Abstract
The axial pump makes it possible to deliver a fluid having a double gaseous-liquid phase at high flow rates. It is constituted by a one-piece rotor comprising a hollow shaft (10) onto which are shrunk pulsating systems (12). This rotor is placed within a body (2) constituted by a stack of washers (3) within which are fixed straighteners (14). Each straightener is constituted by two half-straighteners, so as to permit the installation of each straightener around the rotor. Everything is sealed by end flanges on which the rotor is mounted in rotary manner. The pulsating systems (12) can also be machined on the outer surface of the body (10).
