An electric submersible pump includes a shaft, a motor mechanically coupled to the shaft, and an impeller rotationally coupled to the shaft. The impeller includes a first hub and a first shroud. The first shroud is concentrically disposed about the first hub and has a first axial end and a second axial end. The second axial end is disposed radially outward with respect to the first axial end. A slope of an interior surface of the first shroud proximate the second axial end is within 20 degrees of being parallel to a longitudinal axis of the shaft. The impeller further includes first vanes extending from the first hub to the first shroud. The electric submersible pump further includes a diffuser fluidly coupled to the impeller. The diffuser includes a second hub, a second shroud concentrically disposed about the second hub, and second vanes extending from the second hub to the second shroud.
