Claim 17:
18. A submersible pump, comprising:
an impeller having a sidewall that extends around the rotational axis to define an interior space of the impeller, wherein the sidewall includes a plurality of flow-inducing protrusions each extending outwardly away from the interior space of the impeller and extends from adjacent the first end portion of the impeller, wherein each of the flow-inducing protrusions extends from adjacent the first end portion of the impeller to adjacent the second end portion of the impeller, wherein each of the flow-inducing protrusions has a leading edge and a trailing edge relative to the rotational direction, and wherein each of the flow-inducing protrusions has a fluid flow passage extending therethrough along at least a portion of the leading edge thereof;
a rotational flow amplification body having a first end portion thereof engaged with the second end portion of the impeller in a manner that inhibits unrestricted rotational movement therebetween in at least the rotational direction, wherein the rotational flow amplification body has an elongated central passage, wherein a centerline axis of the rotational flow amplification body extends colinearly with the rotational axis, wherein a plurality of vanes extend from an interior surface of the rotational flow amplification body defining the elongated central passage, and wherein each of the vanes extends from adjacent the first end portion of the rotational flow amplification body with an inclination in a direction opposite the rotational direction of the rotational assembly.
