A magnetic spinner device using an impeller system to disperse heat and stir contents there-above is disclosed herein. A motor turning the impeller is offset from a center line extending vertically through the device. The impeller, however, is centered with fan blades pushing air downwards as heat rises from a heat source placed there-below, such as between legs which support the impeller and bowl of the device, the bowl being used to hold a flask and/or substances to be heated. In this manner, the electric parts (the motor) and spared the brunt of the heat by being off-center while the heat rises upwards. The simplification of parts leaves less points of potential failure compared to the prior art as does the movement of electric parts away from being above a heat source.

The invention relates to a pump assembly, especially of a mechanical seal assembly, for supplying a fluid, especially to a mechanical seal (2a, 2b), comprising exactly one drive (11) comprising a drive shaft (24), a first axial pump (21), which conveys the fluid in the axial direction (X-X) of the drive shaft, a second axial pump (22), which conveys the fluid in the axial direction of the drive shaft, and a radial pump (23), which conveys the fluid in the radial direction (R) of the drive shaft, wherein the first axial pump (21) and the second axial pump (22) are arranged in front of the radial pump (23) in the flow-through direction (B) of the fluid across the pump assembly, and wherein the drive (11) simultaneously drives the first axial pump (21), the second axial pump (22) and the radial pump (23).

Provided is a fluid pump assembly. The pump has a pair of housings magnetically coupled to each other. The first housing contains a drive motor and a magnetic assembly. The second housing contains a magnetic assembly and a blade for imparting movement to a fluid. As the first magnetic assembly is rotated by the drive motor, the magnetic connection to the assembly in the second housing causes the second magnet to rotate, driving the blade.

An electric machine is configured to be positioned within a wellbore. The electric machine enclosed within a housing isolates the electric machine from fluids within the wellbore. A first lubrication circuit includes a lubrication reservoir within the housing. The lubrication reservoir is fluidically connected to the electric machine. The first lubrication circuit is configured to provide lubrication to a bearing within the electric machine. A fluid rotor is configured to move or be moved by a fluid within the wellbore. A magnetic coupling couples the fluid rotor and a rotor of the electric machine to rotate in unison. A second lubrication circuit is configured to provide lubrication to a bearing supporting the fluid rotor.

A magnetic pump includes a front casing including: a shaft supporting body that supports a leading end of a supporting shaft; and a plurality of supporting legs that extends toward an inner wall of a suction port from the shaft supporting body, and that supports the shaft supporting body in the suction port. In the magnetic pump, a leading end of the shaft supporting body is positioned further toward the inlet side of the suction port than a connecting section between the inner wall of the suction port and the supporting leg.

A cooling unit comprising a coolant fluid pathway in which there is (a) a centrifugal pump which serves to pump coolant fluid along the pathway when the unit is in use, and (b) a heat exchanger which serves to cool the coolant fluid which is thus pumped along the pathway. The pump has a rotor constituted by a magnetically contactlessly driven impeller which is provided with at last one magnet and which is enclosed within a housing, and stator outside the housing and provided with at least one electromagnet operable to act on the said at least one magnet to rotate the impeller.

A disposable fluid pump is provided with a housing including first and second faces, with a sidewall extending between the first and second faces. The housing defines a chamber, with an inlet and an outlet in fluid communication with the chamber. An impeller is rotatably mounted within the chamber and includes a plurality of flexible vanes. Such a pump may be incorporated into a disposable fluid flow circuit that is adapted to be mounted on a durable hardware for processing a fluid. In such a fluid flow circuit, the fluid pump may be integrated into a cassette of the circuit or, alternatively, the inlet and outlet of the fluid pump may be directly connected to fluid flow conduits of the circuit.
