The development of lifting pumps that lift minerals to a mining vessel are one of the vital parts of the commercial mining process. Lifting pumps with a high total head are needed as lifting pumps transfer minerals from the deep sea to a waiting vessel. Accordingly, when we designed the lifting pumps we needed to design the centrifugal pump with a high total head. However, that kind of pump has a small specific speed and it created a small passageway, so they had a problem transferring the minerals. Therefore, we designed a mixed flow pump which has a wider passage way for minerals to flow. Technology to design the pump requires a lot of experience, so more research into how the pump operates is necessary. In this research, I examined the internal flow of the pump by CFD to gather basic information for developing the pump's performance.
