The Subaru Robin Semi-Trash Series pumps employ deeper
impeller vanes, along with a larger volute discharge opening, to pass water containing suspended particulate matter and small solidobjects. The new pumps, available with either 2-inch (model PKX201ST) or 3-inch (model PKX301ST) inlets and outlets, have the capacity to move 153 and 246 gpm, respectively. The 2-inch model can accommodate solids to 1/4 inch in diameter, and the 3-inch model can handle solids to 3/4 inch in diameter. The new pumps use Subaru Robin air-cooled, four-stroke-cycle gas engines of 4.5 and 6 horsepower, respectively.
