    Abstract: A reciprocating fluid pump includes a pump body, a subject fluid chamber, a first plunger located within the subject fluid chamber of the pump body and having a first head portion and a first bellows, the first plunger configured to expand and compress in a reciprocating action to pump the subject fluid through the subject fluid chamber within the pump body, wherein the first head portion and the first bellows have a first cross-sectional dimension, and a second plunger located within the subject fluid chamber of the pump body and having a second head portion and a second bellows, the second plunger configured to expand and compress in a reciprocating action to pump the subject fluid through the subject fluid chamber within the pump body, wherein the second head portion and the second bellows have a second cross-sectional dimension that is smaller than the first cross-sectional dimension.

    Abstract: A pump may include a stator, a rotor, and an impeller. The stator may include one or more electromagnets and one or more permanent magnets. The rotor may include an armature, one or more complementary permanent magnets, and a pull magnet configured to position the rotor in an axial direction. The rotor may be disposed within the stator. The complementary permanent magnets and the one or more permanent magnets of the stator may create magnetic bearings. The armature may be aligned with at least one of the electromagnets of the stator and configured to rotate the rotor with respect to the stator. The impeller may be coupled to the rotor.
