The 12” Suction Strainer, manufactured by The Hellan Strainer Company, is designed to operate on the suction side of a pump. It employs two handwheel-equipped rotating screens and rigid scraper bars to remove solids from the surface of the screens when the handwheels are rotated. The strainer has six inspection ports for adjustment of the scraper bars. The strainer has two drain ports and two backwash inlets. The strainer internals are made from Monel 400 and the body is made from B61 Bronze.
