ABSTRACT:
A multistage pump of the type including a jacket, a shaft which is coaxial to the jacket and connected to an electric motor, and active pumping stages rigidly coupled to the shaft; each stage is formed by an impeller with a front ring and by a distribution element facing the ring with the interposition of an annular supporting element shaped like an inverted bowl; the radial-vane impellers and their distribution elements are rigidly coupled to the jacket made of a highly wearproof material, and the impellers are mounted on the shaft and can move axially or float with a preset stroke with respect to the associated bowl-shaped element, whereas at least one annular supporting and sealing element for the impeller is interposed between the front ring of each impeller and the associated bowl-shaped element, is made of a material which is more wearproof than the impellers, and is suitable to withstand the axial thrusts of the various stages and prevent any fluid seepage during pump operation.
