Claim 18:
19. A method of assembling a centrifugal pump assembly, comprising:
installing a plurality of pump stages onto a drive shaft, wherein each pump stage comprises an impeller coupled to the drive shaft and a diffuser, wherein each diffuser comprises a first plurality of vanes each having a first axial length and a second plurality of vanes each disposed between a pair of vanes of the first plurality of vanes and each having a second axial length, wherein the second axial length is between three quarters (¾) of the first axial length and one quarter (¼) of the first axial length, wherein the first axial length and the second axial length extend in the direction of a centerline axis of symmetry of the diffuser and wherein the centerline axis of symmetry of the diffuser is coincident with a centerline axis of the centrifugal pump assembly;
installing a housing over the plurality of pump stages, wherein the housing retains each of the diffusers;
coupling a base to a downhole end of the centrifugal pump assembly; and
coupling a pump discharge to an uphole end of the centrifugal pump assembly.
