Abstract

The pump according to the invention comprises an electric motor, a pumping unit driven by the electric motor, and a casing (21) for supporting said motor and unit, this latter comprising a housing (4) in which an impeller (5) is rotatable for rotation by a shaft (17) driven by the electric motor the pump is characterised in that said pumping unit comprises for the impeller an annular support element (13) rigid with said housing and provided with at least one cylindrical support surface (15) arranged to engage with a corresponding cylindrical surface (14) of said impeller in order to support the rotating impeller in the housing, the impeller and the end of said shaft being provided with insertion-joint means (18, 19) arranged to make said shaft torsionally rigid with the impeller.
