Fluid machineries for fluid food have been used in wide variety of field i.e. transportation, the filling, and improvement of the quality of fluid food. As for the research on them, because the targeted fluid is different from air and water, the flow field is very complex and unclarification. Therefore, the design based on internal flow conditions is not so performed at present, and it chiefly pays attention to the transit performance and the product development is done. This research targets the food transportation pump. It aims at the improvement of the transit performance considering the quality retention of the food fluid. In this research, turbo-pump having small number of blade number was used to decrease shear loss and keep wide flow passage. Performances and internal flow conditions of turbo-pump using low viscous fluid were clarified by experimental and numerical analysis results. In addition, the design method based on the internal flow is considered.
