ABSTRACT:
An agitator shaft for revolving attached blades within a fluid containing tank rotates in support bearings free of any attachment to the tank. A shaft mounted housed seal unit exteriorly of the tank comprises a packing gland and a fitting connected by a flexible tubing with the fitting having a bore and the tank having a complementary opening each substantially larger than the diameter of the shaft. The shaft extends axially through the fitting and opening into the tank and the fitting is secured in the opening. The flexible tubing is designed to absorb torque from the seal unit and such unit permits the shaft to be mounted with equal facility and efficiency on tanks of plastic, rubber or metal and materially reduces shaft alignment problems.
