A centrifugal pump that includes an inlet chamber having a distal end portion and an opposing proximal end portion with a longitudinal axis spanning therebetween. Further included in the centrifugal pump is a plenum chamber having an inlet end portion and an outlet end portion, the inlet end portion is in fluid communication with the inlet chamber proximal end portion, the outlet end portion having an aperture that is about a radial axis that extends radially a distance outward from the longitudinal axis. Wherein operationally for the centrifugal pump the inlet chamber and the inlet and plenum chambers are rotated about the longitudinal axis wherein a fluid is drawn through the distal end portion toward the proximal end portion and ultimately discharged therethrough the aperture.

A pump-fan assembly of an air modification device may include a fan, a pump and a disk. The fan may include a central hub disposed on a top surface of the disk, and a plurality of blades extending from the hub towards an outer circumferential edge of the disk. The pump may include a hollow pump body defining an inner tubular passage between an inlet end and a discharge end. An impeller may be arranged at the inlet end and an outlet port may be arranged at the discharge end. The pump and the fan may be coupled at an interface between the discharge end of the pump body and a bottom surface of the disk. The outlet port may be disposed in the interface and arranged to guide a stream of pumped liquid along the bottom surface of the disk. The disk may define a liquid barrier.

A pet water fountain is described comprising a bowl for holding an aqueous drinking fluid. The pet water fountain includes a housing configured to cover a portion of the bowl and have a fluid reservoir. The pet water fountain includes a rotatable cone positioned within the housing, the cone tapering outwardly from a bottom end to a top end, the bone bottom end having a fluid inlet to allow the passage of fluid from the bowl through the inlet and into the interior of the conde, the cone top end being in fluid communication with the housing fluid reservoir. The pet water fountain includes a filter ring coupled to the cone top end, the filter ring having an exterior housing and a filter media positioned within the exterior housing, and an electric motor coupled to the rotatable cone for rotatably driving the rotatable cone.

A liquid transport apparatus includes: a U-shaped vessel for storing the liquid; an inverse conically shaped body which is hollow and has an opening part of an upper end and an opening part of a lower end; and a rotating disk driving motor part for rotating the inverse conically shaped body on an axis extending along a substantially vertical direction. The opening part of the lower end of the inverse conically shaped body is immersed in the liquid stored in the U-shaped vessel. In the liquid transport apparatus, an overflow opening part for keeping constant a distance between the opening part of the lower end of the inverse conically shaped body and a surface of the liquid stored in the U-shaped vessel is formed.
