Patent number: 10253761Abstract: 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.Type: GrantFiled: June 6, 2016Date of Patent: April 9, 2019Assignee: White Knight Fluid Handling Inc.Inventors: John M. Simmons, Tom M. Simmons, Kenji Allen Kingsford, David M. Simmons

Patent number: 9970430Abstract: 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.Type: GrantFiled: February 10, 2017Date of Patent: May 15, 2018Assignee: WHITE KNIGHT FLUID HANDLING INC.Inventors: Kenji Allen Kingsford, Tom M. Simmons, Ervin Andy Hutchinson, Courtney Parsons

Patent number: 9856865Abstract: 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.Type: GrantFiled: November 19, 2013Date of Patent: January 2, 2018Assignee: White Knight Fluid Handling Inc.Inventors: John M. Simmons, Tom M. Simmons, David M. Simmons, Kenji Allen Kingsford, Ervin Andy Hutchinson

Patent number: 8622720Abstract: Reciprocating fluid pumps include a plunger configured to expand and compress in a reciprocating action to pump fluid, and one or more magnets carried by the plunger. The one or more magnets may be used to impart a force on the plunger when the plunger expands and compresses in the reciprocating action within a pump body responsive to a magnetic field. Shuttle valves for shifting flow of pressurized fluid between at least two conduits include a spool movable within a valve body and one or more magnets carried by the spool. The one or more magnets may be used to impart a force on the spool responsive to a magnetic field. Reciprocating fluid pumps may include such shuttle valves. Methods include forming and using such pumps and shuttle valves.Type: GrantFiled: September 9, 2011Date of Patent: January 7, 2014Inventors: Tom M. Simmons, John M. Simmons, David M.
