ABSTRACT:
The casing of a centrifugal pump is borne by a second section of a composite frame, and such second section has legs resting on or being embedded in a foundation. A first section of the frame carries a motor for the pump and is carried by the casing. In addition, the two sections of the frame are connected to each other to partially surround and confine the casing against radial expansion in response to increasing internal pressures, and the sections are held against each other so that they are maintained under an initial stress which opposes elastic deformation of the casing. The weight of the motor is transmitted directly to the foundation.
