PROBLEM TO BE SOLVED: To provide a pump for a PET bottle, which is screwed into a mouth of the PET bottle and can pour a chilled drink of the PET bottle into a cup in a state of being stored in a refrigerator with the door of the refrigerator kept open. SOLUTION: The pump is constructed as follows. It is equipped with a motor 2 driven by a dry-cell battery 4 connected through a switch 3. A suction pipe 1 is inserted into the mouth Aa of the PET bottle A, and a compact suction cylinder 9 with an inlet port 8 is directly connected to an end of the pipe. A vane wheel 10 is provided inside the suction cylinder 9, which is rotated by a connector 11 capable of transmitting rotation from the motor 2 through a transmission means such as a belt 2a. The pump is further constructed so that the drink B sucked by rotation of the vane wheel 10 through the inlet port 8 provided in the suction cylinder 9 passes through the suction pipe 1, through a passage 12 for almost 90 degrees turn and through a tube-shaped second passage 13 and is discharged from a pour spout 5 connected to its terminal.
