Characteristics of a nozzle-type fluidic pump, which has two nozzles set up opposite each other, were experimentally investigated. The pump performance is influenced by a pump installation level and a delivery pipe volume. The pump operating region controlled by a driving pressure is restricted by the receiver nozzle inlet cavitation. The discharge and the efficiency of the pump increase as the displacement volume increases in a certain operating range; however, a too large displacement volume produces little effect on the pump performance. As for the structural factors, the following is shown. In the case in which a pair of geometrically similar nozzles is adopted as the pump nozzles, the volumetric efficiency of the pump with small diameter nozzles is higher than that with large ones and the discharge is lower reversely. The pump composed of the almost-same-diameter nozzle pair can attain a higher discharge than that of a different diameter nozzle pair in a high head operation region.
