A fluid mixer comprising a tank designed to contain the fluid to be mixed, a rotary shaft (1) that goes through a hole (22) obtained on the wall (2) of the tank, generating a channel (23) in which the fluid enters from the tank towards a chamber (24) outside the tank, in which the shaft (1) rotates and a seal unit designed to prevent the fluid from seeping out of the chamber (24) is disclosed. The said seal unit comprises a first seal ring (6A) mounted on the rotary shaft (1) and a second seal ring (6B) mounted on a support flange (4) fixed to the wall (2) of the tank, in such a way that the first seal ring (6A) slides in close contact with the second seal ring (6B) preventing the passage of fluid outside the chamber (24). |
