A piston pump, perfected, characterized in that its cylinder is formed with a tube, which superiorly carries an annular element for guiding the piston rod; laterally it presents a tubular branch for the liquid outlet and to connect, where appropriate, with the impulsion tube, and that another tubular element is attached at its lower end, which at its lower end has a flange with its lower edge in discontinuous relief to connect and hold elastically and externally to a suction tube and that extends internally in tubular form, of smaller external diameter than the internal one of the body of the pump, closed superiorly and with a cut inclined to bevel curved, forming an elastic tongue and flexible, which opening and closing due to the relative pressures of the liquid on both sides of the tongue acts as a foot valve, that is, for intake and retention.
