A vortex pump is provided wherein an impeller is of an open type and plural blades are grouped into two or more groups, the axial width of each group of blades being different from the others so that the blades belonging to a certain group extend into a vortex chamber so as to directly drive the liquid in the vortex chamber while relatively large pieces of foreign matter are permitted to pass through the pump.
