At Afility Industrial Filters Pvt. Ltd., A duplex strainer, also known as a twin basket strainer, is a type of industrial filtration device designed to remove solid particles from liquids in various fluid handling systems. Its primary purpose is to prevent contaminants, such as debris, dirt, scale, and other foreign particles, from entering downstream equipment or processes, ensuring the smooth operation and longevity of machinery and components.
The term "duplex" indicates that the strainer is equipped with two separate filtering baskets or chambers. This design feature allows for continuous filtration even during maintenance or cleaning procedures. When one basket becomes clogged or requires cleaning, the flow can be switched to the other basket while the maintenance is performed on the first one. This arrangement ensures uninterrupted fluid flow and minimizes downtime in critical applications.
Duplex strainers are commonly used in industries such as oil and gas, petrochemical, chemical processing, water treatment, power generation, and various manufacturing processes where the purity of the liquid is essential. They are often installed in pipelines, process equipment, and pumping systems to safeguard pumps, valves, heat exchangers, and other sensitive components from potential damage caused by particulate matter.
Uninterrupted flow is crucial for efficiency in industrial processes. Duplex strainers facilitate continuous operation by trapping particles and allowing clean fluids or gases to pass through, preserving the efficiency of the system.
These strainers come in various sizes, materials, and configurations, allowing for customization based on the specific needs of the system. They can also be scaled up or down to accommodate different flow rates and particle sizes.
