(9" x 9") WG1032BHF Suction Outlet Cover (Replacement sold as a WGX1032BHF) is rated for 308 GPM Wall Mounted or 515 GPM Floor Mounted for single or multiple suction outlet use. (12" x 12") WG1033BHF Suction Outlet Cover (Replacement sold as a WGX1033BHF) is rated for 732 GPM Wall Mounted or 812 GPM Floor Mounted for single or multiple suction outlet use (This is a package of four 9" x 9" covers and frames) (18" x 18") In the event of one suction outlet being blocked, the remaining suction outlets serving that system shall have a flow rating capable of the full flow of the pump(s) for the specific suction system. Example: In the System shown in Diagram 1, two (2) 12" Square (WG1032HFPAK2) suction outlet covers are selected and mounted on the floor. These covers are individually rated for 515 GPM. For a desired flow of 130 GPM, a minimum pipe size from Chart 1 is selected at 3". At the desired flow of 130 GPM one cover could be partially blocked and the other suction outlet flow would be below the rated 515 GPM of the remaining suction outlet. Since there are two outlets flowing in normal operation, and the allowable velocity in the branch piping is only 3ft/sec with both outlets flowing, the branch piping would require 3" pipe size. Example: In the System shown in Diagram 2, two (2) 12" Square (WG1032HFPAK2) suction outlet covers are selected and mounted, on one the floor and the other on the wall. These covers are individually rated for 515 GPM on the floor and 308 GPM when wall mounted. For a desired flow of 110 GPM, a minimum pipe size from Chart 1 is selected at 3". At the desired flow of 110 GPM one cover could be partially blocked and the other suction outlet flow would be below the rated 308 GPM of the remaining suction outlet. Since there are two outlets flowing in normal operation, and the allowable velocity in the branch piping is only 3ft/sec with both outlets flowing, the branch piping would require 3" pipe size.
