large-scale water transfer systems. The product range covers low pressure ultra high flow applications to medium and high pressure industrial systems.

Duplex 2205 Stainless Steel Seawater Advantage

All WS Series pumps utilize Duplex 2205 stainless steel fluid-end pump heads. Compared with conventional 316 stainless steel, Duplex 2205 provides significantly improved corrosion resistance and higher mechanical strength in seawater and chloride-rich environments.

• Excellent resistance to chloride corrosion and pitting
• Superior stress corrosion cracking resistance
• Higher mechanical strength than 316 stainless steel
• Suitable for continuous-duty seawater circulation systems
• Reduced maintenance downtime in marine environments

For general industrial water applications, 316 stainless steel configurations are also available for cost-effective non-seawater systems.

FAQ

Why is Duplex 2205 better for seawater pumps?

Duplex 2205 stainless steel provides significantly better resistance to chloride corrosion, pitting corrosion, and stress corrosion cracking compared with conventional 316 stainless steel. It is widely used in seawater, offshore, and high-salinity industrial environments where long-term corrosion resistance is critical.

What industries are WS Series pumps designed for?

WS Series pumps are widely used in marine engineering, seawater circulation systems, offshore platforms, desalination plants, aquaculture, industrial cleaning, landfill wastewater treatment, and large-scale industrial water transfer applications operating in corrosive environments.

Can WS Series pumps handle continuous seawater circulation?

Yes. Selected WS Series models are specifically designed for continuous-duty seawater circulation systems. Duplex 2205 fluid-end components help improve durability and reduce maintenance requirements in corrosive environments.

What is the difference between 316 stainless steel and Duplex 2205 pump materials?

Compared with 316 stainless steel, Duplex 2205 offers higher mechanical strength and superior resistance to chloride-induced corrosion. For seawater and offshore applications, Duplex 2205 is generally preferred for improved reliability and longer service life.

Which WS Series pump is suitable for high flow seawater transfer?

WS-12140 and WS-12170 are designed for high flow seawater circulation and large-volume industrial water transfer systems. These models are ideal for applications requiring continuous low pressure, high capacity operation.
