In the last report, the sealing performance of a screw-type viscous pump with a screw groove of the rectangular cross-section was treated theoretically. For the purpose of determining the most suitable shape of the screw groove for the sealing performance, the author examine in this paper theoretically a rectangular, semi-circular, fan-shaped and triangular cross-sections respectively. As the results it is seen that in order to obtain the greatest sealing action i.e. the maximum pump lift without delivery, we should select the following shape of the groove ; a) The depth of each screw groove be as shallow as possible. b) The triangular section is the most suitable when the ratio of the depth to the width of the groove remains constant. c) Among the triangular sections it seems that the isosceles one is superior to the others.
