A strainer is a pipeline component that contains a wire mesh or perforated cylinder. This mesh traps contaminants in the fluid stream and removes them from the system. Dust, debris, sediments, and other unwanted particles get separated when the fluid flows through the strainer’s body.
The main purpose of a strainer is to capture large particles that can obstruct pumps, valves, pneumatic flow control valves, and steam traps. Moving parts inside the system work smoothly when the strainer prevents dust and other particles from interfering.
Strainers also protect equipment from damage caused by particles carried through the process fluid. During system flushing and startup, industries often install strainers upstream of pumps to block construction debris left in the pipeline.
Difference Between a Strainer and a Filter
Although filters and strainers look similar, they perform different functions. A filter uses disposable media to remove fine dust particles of specific micron sizes from gases and liquids. In contrast, a strainer removes larger particles by using a mesh screen or perforated plate.
Unlike filters, strainers are reusable. After cleaning out trapped particles, industries can use them repeatedly. Downstream equipment such as condensers, pumps, and three-way ball valves benefit from strainers because they strengthen and protect the piping system.
Basket Strainer India is widely used in applications where the medium is thicker and contains contaminants. Industries such as food processing, chemical production, water treatment, and oil refining rely on them for efficient fluid handling.
What is a Basket Strainer?
A basket strainer, also called a simplex strainer, gets its name from its basket-like shape. Available in simplex and duplex designs, it is ideal for applications requiring high flow capacity. One major advantage is that it can be serviced without interrupting the flow inside the pipeline.
This type of strainer works well in applications with high contamination levels, open area ratios, and liquid filtration requirements. Basket Strainer India offers reliability for industries that cannot afford downtime.
Industrial Applications for Basket-type Strainer
Basket strainers remove impurities from liquids and ensure smooth operation of pipelines. They are commonly used in liquid service applications where large flow capacity is needed.
Industries often install them at the pump suction to protect pumps, hydraulic ball valves, and other components. The strainer filters out particles or debris larger than the mesh inside the basket.
Operators can easily service basket strainers by removing the cover and accessing the basket. The duplex version has two parallel baskets and diverting valves, which allow continuous liquid flow. While one basket gets serviced, the other basket continues operation, eliminating downtime.
Conclusion
A basket strainer refines liquids by separating them from solid contaminants. It captures unwanted materials such as rust, weld metal, scales, and joints, preventing them from entering the flow line. Basket strainer India protects equipment from damage, reduces maintenance needs, and minimizes downtime in industrial operations.
