A submersible pump-motor assembly for use in dispensing petroleum from petroleum storage tanks. The pump-motor assembly of the present invention enhances the performance characteristics of the pump-motor assembly by providing greater flow area around the motor stator while maintaining the alignment of the assembly's critical pump components. Such enhanced pump performance characteristics provide the petroleum dispensing station manager using such pump-motor assemblies with greater flow rates per dispenser or, when maximum flow rates are capped, potentially greater dispensing capacity.
