Abstract
Fluid-food pump used for the process of food supply is required for keeping high performance, decreasing shear loss and simple maintenance and so on. Although, the influence of the fluid food on pump performance and the ideal design method of the fluid-food pump are not clarified, also the design method based on the internal flow conditions is hardly conducted. In this research, a centrifugal pump having small number of blade and open and semi-open impeller was used to decrease shear loss and keep wide flow passage. In this paper, the pump performance and internal flow conditions including the main shroud clearance of the centrifugal pump using low viscous fluid were clarified by experimental and numerical analysis results.
