Manual pump for transferring liquids, characterized essentially by a body of revolution, segmented configuration and laminar structure, prolonged in a zone also segmented, flexible in axial and elastic direction, with its segments of higher height, associating a lower embouchure from the first body to a support for the intake valve and to the upper mouth of the suction tube, preferably flexible, while the head of the second segmented body receives a bell-shaped part and a supporting tubular top, in its lower part, contiguous at the head of the elastic body, of the tubular support of the liquid outlet valve, while the upper part of the tubular element receives the coupling of the outlet tube, which has its inner end closed and provided with a plurality of holes in the surface lateral, with flexible prolongation and free embouchure for the exit of the transvased liquid.
