The invention relates to the machine building industry and can be used for reverse-running pulsation-free high-pressure pumps. The aim of the invention is to improve the operating characteristics of pumps of a similar variety (and the manufacturability thereof). The inventive pump comprises a rotor with orifices and at least two displacers arranged therein, a working chamber, a barrier separating the increasing area from the decreasing area. The working chamber is formed by surfaces of an annular groove embodied in the end of the rotor in such a way that the inner surfaces thereof confine the working chamber in a radial direction and slide into contact with the barrier's surfaces. The orifices of the rotor containing the displacers are oriented in an axial direction and open out onto the annular groove in such a way that the continuations thereof form pockets on the inner surfaces of the groove, thereby confining the working area in the radial direction.
