In the foregoing paper the cause of the influences of the suction port was studied and it was concluded that those influences came from the immature development of the turbulence in the pumping passage near the suction port. In order to eliminate these effects, the position of the entry of the pumping passage should be moved toward down-stream. In the present paper it is deseribed that the suction port of a pump is reformed into three kinds of forms and their characteristics are compared with each other. It is shown that a pump modified in a suitable manner has much better characteristics than an old type has : the maximum efficiency of the reformed pump is higer by about 9% and its suction-capacity is much larger than that of the old type. These results verify the idea mentioned in the foregoing paper.
