<p>Mixer apparatus including a motor (26) and transmission drive for an impeller, together with associated shafts (20), impellers (24) and a bearing and seal assembly. The apparatus is supported on a tank (10). The support is provided by a machine base (36) having connected beams (42,44) on which the motor (26) and the transmission are located. The impeller shaft (20) and shaft extensions thereof are disposed in telescoping relationship with the transmission, aligned along the same axis. The machine base (36) is parallel to the foundation and is supported on vertical columns (160,162,164,166) which depend from one end of the base and from opposite ends of a cross beam (50) at the other end of the machine base. The cylinders lift the impeller, moving it upward through the transmission so as to enable detachment of the impeller shaft from the seal unit to facilitate seal replacement. <IMAGE></p> |
