The present invention is directed to a molten metal pump comprising an elongated pumping chamber tube with a base end and an open top end. A shaft extends into the tube and rotates an impeller therein, the impeller rotates proximate the base end. The tube has a diameter at least 1.1 times the diameter of the impeller. The pumping chamber tube preferably has a length at least three times the height of the impeller. The base end includes an inlet and the top end includes a tangential outlet. Rotation of the impeller draws molten metal into the pumping chamber and creates a rotating equilibrium vortex that rises up the walls of the pumping chamber. The rotating vortex adjacent the top end exists the device cia the tangential outlet.

Disclosed is a motor and a drain pump including the same. The motor includes a rotor, a rotation shaft positioned through a center of the rotor, and a shaft fixing member for supporting the rotor and the rotation shaft, in which the shaft fixing member and the rotor include a fixing device provided in a direction that intersects a rotation direction of the rotation shaft to prevent the rotation shaft from being idle.

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 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 cone bottom end having a fluid inlet to allow the passage of fluid from the bowl through the inlet and into the interior of the cone, 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 filtering media positioned within the exterior housing, and an electric motor coupled to the rotatable cone for rotatably driving the rotatable cone.

An intelligent control clogging-free water-cooled multifunctional pump includes a housing, a water-through tank, a motor, an axial flow style cover plate, a flexible rubber conical impeller, a double-channel conical diffuser, a filter and an intelligent water level controller. The motor is placed inside the housing. The motor is provided with a control board. The water-through tank is placed under the housing. The flexible rubber conical impeller is coaxially connected to the motor. The axial flow style cover plate is placed at the bottom of the water-through tank. The double-channel conical diffuser is disposed under the cover plate and the conical pattern of the flexible rubber impeller is consistent with the conical pattern of the double-channel conical diffuser.

A liquid atomization device includes: an inlet; an outlet; and a liquid atomization chamber. The liquid atomization chamber is provided in an air passage between the inlet and the outlet. The liquid atomization chamber includes a rotary shaft, a pumping pipe, a collision wall, a reservoir, and a drain port. The rotary shaft is rotated by a rotary motor and is disposed in the vertical direction. The pumping pipe includes a lower portion having a pumping port and an upper portion fixed to the rotary shaft, and is rotated in coordination with rotation of the rotary shaft to pump up water through the pumping port and centrifugally discharge the water. The pumping pipe generates, inside the pumping pipe, a whirlpool in the water in the reservoir by the rotation, and forms, at the center of the whirlpool, a void providing communication between the pumping port and the drain port.
