<p>The metal plate stator case (1), for radial centrifugal pumps, includes a main body (2), a diffusion volute (10), an axial suction inlet (3) and a radial discharge outlet (4) at the output of the diffusion volute. The volute is constituted by a circumferential channel (11) which is defined in the lateral wall of the main body and has a radial transverse cross section which increases uniformly toward the output of the volute. At least one portion of the channel has, in transverse cross section, a substantially constant radial depth and a uniformly increasing axial width. <IMAGE></p> |
