This document contains recommendations of rigorous pump casing design techniques. A comparison of different design methods is made. The most sophisticated of these is then described in detail. Finally, a list of design checks by which most centrifugal pump casings might be evaluated is given.
Currently, there is not an existing code or standard particular to the design of centrifugal pump casings. Because they must hold internal pressure, it is common for pump users to specify that a pressure vessel code be used as the basis of a manufacturer’s casing design for high pressure pumps.
