    摘要: Floating pump comprising:
    flotation means (1) on a liquid medium (A),
    an axial or semi-axial flow pump (2) supported by the flotation means (1) comprising an inlet (3) and an outlet (4), comprising transmission means (5) which comprise a drive shaft (6) and are arranged in fluid communication with said inlet (3) and said outlet (4) of the axial or semi-axial flow pump (2), enabling the establishment of a flow of fluid to be pumped along a longitudinal axis (7) coinciding with the drive shaft (6), which in the working position, a first end (6') of the drive shaft (6), located in proximity to the outlet (4) of the axial or semi-axial flow pump (2), is in the submerged position, while a second end (6") of the drive shaft (6), opposite from the first end (6'), is in the non-submerged position, such that the orientation of the drive shaft (6) is inclined with respect to the surface of the liquid medium (A) whereon the flotation means (1) are located.

    摘要: In at least one embodiment, the liquid circulation system (100) comprises
    - a rotor (1) located within a tank (3),
    - a stator (22) having a plurality of coils (23) outside the tank (3), and
    - an exterior tank wall (30) that is non-magnetic and that is located next to the rotor (1) and between the rotor (1) and the stator (22),
    wherein
    - an axis (R) of rotation of the rotor (1) is in parallel with the exterior tank wall (30),
    - the coils (23) of the stator (22) are arranged along the axis (R) of rotation of the rotor (1) so that the rotor (1) is configured to be rotated by the stator (22) in a touchless manner through the exterior tank wall (30) by means of a varying electromagnetic field driven by the stator (22) to circulate a liquid (4) within the tank (3).
