Flexible Design for Diverse Applications

Duplex basket strainers are engineered to accommodate a wide range of industrial processes. With a variety of connection standards, mesh sizes, and body materials, they are suitable for filtration in pipelines handling liquids or gases such as water, oil, chemicals, and fuel. Their robust, epoxy-painted (or custom) bodies ensure long-term reliability even in demanding environments.

Uninterrupted Operation and Easy Maintenance

The duplex (twin basket) design enables continuous operation by allowing the strainer to be switched to a clean basket while the other is serviced. Manual changeover valves and levers simplify this process, making maintenance without complete system shutdown possible. This structure is ideal for industries where consistent filtration and minimal downtime are crucial.

Customizable to Project Specifications

Offering a wide spectrum of basket mesh sizes, materials, connection types, and coatings, these strainers can be customized to match specific operational and project requirements. Available in multiple port sizes and mounting positions, they are tailored to client needs, ensuring compatibility and efficient pipeline integration.

FAQs of Duplex Strainers:

Q: How does a duplex strainer with stainless steel or brass mesh work in industrial filtration?

A: A duplex strainer consists of two parallel basket chambers equipped with stainless steel or brass mesh screens. When one basket requires cleaning, the flow can be manually switched to the other using a changeover valve, allowing maintenance without interrupting the filtration process. This ensures continuous filtration of liquids or gases in pipelines.

Q: What types of fluids and applications are suitable for these duplex basket strainers?

A: These duplex strainers are designed for use with salt water, oil, chemical solutions, fuel, and water. They are commonly installed in industrial liquid and gas pipelines for applications where removing contaminants and protecting downstream equipment is essential, such as in manufacturing plants, chemical processing, and power generation.

Q: When should the mesh baskets be cleaned or replaced in a duplex strainer?

A: The mesh baskets should be inspected and cleaned or replaced according to the level of particulate contamination and operating conditions. Typically, cleaning is required when flow rates drop or differential pressure increases, indicating that the mesh is clogged. The duplex design allows this to be done without halting the filtration process.

Q: Where are these duplex strainers typically installed within a system?

A: Duplex strainers are usually installed horizontally in pipeline systems, just before sensitive equipment or inlets where fluid purity is crucial. Their robust construction and customizable end connections (ANSI, DIN, JIS, or special options) allow integration into diverse industrial setups.

Q: What is the installation process for setting up a duplex strainer?

A: Installation involves positioning the strainer in a horizontal orientation within the pipeline, ensuring proper alignment with the specified flanged or screwed end connections. After securing the strainer and connecting it to the pipeline, the initial basket is placed, and the unit is tested for leaks and proper valve operation.

Q: How does the manual operation and changeover mechanism benefit users?

A: Manual operation with a changeover lever or handle provides simple and reliable control, eliminating the need for electrical power sources. This allows users to swiftly switch between baskets for cleaning or maintenance, reducing downtime and maintaining continuous filtration efficiency.

Q: What are the advantages of choosing customizable options for duplex strainers?

A: Customizable options for mesh size, body material, mounting position, color, and port size ensure the strainer precisely matches the operational needs and constraints of each application. This maximizes compatibility, efficiency, and service life while supporting a wide range of industrial processes.
