The Test Station offers a closed test circuit with a pressure tank equipped with a compressor and a pump for adjusting the pump suction pressure (-9m ; +25m). It allows the measurement of performance parameters in pump or turbine mode, determination of cavitation properties of pumps, measurement of dynamic quantities or observation of the flow in the pump interior.
