IMPROVED CASING AND CASING LINERS FOR CENTRIFUGAL PUMPS OF THE VOLUTE TYPE

摘要

A centrifugal pump casing of the volute type having a volute region comprising two circular segments of differing radii adjoining tangentially and a discharge branch leading tangentially away from the segment of greater radius. Liners for the casing are formed in the same manner. Preferably the adjoining circular segments are of common constant cross section.
