The pump group has a mechanical drive having a rotating member mounted in free rotation on the control body for receiving an external action from an external group, a rotating drum integrally connected to the control end, and a control device configurable in an engagement configuration, in which the rotating member and the rotating drum are engaged to rotate together, and a disengagement configuration, in which the rotating member is separate from the rotating drum rotating individually.

Methods and systems are provided for an internal combustion engine assembly comprising a water pump driven by a crankcase venting system. In one example, a method may include adjusting a transmission ratio of a magnetic transmission in response to a temperature of an engine, wherein the magnetic transmission connects a water pump to a crankcase venting system of the engine.

An energy-conserving fluid pump is an apparatus used to transport low viscosity fluids like water and fuel without experiencing cavitation, recirculation, nor motor locking while also conserving energy. The apparatus includes a fluid diffuser, a fluid densifier, a convergent housing, and a strut assembly. The fluid diffuser improves the efficiency of the apparatus by expanding the fluid inflow and maintaining a fluid pressure buildup. The fluid densifier shears the incoming fluid flow from the fluid diffuser and increases the fluid outflow pressure. The convergent housing encloses the fluid diffuser and the fluid densifier while facilitating the outflow of the pressurized fluid without the loss of fluid pressure nor cavitation. In addition, the convergent housing facilitates the transfer of torque to the fluid diffuser for the operation of the apparatus. The strut assembly keeps the fluid densifier stationary while enabling the rotation of the convergent housing and/or the fluid diffuser.

A fluid pump assembly is used in combination with a container having a wall. The pump assembly comprises a first casing disposed outside the container in contact with the wall, a first magnetic assembly mounted to the first casing and operatively associated with a drive motor, a second casing disposed inside the container in contact with the wall, and a second magnetic assembly mounted to the second casing and operatively associated with an propeller. The first magnetic assembly includes a rotatable magnetic drive member drivingly coupled to the drive motor. The magnetic drive member is magnetically coupled to the magnetic driven member through the wall for imparting a rotary driving force of the drive motor to the propeller. Furthermore, the second casing is detachably connected to the second side of the wall of the container solely by magnetic attraction force between the first and second magnetic assemblies.

Apparatus for an electrically powered fluid feature comprises a unit including a fluid pump and a rechargeable power source arranged to provide power to the pump for operation of the fluid feature. The power source may be rechargeable via electrical contacts. The unit may comprise upper and lower housing portions that are separable to allow cleaning, replacement or recycling of components. The unit may be removably installed in a reservoir, which is supported within a container by adjustable supports.

A thermal management module comprises a housing and a drive shaft located within the housing. The housing is provided with a first internal cavity, a partition and a second internal cavity which are arranged in series along the axial direction of the drive shaft. The first internal cavity and the second internal cavity are separated by the partition. The partition is proved with a through-hole through which the drive shaft passes. One end of the drive shaft extends into the first internal cavity. A second internal cavity is used for receiving a drivetrain for rotating the drive shaft.

A gas generating apparatus with separated water pump, comprising a delivery device, an electrolytic device and a water pump. The delivery device accommodates electrolyzed water. The electrolytic device is configured for electrolyzing electrolyzed water to generate hydrogen. The water pump comprises a stirring fan and a drive motor. The stirring fan is configured inside the delivery device to promote the electrolyzed water flowing. The drive motor is coupled to an outer surface of the delivery device and is configured for driving the stirring fan to promote the electrolyzed water flowing. In present invention, the flowing electrolyzed water driven by the separated water pump cools down the electrolytic device, and the drive motor is prevented from corroding by the electrolyzed water and the cooling efficiency of the drive motor is increased. Therefore, the operational safety is improved and the life of the gas generating apparatus with separated water pump is extended.

A pump assembly mounts on a universal adapter having a back end attached to a motor, a receiving area, an outer magnet assembly rotatable around the receiving area by a motor, and a forward mounting plate surrounding the forward receiving area and having mounting features for attachment to the back cover of each of a variety of pump assemblies. The pump assembly includes a casing having an inlet and an outlet. A back cover attached to the casing has mounting features for attachment to the mounting features of the universal adapter. A containment shell includes a cup for positioning in the receiving area. An inner magnet assembly is positioned in the cup is rotatable by magnetic coupling to the outer magnet assembly through the cup. An impeller is rotatable within the casing by the inner magnet assembly to pump fluid from the inlet to the outlet.

A universal pump assembly mounts, interchangeably, on a canned motor or on an adapter having an outer magnet assembly rotated by a motor. The pump assembly has a casing with an inlet and an outlet, and an impeller rotatable within the casing to pump fluid from the inlet to the outlet. The pump assembly can have either a mounting ring for attachment to the canned motor, or a containment shell having a cup with an inner magnet assembly and a mounting ring extending from the cup for attachment to the adapter. Mounting features of the mounting ring may be threaded holes or internally threaded posts as non-limiting examples.

A hybrid coolant pump assembly comprises a housing, a bearing shaft, and an impeller apparatus. The bearing shaft is rotatably supported within an internal cavity of the housing. A first clutch is disposed on the bearing shaft and is operable to drivingly interconnect an input member and the bearing shaft when in an engaged state. The impeller apparatus is positioned about the bearing shaft and configured to pump a fluid. A rotor, disposed within the internal cavity of the housing, extends about the bearing shaft. A stator, disposed within the internal cavity of the housing, extends about the rotor. The rotor rotates relative to the stator and the bearing shaft when the stator is electrically energized. The impeller apparatus is rotatably driven by the bearing shaft when the first clutch is in the engaged state. The impeller apparatus is rotatably driven by the rotor when the stator is electrically energized.
