ABSTRACT:
A quick priming centrifugal pump for use in automatic washers and the like wherein the size of the vortex which is formed in the pump and which inhibits priming, is reduced in volume, therefore permitting the pump to be a quick priming pump. The pump includes an extended pump impeller hub which reduces the axial length of the vortex which can be formed in the pump inlet. Additionally, a bevelled cut on the end of the inlet further reduces the axial length of the vortex. Lastly, a projecting rib formed on the inner surface of the inlet reduces the diameter of the vortex which may be formed.
