Impeller containing a pair of blades wherein the leading edge of one of the blades is thicker than the leading edge of the other

摘要

An impeller for a submersible radial pump has an impeller disk which is formed with a pair of blades on a side thereof opposite the boss. The leading end of one of the blades is thicker than the leading end of the other blade to reduce the possibility that pieces of fabric or the like will hang up on the blades in operation of the pump.
