Egger was consulted by multiple engineering firms regarding pumps as turbines (PaT) designed for high flow rates and low heads, aligning with the domain of Kaplan turbines. Through a CFD simulation study using scFlow<\/em> software by Cradle\/Hexagon, we successfully provided solutions with our RPG\/RPP program for elbow propeller pumps.<\/p>\n\n\n

Since March 2024, a DN 350 axial pump (RPG 351) with suction by the elbow has been operating as a turbine on the Birs river in the canton of Basel-Landschaft in Switzerland. It uses a part of the energy lost in the fish pass of an existing hydroelectric power station equipped with a Kaplan turbine. Our pump-turbine enables the plant to produce between 75 and 125 kWh of electrical energy per day.<\/p>\n\n\n\n

Compared with a conventional Kaplan turbine with guide vane, this is a simplified machine in which the elbow replaces the distributor.  This success was achieved without modifying any parts of the axial pumps already in our portfolio. The addition of a frequency converter enables the operating point to be set as close as possible to the PaT\u2019s best efficiency point. Installation is based on a vertical motor axis, with horizontal suction and vertical discharge. This means that only one elbow) needs to be installed in the entire system \u2013 apart from the pump.<\/p>\n\n\n\n
