• In the previous paper, it has been shown that the pump lift or the sealing pressure is proportional to the viscosity of the working fluid. We have therefore carried out some experiments, using greases of viscosity higher than that of liquid oils. A summary of the results is as follows ; a) The sealing pressure for the grease is proportional to the rotor speed (N) and the coefficient of sealing performance (S), as shown in the previous papers for oils. b) When using some greases, the sealing pressure is about 30 to 70 times that for oils. c) The filling state of greases in grooves of rotating shaft is considerably varied with the kinds of greases, so that we must select the suitable depth of groove. d) To keep the viscosity of the sealing substance at a higher value, it is extremely important to cool the sealing apparatus.
