ABSTRACT:
A turbopump or the like operating machine driven by a motor includes a casing for the motor having, at one end, a supporting flange for at least one first bearing of the motor shaft and, at the other end, a structure for coupling with a casing of the turbopump. The coupling structure comprises a single coupling flange, which includes a first supporting structure for a fixed sealing element interacting with a movable sealing element associated with the motor shaft and a second supporting structure for at least one second motor shaft bearing. Such first and second supporting structures are rigidly connected to the coupling flange proximate to a central portion thereof and at adjacent positions along the motor shaft.
