The purpose of this paper is to suggest the theory of the pulse pump; to introduce the experimental results of the models of the air-operated pulse pump; to estimate the perspective of the development of the pulse pump and its possible applications.The pulse pump is a new-type pump, in which the fluid successively flows out in one direction by means of the pulse effect in the uniflow pipe.The flow pattern is simple in this pump, so that the efficiency of the energy transformation would be higher,and the head range obtained in single stage may be wider as well. In this pump the flow is successive, so that the flow rate would be higher without: any danger of cavitation.We have investigated and made the models of air-operated pulse pump since 1976. The theory suggested have been basically proved by the repeated tests and measurements.
