PURPOSE: A fluid transfer pump is provided to increase portability of the pump and allow the pump to be easily installed, while achieving a high efficiency of fluid transfer operation. CONSTITUTION: A fluid transfer pump(1) comprises a compressor(3) for allowing a plurality of compression pistons(2,2a) to reciprocate within cylinders(12,13) by a power or manual operation so as to transfer fluid; suction cylinders(5,5a) connected to cylinders(12,13) in an air-tight manner and to a connection pipe(8), respectively; and a discharge pipe(6) for discharging the fluid sucked through suction cylinders(5,5a). Each of suction cylinders has stopper rings(19) formed at the upper and lower portion of the suction cylinder so as to allow a plunger(4) to reciprocate within the suction cylinder. Each of suction cylinders has an inlet hole(16) with a check valve(15) which opens toward the inlet direction, and an outlet hole(18) with a check valve(17) which opens toward the outlet direction. The outlet hole is communicated to the discharge pipe.
