Pump suction sump is an important part of pump station and its flow situations influence the performance of pumping system greatly. In this paper, the pump suction sump with particular structure is designed to improve the flow situations near the pump intake. In order to validate the effect of the improved structure, three experiments were carried out on both the original and improved structures, including the experiment of critical flow rate for air entrainment, the experiment of free water surface height measurement, and 3D PIV experiments at the pump sump. The results of the experiments show that water depth and inlet flow velocity influence the flow situations greatly. The results also show that the improved structure is useful to improve flow situations in pump suction sump.
