(SIZES 14”, 16”, 20”, 24” 30”, 36”) Type WDA Hellan Strainers employ two electric motor-driven rotating screens and rigid scraper bars to remove solids from the surface of the screens when the screens are rotated. A solids collecting sump is also provided. Cleaning of the Type WDA strainer is initiated when the motors and the flush valve operator are actuated. Controls to
accomplish these electrical functions are provided. The cleaning cycle must be performed when the strainer is operating under a positive pressure. Type WDA strainers can be installed only in a horizontal flow position with the sump connection located at the bottom.
