Numerical Prediction of a Lifting Pump For Deep-sea Mining

The performance of a lifting pump is numerically predicted using commercial code. This four-stage lifting pump is designed for deep-sea mining. Pressure distribution, head chart, and streamlines are calculated in this paper. The number of blades of impeller in one-stage is 5 and the number of guide vanes is 6. Solid-liquid flow in a pump is analyzed and compared with the result of clean water.
