Abstract: A method and apparatus for reducing operating costs and emissions in a pumping installation. A first step involves providing a flow dividing apparatus capable of dividing flow from a pump. The apparatus has a single inlet and two or more outlets. A second step involves coupling the flow dividing apparatus with a pump of the pumping installation and directing flow from the pump through the single inlet of the flow dividing apparatus. The pump will generate a flow stream from each of the two or more outlets and perform work that, in the absence of the flow dividing apparatus, would have to be performed by two or more pumps. The reduction in the number of pumps used necessarily reduces both operating costs and emissions.
