A blood pump system includes a pump housing and an impeller for rotating in a pump chamber within the housing. The impeller has a first side and a second side opposite the first side. The system includes a stator having drive coils for applying a torque to the impeller and at least one bearing mechanism for suspending the impeller within the pump chamber. The system includes a position control mechanism for moving the impeller in an axial direction within the pump chamber to adjust a size of a first gap and a size of a second gap, thereby controlling a washout rate at each of the first gap and the second gap. The first gap is defined by a distance between the first side and the housing and the second gap is defined by a distance between the second side and the pump housing.

A fluid pump includes a pump element in communication with an inlet and an outlet. Rotation of the pump element generates a suction at the inlet and pressure at the outlet. The suction and pressure cooperate to move a fluid through a fluid path. An accessory fluid path is in communication with the inlet and outlet. The accessory fluid path includes a thermistor in communication with the accessory fluid path. The thermistor monitors a temperature of the fluid within the accessory fluid path.

An electric water pump provided with a housing that includes a cover. The cover may extend from the sidewall and may be fixed to the volute. The cover may include a main portion, a first protrusion, extending from a first side of the main portion towards the impeller, and a second protrusion extending from a second side of the main portion, opposite the first side, towards the base member. The first and second protrusions may define a first aperture. The second protrusion may define a second aperture that may form a first communication passage. The first communication passage may be configured to receive a portion of the first flow of fluid from a first space, disposed between the impeller and the cover, and expel the same to towards the base member.

A heat dissipation module includes a main vapor chamber, at least one auxiliary vapor chamber, a main heat dissipation fin set and at least one auxiliary heat dissipation fin set. The auxiliary vapor chamber is in fluid communication with the main vapor chamber, the main heat dissipation fin set is installed on the main vapor chamber, the auxiliary heat dissipation fin set is connected to the auxiliary vapor chamber, and the auxiliary vapor chamber is arranged between the main heat dissipation fin set and the auxiliary heat dissipation fin set.

Disclosed is a rotary pump including a magnetic rotor arranged in a pump housing and having a magnetic rotor plane, which rotor is operatively connected to a drive for conveying a fluid. The drive is a bearingless motor having a stator configured as a bearing stator and drive stator and having a magnetic stator plane, wherein the stator bears a drive coil and a bearing coil lying in the stator plane and/or a drive bearing coil. The rotor is magnetically contactlessly journalled within the stator, wherein an axial height (H) of the rotor is smaller than or equal to half a diameter (D) of the rotor so that the rotor is passively magnetically stabilized by reluctance forces with respect to the magnetic stator plane both against axial displacement and against a tilt from an equilibrium position.

An electric motor vehicle-axial-flow liquid pump which is designed as an internal rotor pump. The electric motor vehicle-axial-flow liquid pump includes a pump housing with an axial inlet opening for admitting a liquid and an axial outlet opening for discharging the liquid, and an electric motor arranged in the pump housing. The electric motor includes a motor stator with at least one external stator coil, a can formed radially inside the at least one external stator coil, and a rotor body which is permanently magnetized and which is provided as an axial-flow impeller rotatably arranged inside the can. The rotor body has an axis of rotation and at least one blade which pumps the liquid from the inlet opening to the outlet opening along the axis of rotation.

A cardiac pump having a turbine with internal blades, includes a pump designed to circulate a fluid, including a housing, and a turbine which is arranged in the housing and is designed to move rotationally relative to the housing. The turbine includes a body designed to move rotationally, a hollow central part which extends through the body from one side to the other and is intended to allow the fluid to pass through the turbine, and at least one blade that is positioned on the inner wall of the body, in the hollow central part, and is designed to circulate the fluid.

A stator for a downhole-type motor includes a housing. The housing includes a sleeve. The sleeve includes a first layer, a second layer, and a third layer. The first layer is erosion-resistant. The second layer is corrosion-resistant. The third layer can provide structural support. The stator includes a motor stack. The stator can be used to drive a rotor disposed within an inner bore of the housing.
