ABSTRACT:
An outer tubular member is adapted to be connected at one end with the wall of a pressure vessel, such as a reactor, and an inner tubular member is rigidly connected with and extends coaxially through the outer tubular member. A portion of the inner tubular member extends beyond the outer tubular member into the interior of the pressure vessel, and a pump shaft extends through the inner tubular member. A radial bearing for the pump shaft is located in the aforementioned portion of the inner tubular member and a pump wheel is connected with the pump shaft within the pressure vessel. A pump shaft seal is located in the inner tubular member within the confines of the outer tubular member, and arrangements are provided for sealingly connecting the inner and outer tubular members with one another, and for carrying exteriorly of the pressure vessel an additional bearing.
