The duplex strainer typically consists of two cylindrical filter chambers, each with its own inlet and outlet ports. The strainer chambers are connected by a valve assembly that allows for the strainer to be switched from one chamber to the other without interrupting the flow of the liquid being filtered. Each strainer chamber contains a perforated basket or screen that traps debris and prevents it from entering the downstream system.

The duplex strainer operates on the principle of continuous filtration, meaning that one strainer chamber is always in use while the other chamber is being cleaned or serviced. This ensures that the flow rate is maintained at a constant rate and the filtration process is uninterrupted.

The duplex strainer is available in a variety of sizes and materials to accommodate different applications and operating conditions. It can be made of carbon steel, stainless steel, or other alloys, depending on the specific requirements of the application. The strainer baskets or screens can also be made of various materials, including stainless steel, brass, or monel.

• High flow rates: The duplex strainer is designed to handle high flow rates, making it suitable for a variety of industrial applications.
• Continuous filtration: The duplex strainer operates on the principle of continuous filtration, ensuring that the filtration process is uninterrupted.
• Low maintenance: The duplex strainer is designed to be easy to maintain, with the ability to switch between the two strainer chambers without interrupting the flow of the liquid.
• Flexibility: The duplex strainer can be customized to meet the specific requirements of the application, including the size, material, and type of strainer basket or screen.
• Overall, the duplex strainer is a reliable and efficient filtration system that is widely used in industrial applications. Its ability to handle high flow rates, operate continuously, and require low maintenance makes it a popular choice for many different types of industries.
