A submersible pump assembly includes an electric motor (1) and a centrifugal pump, which is driven by the electric motor (1). A rotor (4) formed of plastic or composite material which is manufactured in the extrusion or pultrusion method.

A pump includes a seat unit, a motor unit and a leak detector. The motor unit includes a rotor, an inner case body, an outer case body and a stator. The inner case body has an inner end wall. The outer case body is sleeved on the inner case body and has an outer end wall. The outer end wall cooperates with the inner end wall to define a liquid-receiving space therebetween. The leak detector is disposed on one side of the outer end wall opposite to the liquid-receiving space and includes a sensor for detecting the change of the electrostatic capacity between the liquid-receiving space and the sensor.

A device for the transmission of power using rotating magnetic fields includes a drive shaft with an external magnet, a pump shaft with an internal magnet suited to entrained by the external magnet, a rear tight chamber or containment body for the pump shaft and the internal magnet, the rear body being positioned between the internal magnet and external magnet. The rear body includes at least a glass-shaped casing and one or more probes buried within the thickness of the glass-shaped casing.

Rotary devices having a casing and an inner drive portion of a magnet coupling disposed inside of a rotor assembly are disclosed. The inner drive portion and rotor assembly are disposed within the casing and rotatable about a rotational axis. The rotor assembly includes a bushing between the magnets of the rotor assembly and a stationary canister is sealed to the casing and separates an internal fluid chamber within the casing from the inner driven portion. The stationary canister can be of multi-piece or unitary construction and is held in position by a front portion of the casing.

A method for producing a can formed from a can part and a flange part is provided, the flange part being formed as an annular body and, on a side oriented inward toward an axis of symmetry of the annular body, an interface forming a bearing for the can part. A base and a lateral wall are formed on the can part, and the can part is deep drawn and made into a target geometry with a defined wall thickness by virtue of the lateral wall being flow formed. The lateral wall has a formed interface with a material thickness greater than the wall thickness of the lateral wall, and the flange part is connected to the can part at the interface.

A The hybrid pump includes an impeller, a magnetic drive configured to control rotation of the impeller, a drive shaft combined with the magnetic drive and a motor. The drive shaft rotates in response to rotation of an axis of the motor, the magnetic drive rotates when the drive shaft rotates, the impeller rotates in response to rotation of the magnetic drive, a drive body of the magnetic drive is formed of plastic, and the drive shaft is formed of metal.

A split can for a magnetic coupling includes a cylindrical jacket region and a base region connected to a first end of the jacket region. The jacket region has an inner wall and an outer wall enclosing the inner wall. The inner wall and the outer wall are spaced apart from each other in the radial direction by a gap, with the inner wall being integrally joined to the outer wall by a plurality of webs. The gap may be provided with a control medium which may be monitored to detect changes in one or more characteristics of the control medium indicative of split can leakage.

A magnetic levitation centrifugal pump comprises: an internally hollow body, an inlet connector and an outlet connector for blood. The hollow body comprises a lower element and an upper element which are mutually coupled to each other; a rotor element housed inside the hollow body and provided with a portion made of magnetic material, the rotor element being magnetically commanded in rotation about a relative axis, without contact, by a stator element associable with the hollow body. The upper element has a perimeter flange for coupling and a substantially dome-shaped body projecting from the perimeter flange. The outlet connector is associated with the dome-shaped body and is spaced away from the perimeter flange, between the outlet connector and the perimeter flange being defined an air space inside which mutual tightening device/component can be inserted for the tightening of the upper element with the lower element.

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.
