WS-1770 Duplex 2205 High Flow Seawater Plunger Pump

The WS-1770 is a high-capacity industrial plunger pump designed for seawater circulation, marine operations, and high-volume industrial fluid transfer. Its primary design focus is high flow performance (73.3 L/min) for systems that require large-scale water movement rather than high-pressure output.

The pump can be configured with a Duplex 2205 seawater-grade fluid end, providing excellent resistance to seawater, chloride-rich environments, and aggressive marine conditions.

Performance Specifications

• Operating Pressure: 1700 PSI (120 bar)
• Flow Rate: 73.3 L/min (19.3 GPM)
• Heavy-duty crankshaft-driven plunger design
• Continuous-duty industrial operation
• Optimized for high-volume fluid transfer systems

Duplex 2205 Seawater-Grade Material Advantage

• Duplex 2205 fluid end provides excellent resistance to seawater and salt spray corrosion
• High resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking
• Significantly higher mechanical strength compared to 316 stainless steel
• Ideal for long-term operation in high-chloride marine environments
• Suitable for offshore, coastal, and continuous seawater circulation systems

Duplex 2205 is widely used in marine engineering applications due to its superior balance of strength and corrosion resistance, especially in environments where 316 stainless steel may suffer from chloride-induced degradation.

Why WS-1770 is Ideal for High Flow Seawater Systems

Unlike high-pressure pump designs, the WS-1770 is optimized for large-volume seawater movement and circulation. This makes it particularly suitable for systems where flow rate is more critical than pressure.

• Seawater circulation and transfer systems
• Ship deck and hull cleaning systems
• Aquaculture and fish farming water supply systems
• Coastal industrial cooling systems
• Marine cleaning equipment and washdown systems

When equipped with Duplex 2205 components, the WS-1770 maintains stable long-term performance in corrosive seawater environments while reducing maintenance downtime.

316 Stainless Steel Option (Alternative Configuration)

The WS-1770 is also available in a 316 stainless steel configuration for general industrial applications where seawater exposure is limited.

• Clean water transfer systems
• General industrial washing equipment
• Cooling circulation systems
• Mild chemical fluid handling

For seawater, offshore, or high-chloride environments, Duplex 2205 is strongly recommended for improved durability and extended service life.
