<p>A fluid-ring pump according to the invention for use as a vacuum pump, e.g. for the aspiration of centrifugal pumps, and for use in the transport of mixtures of fluids and gases or solid particles, is of the type where the distance between the internal surface (17) of the pump housing and the rotor (10) varies. Seen in section, the surface is divided into two identical, reverse-image sectors, in relation to which the rotor (10) is disposed in a symmetrical manner. The opposing forces as a result of the diametrically-opposite directed sealing pressures hereby cancel each other out, and the rotor blades (14) can have a greater pitch with a consequent increase in capacity. <IMAGE> <IMAGE></p> |
