ABSTRACT:
The invention includes a hydraulic head and contactor shaft assembly combination for attachment to a fluid-containing vessel and motor including: a hydraulic head for removable attachment to one end of a vessel and having a circular aperture in the center; a bearing housing having an open-end and a closed-end. The open-end is fixedly attached to the hydraulic head and the closed-end has a circular aperture. The center axis of the circular aperture in the closed-end of the bearing housing is aligned with the center axis of the circular aperture. There is a single-piece contactor shaft having a first end and a second end. The first end protrudes through the circular aperture in the hydraulic head. A first annular passageway is formed between the single-piece contactor shaft aperture. The first end is configured for removable attachment to a rotatable mixing blade and the second end protrudes through the circular aperture in the closed-end of the bearing housing, forming a second annular passageway between the single-piece contactor shaft aperture in the closed-end of the bearing housing. The second end of the single-piece contactor shaft is configured for removable attachment to a rotatable motor shaft. There is a doughnut-shaped seal for preventing passage of the liquids through the first annular passageway. The doughnut-shaped seal is positioned in the first annular passageway. There is a doughnut-shaped bearing for supporting the single-piece contactor shaft. The doughnut-shaped bearing is positioned in the second annular passageway. A rotatable mixing blade is removably attached to the first end of the single-piece contactor shaft.
