ABSTRACT:
A mixing tank for a liquid is disclosed with a built-in agitator having a shaft extending through an upper wall of the tank for engagement with a drive motor module. For shipping purposes, the shaft opening is sealed against leakage of the liquid by a seal ring which is compressed by a seal clamp between a collar fixedly mounted on the shaft and a fixed member on the upper wall of the tank. When the agitator is operated at a work station to mix the liquid, the seal clamp is released and the agitator shaft is driven by the drive motor module. In order to prevent liquid leakage around the shaft during shaft rotation, a rotor is mounted on the shaft inside the tank and the liquid which migrates up the shaft to the rotor is thrown outwardly thereby.
