316 Stainless Steel vs Duplex 2205 – Material Selection Guide
Material selection directly affects pump lifetime, corrosion resistance, and total system cost.
316 Stainless Steel
A widely used austenitic stainless steel offering good corrosion resistance in general industrial environments. Best suited for standard water-based systems and moderate operating conditions.
SUS2205 Duplex Stainless Steel
A high-strength duplex stainless steel with significantly improved resistance to pitting, chloride corrosion, and mechanical stress. Ideal for demanding environments such as seawater exposure, high-chloride fluids, and long-term continuous operation.
If corrosion risk is uncertain, Duplex 2205 is typically the safer long-term engineering choice.

Frequently Asked Questions
What is the main difference between 316 stainless steel and SUS2205 duplex stainless steel?
316 stainless steel is suitable for general industrial fluid applications with moderate corrosion conditions. SUS2205 duplex stainless steel provides significantly higher resistance to chloride corrosion, pitting, and mechanical stress, making it more suitable for demanding or long-duty industrial environments.
How do I choose the right material for my application?
If your system operates with clean water or low-corrosion fluids, 316 stainless steel is usually sufficient. If the application involves higher corrosion risk, continuous operation, or uncertain fluid conditions, SUS2205 duplex stainless steel is recommended for longer service life and higher reliability.
Can WS-1770 be used for continuous industrial operation?
Yes. WS-1770 is designed for industrial-duty continuous operation when installed with proper filtration, lubrication, and system configuration.
What industries commonly use WS-1770 pumps?
It is widely used in industrial cleaning systems, pressure boosting systems, fluid transfer systems, manufacturing process equipment, and automated production line integration.
What information is required for pump selection?
To provide accurate pump selection, we typically need flow rate, working pressure, and fluid type. With these parameters, we can recommend the most suitable pump configuration and drive system.
What are the inlet and outlet port sizes?
Inlet: PF 1-1/4 male thread. Outlet: PT 3/4 female thread. Bypass: PT 3/4 female thread.
Does WULI provide OEM or customized pump solutions?
Yes. WULI provides OEM and ODM services for industrial plunger pumps, including material customization, performance adjustment, and system integration support.
What accessories are included as standard?
Standard configuration includes a pressure gauge and a safety valve for system protection and monitoring.
