Understanding Basket Strainers
Basket strainers consist of a cylindrical body, a basket that holds the filter element, and connections for inlet and outlet pipes. The filter element, typically made of perforated metal or mesh, allows fluid to pass through while trapping solid particles. This design ensures efficient filtration and minimal pressure drop.
• Body: The main structure that houses the basket and connects to the pipeline.
• Basket: The filtering element that traps solid particles.
• Connections: Flanges or threaded connections for easy installation and maintenance.
