PROBLEM TO BE SOLVED: To provide a high pressure gas-liquid pumping device capable of rotating at a low speed, providing high pressure power, reducing the noise vibration, reducing the energy loss, simplifying the structure and operation with the low cost, free from the environmental destruction and being used in various purposes. SOLUTION: In this pumping device, a plurality of pumps 1-1, 1-2,... 1-p for forcibly feeding the gas-liquid through a common pipe, are connected in series by means of a gas-liquid force feed pipe 2, a second and following pumps 1-2,... 1-p are mounted in a sealed container 3 and provided with liquid reducers 4 so that each pump can cope with the pressure, a gas-liquid amount and a gas-liquid ratio, the gas-liquid is injected into the first pump 1-1 with a desired ratio, the pumps are simultaneously rotated by 1-100 times/min, the pressure force is successively accumulated, the excess liquid in the sealed container 3, of the second and following pumps is reduced by the liquid reducer 4, and the maximum pressure is force fed to the external which needs the pressure, through the last gas-liquid force feed pipe 5 from the last pump 1-p.
