Summary:An analytical solution for the pressure drop in the disk pump is obtained. It is shown that the characteristics of a disk pump are determined by five dimensionless parameters instead of nine dimensional ones. Three criteria are considered that limit the parameters of the pump for implementation of the laminar regime of fluid flow in the pump. Analysis of the flow rate-pressure head flow characteristics of pumps in dimensionless comparative coordinates clearly demonstrates the hydrodynamic efficiency of pumps. It is shown that the drop in the pump head often occurs at the stage of transition from the disks to the pump outlet. It is shown that the left-ventricular circulatory support pump developed earlier by the present authors is the most effective of those considered in this article.
