Basket Filters & Strainers — Prefiltration Series
Custom Filter Baskets & Perforated Filter Tubes
Product Overview
SINFT stainless steel basket filters are custom metal filter elements used for coarse and medium filtration in pipelines, strainers and process housings. These reusable filter baskets capture large solid particles before the fluid reaches pumps, valves, instruments, nozzles or downstream fine filters.
Elements can be made from perforated plate, woven wire mesh, sintered mesh or combined structures. Standard basket filters, slanted baskets, perforated filter tubes, flanged tube strainers and handled basket designs are available according to your drawing, old sample or housing dimensions.

Perforated Basket Details
Multiple hole sizes, machined flange and optional Viton sealing ring help improve sealing inside the basket strainer housing.
The raised lug on the outer diameter of the flange matches the milled notch on the inner diameter of the machined flange welded to the top of the filter basket.
The quick-release handle connects directly to the machined flange of the perforated basket, making removal, cleaning and replacement easier during maintenance.
The filter basket can be supplied with a quick-release handle, and the wire mesh liner basket can be installed inside the perforated basket before the assembly is placed into the strainer housing.
SINFT filter baskets can be equipped with removable wire mesh liner baskets. This mesh liner basket uses a stainless steel screw-in angle ring and a removable handle. A gasket is installed at the bottom of the screw-in ring to help maintain a reliable seal between the perforated filter basket and the wire mesh liner basket.
The wire mesh liner basket can be manufactured with any required mesh specification. All mesh liner basket seams are continuously welded, with no loose wires. Our manufacturing process keeps a close fit between the outer diameter of the mesh liner basket and the inner diameter of the perforated basket, regardless of mesh size or thickness. This close fit remains consistent from basket to basket, supporting full interchangeability.
Testing Equipment

Cleaning & Replacement Guide
When solids build up inside the basket, pressure rises and flow decreases. The basket should be removed, cleaned and checked for mesh deformation, broken welds, damaged rim or blocked openings before reinstallation.
Use the video as a visual reference for cleaning reusable stainless steel filter elements before inspection and reinstallation.
Technical Support
Please provide outer diameter, height, rim or flange size, handle style, bottom style, hole size or mesh count, material, working fluid and photos or drawings of the existing basket.
Yes. Basket filters and strainers are designed for repeated cleaning. Clean the basket when pressure rises or flow drops, and inspect the mesh carefully before reinstalling it.
