A gerotor pump includes an inner ring and an outer ring. The inner ring is rotateable about an axis, where the inner ring has an outer diameter contact surface. The outer ring has an inner diameter contact surface that defines a central opening. The central opening receives the inner ring, and a portion of the inner diameter contact surface engages a portion of the outer diameter contact surface of the inner ring. A motor including a rotor and a stator that surrounds the rotor is included. The rotor surrounds the outer ring and exerts a driving force on the outer ring such that the outer ring rotates about the inner ring. The inner diameter contact surface of the outer ring and the outer diameter contact surface of the inner ring create a plurality of chambers. Rotation between the inner ring and the outer ring expand and contract the chambers to expel fluid from the gerotor pump.
