Simplex Basket Strainers

Simplex basket strainers house a single removable basket in a vertical-chamber body: flow passes into the basket, debris stays behind, and clean liquid leaves the outlet — cleaned by opening the cover and lifting the basket, which means a brief line shutdown for each service. The range covers bodies in carbon steel, CF8, CF8M, CF3M, cast iron, SS304 or SS316 with SS304 to SS316L baskets, A105/F304/F316-class covers and A193 B7/B8/B8M bolting, DN25 to DN400 at Class 150 to Class 300, built to ASME B16.34 with ASME B16.25 ends and API 598 testing. Selection turns on line size and class, basket material and perforation versus particle load, and whether the process tolerates the intermittent isolation a simplex design needs for basket cleaning.
