LEAKPROOF Simplex Basket Strainers
Fabricated basket strainers with a large dirt-holding capacity and low pressure drop, for lines that can be stopped briefly to clean the basket.
The LEAKPROOF fabricated simplex basket strainer (LPFSB) protects pumps, meters, heat exchangers and valves on water, hydrocarbon and chemical services. A deep basket gives several times the pipe area, so the strainer runs longer between cleanings and holds a low pressure drop.
Bodies are designed to ASME Section VIII Div. 1 / ASME B31.1 with flanges to ASME B16.5. Quick-release covers, internal coatings, linings and special alloys are available for demanding services.
- Sizes 2" to 24" (larger on request)
- Class 150 and 300; higher ratings to order
- RF, FF, RTJ flanged or butt-weld ends
- Perforated basket with replaceable mesh liner
- Quick-release or bolted cover
- Internal coating or lining available
