PROBLEM TO BE SOLVED: To enlarge a conventional vacuum piston pump and enhance its accuracy; and provide a large vacuum pump for sucking and discharging a power- generating discharge water through a lifting pipe without causing losses. SOLUTION: To pump up a power-generating discharge water at a rate of 5 to 10 t/sec, the lifting pipe is filled with water by means of a siphon pipe 6 and the piston movement of a vacuum piston pump 2 is converted into vertical movement by gravitational movement based on the principle of levers. To obtain a maximum kinetic speed with minimal energy, hydraulic cylinders 13 pointed in different directions are attached to opposite ends of a lever and weights at the opposite ends are controlled to achieve the desired speed and a smooth suction and discharge of the vacuum piston pump.
