Abstract: 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.

Abstract: A pneumatic reciprocating fluid pump for pumping a fluid 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.

Abstract: 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.

Abstract: A fluid pump includes a pump body enclosing a first cavity and a second cavity, a first flexible member disposed within the first cavity, a second flexible member disposed within the second cavity, and a drive shaft extending between and attached to each of the first flexible member and the second flexible member. The drive shaft is configured to slide back and forth within the pump body. The pump also includes a first shift valve and a second shift valve disposed between the first flexible member and the second flexible member, operatively coupled to deliver a drive fluid to drive fluid chambers in alternating sequence. Some fluid pumps disclosed herein include a housing defining a modular-receiving cavity and a modular insert secured within the modular-receiving cavity by an interference fit. Methods of manufacturing and using fluid pumps are also disclosed.

Abstract: 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.
