This machine is a centrifugal trash pump. The Wacker Neuson Trash Pump consists of a tubular steel frame surrounding a gasoline or diesel engine, a fuel tank, and an impeller pump with ports for water suction and discharge. The engine rotates the impeller during operation. Waste water is drawn into the pump through the suction port and expelled through the discharge port. The operator connects hoses to the pump and routes them so that water and solids are drained from the work area and discharged into an appropriate location.
