KW Series ANSI 300 Class Basket Strainer Housings
KW Series ANSI 300 Class Basket Strainer Housings
The KW series, cast stainless steel or carbon steel, ANSI 300 class simplex strainer housings effectively remove dirt, pipe scale, and other contaminants from process liquids such as water, chemical and petroleum products in many industrial filtration applications.
These ANSI class 300 strainers have raised face, flanged ends with sizes available from 2 to 12 inches. Standard housing material is either 316 stainless steel or carbon steel. Housings come equipped with a heavy duty, perforated 304 stainless steel basket. Custom perforation sizes or mesh lined baskets are also available. Models are furnished with gauge taps with plugs on both the inlet and outlet sides. Gauge taps allow for easy installation of pressure gauges to monitor differential pressure which help to determine when basket cleaning is necessary. The straight flow path and slanted design of the straining basket minimize the pressure loss.
