Abstract
A fluid pump includes a motor, an inner gear rotor and an outer gear rotor. The inner gear rotor is driven for rotation about an axis by the motor and has a plurality of outwardly extending teeth. The outer gear rotor has a plurality of inwardly extending teeth that are engaged by the teeth of the inner gear rotor so that the outer gear rotor is driven for rotation about a second axis when the inner gear rotor rotates. At least one of the inner gear rotor and the outer gear rotor is formed from a plastic material.
