Abstract

A centrifugal pump comprising a cylindrical body (10) which contains a plurality of stages, the pump being obtained from the combination of the cylindrical body (10) formed by a segment of metal pipe, of diffusers (15) and impellers (16) obtained by blanking, stamping and welding metal plate, and of heads (12) obtained by precision casting.
