Abstract: The geometrical parameters of
impeller or volute casing (including guide vane of multistage
pump) have a great effect on pump characteristics, but
ultimately, the pump characteristics are determined by the
geometrical parameters of impeller and volute casing
cooperatively. In this essay, the effect of impeller and volute
casing on pump characteristics will be studied quantitatively
from the angle of optimal matching of them.
