In the papers already published the present writers suggested that the characteristics of a regenerative pump might be improved if the influences of the suction port could be removed. In this note and in the next one the developments of the study in the line, both theoretical and experimental, are reported with some results which verify the above-mentioned idea. In this note the cause of the influences of the suction port is studied : by proving that the influences of the immature development of the velocity profile are not sensitive and that the turbulence is not yet sufficiently developed in the pumping passage near the port, it is clarified that the uinsufficient turbulence is the source of those influences. In order to eliminate these effects, the position of the entry of the pumping passage should be moved toward down-stream. By doing so, the fluid is disturbed by the impeller and the turbulence is thus fully developed.
