Claim 4:
5. The submersible pump of claim 4 wherein:
a closed end portion of the interior space of the flow pressurizing section opposite the downstream end portion thereof has a maximum inside diameter less than a maximum inside diameter of the interior space of the flow pressurizing section at the downstream end portion thereof;
the interior space of the flow pressurizing section at the downstream end portion thereof has a maximum inside diameter the same as a maximum inside diameter of the central passage of the rotational flow amplification section;
the central passage of the rotational flow amplification section has a maximum inside diameter the same as a maximum inside diameter of the central passage of the flow outlet section at the upstream end portion thereof; and
the central passage of the flow outlet section has a cross-sectional area along a length thereof that tapers from the maximum inside diameter at the upstream end portion thereof to a smaller inside diameter at a downstream end portion thereof.
