ABSTRACT:
A centrifugal pump having a two member casing in which a first member with a circular peripheral inner wall incorporates a discharge branch and the other member is shaped in such a way as to determine the shape of the volute of the pump when the two members are brought together. The first casing member has a flange extending transversely from the peripheral wall. The second casing has a flat surface for abutment against the flange to seal the two members. The second casing member has a centrally raised section in which the radius of the section varies circumferentially so that the flow area of the volute of the pump varies circumferentially within the pump.
