A novel impeller for a regenerative turbine fuel includes a hub and a plurality of V-shaped vanes that project radially outward. The hub defines an aperture into which the shaft of the pump is securable. Each V-shaped vane includes a pair of fin members. Each fin member has an inner sidewall and an outer sidewall. The fin members of each vane are adjoined by their inner sidewalls. From their adjoined inner sidewalls, the fin members of each vane diverge to their respective outer sidewalls. In particular, the fin members of each vane diverge at a prespecified angle relative to a plane that lies normal to the center axis and also bisects the hub. Along at least part of its length, the trailing corner of each outer sidewall of each V-shaped vane is chamfered. The chamfer is made at a predetermined angle relative to the aforementioned plane.
