Abstract: The invention relates to an applicator (1) for treating the teats of milking animals, comprising a handgrip body (2), a cup (3) and connecting means (5) for the connection to a line supplying a pressurized gas, further comprising connecting means (6) for the connection to a line providing a liquid detergent and/or a disinfectant product, and delivery means (7, 8, 9, 10) adapted to fill said cup (3) with a foam produced by mixing said product with said gas. A plant for the use of a plurality of such applicators (1) is also discloses, featuring a product line (30) and a compressed air line (31) fitted with joints (34) for the connecting means (5, 6) of the applicators (1).

Abstract: A magnet pump with bi-directional axial self-alignment comprises an inner chamber (12), provided with a suction duct (13) and a delivery duct (14); an impeller (25) located in said chamber (12) in a rotatably and axially movable manner, and having, a front portion (26) oriented towards the suction duct (13); a driven rotor (31) integral with the motor spindle (51), located outside said chamber (12) and bearing magnets (34) cooperating with as many driven magnets (35) facing the same, located in the rear portion (27) of impeller (25), and a magnet (41) fixed in the inside of said chamber (12) and cooperating with a second magnet (42), incorporated in said impeller (25) so as to realize a linear magnetic coupling.
