In the 2nd and 3rd reports the author presented already some theoretical conclusions on the sealing performance of a viscous pump. To certify those conclusions experimentally, he prepared a set of testing apparatus and 20 rotors with various shapas of the screw groove. Consequently such experimental results show a good agreement with the previous theory, namely a) The pump lift is proportional to N, L and ν, and inversely to δ〓 respectively. b) The theoretical results for the coefficient of sealing performance Sis verified experimentally. c) The theoretical comparison of various shapes of the groove is also ascertained to be correct by these experiments. d) So far as the sealing action is concerned, the multi-threaded rotors behave in the same manner as a single-threaded one. e) All theoretical results are confirmed experimentally not only regarding a "shaft" screw-type viscous pump, but also a "cylinder" one.
