Abstract
The casing of a centrifugal pump which is subjected to pronounced external stresses is secured to a foundation or to a base plate by one or more rings which surround the casing and receive stresses therefrom. Each ring has lugs which transmit the stresses to the support; one surface of each such lug can be located in a plane which includes the axis of the pump casing and each of these surfaces abuts a complementary surface of the support. If the casing is surrounded by two rings, each ring is located at a different axial end of the casing. One of the rings can be shrunk onto the casing, and the other ring then allows the casing to move angularly and/or axially therein or therewith but relative to the foundation or base plate so as to compensate for dimensional changes in response to temperature changes. Instead of being shrunk onto the casing, the one ring can be secured thereto by one or more keys, wedges and/or pins.
