In many manufacture fields, such as foods, medical supplies, cosmetics, lubricants and paints of present in used, a Shear pump successively takes advantage of such cavitation effects as a large amount of cavitation bubbles and the associated impulsive high shock pressures, to the mixing, to the stirring and to the emulsion. In this study, to estimate the behavior of the cavitation effects in the shear pump, we precisely evaluate the performance. Although the performance of the shear pump, that is the total head Hp, the shaft power Ps, the pump efficiency η — the flow rate Q curves, is very similar to those of the centrifugal pump tested in tap water, they are much different from that in higher viscosity solutions of 500 cP.
