Abstract
A submersible pump comprises a rotational assembly and a rotational assembly housing. The rotational assembly has a plurality of in-line flow inducing sections. A centerline longitudinal axis of each of the flow inducing sections extends colinearly with a rotational axis of the rotational assembly. A downstream end portion of a flow pressurizing section is engaged with an upstream end portion of a rotational flow amplification section. A downstream end portion of the rotational flow amplification section is engaged with an upstream end portion of a flow outlet section. The rotational assembly housing has an interior space extending along a centerline axis of the rotational assembly housing. The rotational assembly is disposed within the interior space of the rotational assembly housing. The rotational assembly and the rotational assembly are jointly configured for causing the rotational axis to extend colinearly with the centerline longitudinal axis of the rotational assembly housing.
