摘要： 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.

摘要： A multi-port metering pump assembly includes a manifold coupled to a metering pump. The manifold defines a central passage in fluid communication with a plurality of intermediate passages defined in the manifold. The manifold includes a plurality of outer passages. Each intermediate passage provides fluid communication between the central passage and a corresponding outer passage. A plurality of valves is coupled to the manifold. Each valve of the plurality of valves is located between an intermediate passage and a corresponding outer passage, and is configured to enable or prevent passage of fluid between a corresponding intermediate passage of the plurality of intermediate passages and a corresponding outer passage. The multi-port metering pump assembly also includes an electronic controller coupled to the plurality of valves, the electronic controller having an associated electronic interface and being programmable to selectively and independently open and close the valves of the plurality of valves.

摘要： A fitting assembly may seal a wire within a tube to inhibit ingress of fluid outside the tube into the tube and into contact with the wire. The fitting assembly may optionally include a body and a nut, with a part of the nut received within the body. The nut may be threadedly connected to the body, such that threading and/or unthreading the nut translates the part of the nut within the body. Optionally, the nut may include a ring extension that is received within a ring cavity of the body, and an interfacing between the ring extension and the ring cavity may create a seal to inhibit leaking of the fluid past the seal. A method of sealing a wire within a tube may comprise positioning a tube with a wire therein within such a fitting assembly.

摘要： A pneumatic reciprocating fluid pump for pumping a fluid includes at least one check valve assembly that includes a check valve body insert, a ball within the valve body insert, and an annular sealing ring member disposed within a seat ring receptacle. The sealing ring member has dimensions smaller than corresponding dimensions of the seat ring receptacle, such that the sealing ring member is capable of moving within the seat ring receptacle. The ball is configured to slide back and forth between a first position and a second position within the check valve body insert responsive to forward and reverse flow of fluid therethrough. In one position, the ball is seated against the sealing ring member and prevents reverse flow of the fluid through the check valve assembly, and forward flow of the fluid through the check valve assembly is enabled when the ball is in another position.

摘要： Reciprocating fluid pumps include a reinforced shaft including an inner shaft and a protective cover. The protective cover at least substantially encapsulates the inner shaft. The inner shaft exhibits a greater resistance to mechanical deformation than the protective cover, and the protective cover exhibits a greater resistance to chemical corrosion by the subject fluid than the inner shaft. Methods of forming a reciprocating fluid pump include forming a reinforced shaft and positioning the reinforced shaft within a subject fluid chamber and between two plungers.

摘要： A reciprocating fluid pump may include a pump body, one or more subject fluid chambers within the pump body, one or more drive fluid chambers within the pump body, and a shuttle valve for shifting flow of pressurized drive fluid between two or more conduits. The shuttle valve includes a valve body and a spool disposed within the valve body and configured to move between a first position and a second position within the valve body. The shuttle valve also includes one or more magnets carried by the spool. The magnets are located and configured to impart a force on the spool responsive to a magnetic field such that the spool is magnetically biased away from an intermediate position between the first position and the second position.

摘要： Reciprocating fluid pumps include a pump body including a cavity therein, a plunger located at least partially within the cavity, and a shift canister assembly disposed within the cavity. The shift canister assembly includes a sealing surface for forming a seal against the pump body. An area covered by the seal between the sealing surface and the pump body is less than about 75% of an outer cross-sectional area of the shift canister assembly. The shift canister assembly may include a shift canister and a shift canister cap attached thereto, the shift canister cap comprising the sealing surface. Reciprocating fluid pumps include a shift canister, a shift piston at least partially disposed within the shift canister, and a shift canister cap attached to the shift canister on a longitudinal end of the shift canister opposite the shift piston. Methods include forming such reciprocating pumps.
