Basket strainers protect equipment by mechanically removing solids from liquids and other piping systems with the use of a perforated or wire mesh straining screen in a vertically oriented chamber. Basket strainers have more debris holding capacity than Y strainers, and generally have less of a pressure drop, which is why they are ideal in liquid applications.
Basket strainers are sometimes used in double arrangements so that flow can be diverted while the system remains in service and the screen is cleaned. Basket Strainers feature top removal of the screen. The screen is in the form of a basket, with a lifting handle, so that all particulate captured and retained by the screen can be easily removed for disposal. They are intended for applications where large amounts of solids particulate are expected and where the clean-out will be frequent.
Cleaning of the strainer is accomplished by removing the cover and pulling out the basket, and a bolted top cover flange is provided for ease in basket removal. The high pressure/temperature gasket between the body and cover is spiral wound 304 stainless steel. The BCF strainers have carbon steel hex head cap screws and come with a tapped and plugged NPT drain connection.

Carbon Steel performs exceptionally well in high temperatures, up to 425℃ in continuous service. It provides high resistance to shock, vibration, piping strains, and fire and freezing hazards.
Stainless Steel is highly corrosion resistant, extremely strong, and is commonly specified for high temperature service, up to 550℃ in continuous service. Stainless Steel strainers are commonly found in the chemical, food, and pharmaceutical industries.
