Abstract: 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.

Abstract: A reciprocating fluid pump includes a pump body, a first subject fluid chamber, a second subject fluid chamber, a first plunger at least partially defining a first drive fluid chamber and including a flexible material and configured to expand and compress in a reciprocating action to pump the subject fluid through the first subject fluid chamber within the pump body, and a second plunger located within the pump body and at least partially defining a second drive fluid chamber and including a flexible material and configured to expand and compress in a reciprocating action to pump the subject fluid through the second subject fluid chamber within the pump body, wherein the first plunger is not structurally coupled to the second plunger, such that the first plunger and the second plunger are independently movable during operation.

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.
