Gorman-Rupp
The new PAV3B60C-3TNV70 three-inch pump uses a patent-pending vortex impeller with Gorman-Rupp’s Staggerwing (staggered-winglet) design. The design allows this model to pass a 3-inch solid through all critical areas of the pump. The pump is powered by a Yanmar water-cooled diesel that is EPA certified to meet Interim Tier IV emission standards. This product soon will be expanded to include an electric motor driven version for use on permanent installations or where engine-driven units are not preferred. 419.755.1011, grpumps.com
