1. A pump, comprising:
a material pressurizer including an exterior body, a centralizer tube, and a plurality of helical vanes each extending between the exterior body and the centralizer tube at least partially along a length of the exterior body to jointly define a plurality of helical flow passages, wherein the exterior body includes a divergent section and a convergent section extending from the divergent section, wherein a first portion of the centralizer tube extends at least partially along a length of the divergent section and a second portion of the centralizer tube extends at least partially along a length of the convergent section, wherein the divergent section and the convergent section are attached to each other such that a maximum diameter of the exterior body is located between opposing end portions thereof, wherein a centerline longitudinal axis of the divergent section extends colinearly with a centerline longitudinal axis of the convergent section, and wherein the divergent section and the convergent section are conically-shaped.
