ABSTRACT:
A sealing means is disclosed which comprises a support member provided with a groove adapted to receive an annular seal therein which mates with the outer spherical surface of a swivel ball of a tank mixer upon installation thereof. The groove is positioned so that it is disposed between the diametrical section of the ball taken substantially parallel to the tank wall and the tank wall and that the internal pressure of the liquid in the tank urges the seal towards the diametrical section of the ball.
