Abstract

PURPOSE: To accomplish operation ensuring the highest possible efficiency along the characteristics covering from lift to amount of liquid and maintenance of normal pressure feed regardless of variations in inflow of liquid by changing the opening of the valve arranged in the pressure feed passage according to the flow rate of an electric pump on the side of the suction port.
CONSTITUTION: A circulation passage 4 on the side of the drain connects a drain port 2 of an electric pump 1 and a nozzle of a jet pump 6 while a circulation passage 5 on the side of suction port connects a diffuser of the jet pump 6 and a suction port 3 of the electric pump 1. A flow rate detection means 7 is arranged in the circulation passage 5 on the suction port side to detect amount of liquid to be sucked into the electric pump 1. An inflow path 8 is communicated to a suction chamber formed between the nozzle and a throat section of the jet pump 6 and a pressure feed passage 9 is provided branched off from the circulation passage 4 on the discharge port side. A valve 10 is provided in the pressure feed passage 9 to change the opening according to detection value of the flow rate detecting means 7. Amount of liquid to be sent to the recipient system from the pressure feed passage varies with the opening of the valve 10.
