Abstract
A fluid pump may include an electric motor having an output shaft driven for rotation about an axis and a pump assembly coupled to the output shaft. The pump assembly has a first cap and a second cap with at least one pumping channel defined between the first and second caps, and an impeller between the first and second caps. The impeller is driven for rotation by the output shaft of the motor and includes a plurality of vanes in communication with the at least one pumping channel. Each vane has a root segment and a tip segment and a line from a base of the root segment to an outer edge of the tip segment trails a line extending from the axis of rotation to the base of the root segment by an angle of between 0° and 30° relative to the direction of rotation of the impeller.
