ABSTRACT:
A multistage pump or compressor includes a series of axial flow stages. Each stage comprises an impeller for imparting whirl to the pumped fluid in one direction and a stator including vanes for imparting whirl to the pumped fluid in the opposite direction. The stator vanes define flow passages configured such that the fluid flows through the passages at substantially constant absolute velocity. The average ratio of stage axial length to impeller diameter for each axial flow stage is less than 0.4.
