Seawater High Pressure Pump
Product Description
Pressure: 2000 p.s.i. (140 kgf/cm2) | Suction Volume: 29.6 Liter/Minute
Product Introduction
WS-2030F1 Duplex 2205 Seawater-Grade High Pressure Plunger Pump
WS-2030F1 is an industrial high pressure plunger pump designed for seawater handling, offshore systems, and corrosive industrial fluid applications. Compared with WS-2024F1, this model provides higher flow capacity while maintaining stable continuous-duty operation.
The pump head, cylinder, and manifold are available in Duplex 2205 stainless steel, a seawater-grade material engineered for chloride-rich environments and aggressive industrial fluids. It is widely used in marine engineering, seawater circulation, desalination, and coastal industrial systems where conventional stainless steel pumps may experience premature corrosion failure.
Performance Specifications
- Maximum Pressure: 2000 PSI (140 bar)
- Flow Rate: 29.6 L/min (7.9 GPM)
- Continuous-duty industrial operation
- Heavy-duty crankshaft-driven plunger design
- Stable long-term high pressure performance
Duplex 2205 Seawater-Grade Material Advantage
- Duplex 2205 stainless steel manifold provides superior resistance to seawater, salt spray, and chloride-rich fluids.
- Excellent resistance against pitting corrosion, crevice corrosion, and stress corrosion cracking.
- Mechanical strength is nearly twice that of conventional 316 stainless steel, improving reliability under high-pressure operation.
- Suitable for seawater salinity environments and chloride exposure where standard stainless steel may gradually deteriorate.
- Widely used in desalination plants, offshore platforms, marine piping systems, and coastal industrial facilities.
- Reduces corrosion-related downtime and extends overall equipment service life.
Duplex 2205 stainless steel typically offers significantly better chloride corrosion resistance compared with 316 stainless steel, making it one of the preferred materials for marine and seawater engineering systems.
Engineering Material Data
- Typical PREN range: 35–38 (depending on composition)
- Yield strength approx. 2x higher than 316 stainless steel
- Higher yield strength compared to 316 stainless steel
- Suitable for chloride environments above typical 316 limits
- Recommended for seawater and brackish water systems
Why Duplex 2205 Performs Better in Seawater Systems
Seawater contains high chloride concentrations that can gradually damage conventional stainless steel surfaces. In high-pressure systems, chloride-induced pitting and stress corrosion cracking often become the primary causes of pump failure.
Duplex 2205 combines an austenitic and ferritic microstructure, allowing it to maintain both high mechanical strength and superior corrosion resistance in demanding marine environments.
Compared with standard stainless steel pumps, Duplex 2205 systems typically provide:
- Longer service life in seawater environments
- Lower maintenance frequency
- Reduced risk of manifold cracking and corrosion leakage
- Improved operational reliability for continuous-duty systems
- Better resistance to warm seawater and coastal humidity
※ 316 stainless steel prone to chloride pitting in seawater systems
※ Duplex 2205 significantly reduces stress corrosion cracking risk in continuous-duty pumps
316 Stainless Steel Option
WS-2030F1 is also available with a 316 stainless steel manifold configuration for general industrial applications.
316 stainless steel is suitable for:
- Clean water transfer systems
- Industrial cleaning equipment
- Mild chemical applications
- Cooling circulation systems
- Industrial misting systems
- General factory washing systems
However, for seawater, coastal environments, high chloride concentration, or corrosive chemical fluids, Duplex 2205 is strongly recommended for improved long-term durability.
