MUMBAI, India, June 20 -- Intellectual Property India has published a patent application (202414091183 A) filed by Levitronix Gmbh, Zurich, on Nov. 22, 2024, for 'a device for changing a pump unit of a centrifugal pump and a centrifugal pump.'
Inventor(s) include Schmid, Alexander; Schneider, Samuel; and Barletta, Natale.
The application for the patent was published on June 20, under issue no. 25/2025.
According to the abstract released by the Intellectual Property India: "A device for changing a pump unit (50) of a centrifugal pump (200) is proposed, which comprises the pump unit (50) and a stator (100) extending in an axial direction (A) from a first axial end (101) to a second axial end (102), wherein a cup-shaped recess (121) is provided at the first axial end (101), into which the pump unit (50) can be inserted, wherein the pump unit (50) comprises a pump housing (52) with a cup (531) which can be inserted into the cup-shaped recess (121) of the stator (100), wherein a rotor (51) for conveying a fluid is arranged in the pump housing (52), which rotor has a magnetically effective core (511), wherein the rotor (51) can be rotated about the axial direction (A), and wherein the stator (100) is designed for a non-contact magnetic drive and a non-contact magnetic levitation of the rotor (51), wherein the rotor (51) is passively magnetically stabilized with respect to the stator at least in axial direction (A). The device comprises an actuating device (6) with which a mechanical force can be exerted on the pump unit (50), wherein the mechanical force acts in the axial direction (A) and is directed in such a way that it separates the pump unit (50) from the stator (100) in axial direction (A). Furthermore, a centrifugal pump for conveying a fluid comprising such a device is proposed."
