Abstract The influences of geometrical parameters on low specific pump head should be emphasized on comprehensive influence.The comprehensive influence of geometrical parameters on low specific speed pump head is studied by using grey theory,the influence ordering of these parameters also obtained after a lot of calculation in this paper.The calculating result showed that impeller outlet diameter D2 effects on the head largest of these parameters,vane outlet angle β2 smallest,inlet diameter D1,outlet width b2,vane number Z and vane length ratio R were between them successively.This method had important practical significance for research other project programs.
