Located in Höpfingen, Germany, this 80+ year old company specializes in Archimedean screw pumps for high flow, low head applications. Many are used in flood control or at the headworks of wastewater treatment plants. As energy costs increase, Kuhn has been able to take their conventional design and reverse the flow, thus making it a hydropower unit for power generation. Both of these designs carry high efficiency’s and are supported by a manufacturing facility with years of experience in the design and fabrication of these units. These units can be a great source of green energy and GPM has a long history of success with Archimedean screws.
