Provided is a vacuum self priming pump. The pump includes an actuating member that is installed in an outlet by a hinge shaft to be capable of rotating and configured to be quickly opened by water pressure when water is discharged through the outlet, an arm that extends from the actuating member to an external side over the outlet, a clutch unit that is movably formed in a length direction of a rotational shaft of a motor to selectively transfer power to an eccentric wheel to free-rotate the eccentric wheel on the rotational shaft, and a transferring unit that is installed between the arm and the clutch unit to cut off the power from the clutch unit to the eccentric wheel when the arm moves.
