Abstract: An illustrative embodiment of the present disclosure includes a pump having a rotor and a plurality of vanes. The rotor is attached to a motor that rotates it in first and second directions and is located in a cavity. The plurality of vanes are each pivotally coupled to the rotor so as the rotor rotates, the vanes selectively push fluid from an inlet port out through an outlet port. The plurality of vanes each have an end selected from the group consisting of a lobe, no lobe, and a rod located in the lobe. Each of the plurality of vanes also includes a pivot pin configured to fit in a corresponding receptacle located in the rotor so that each of the plurality of vanes is pivotable with respect to the rotor inside the cavity.

Abstract: A fluid transfer pump assembly that includes a motor enclosure assembly that forms a motor cavity sized to receive a motor. The motor enclosure includes a flame path that extends from an interior joint to an exterior joint. The interior joint faces the motor cavity and the exterior joint faces exterior of the motor enclosure assembly. A heat sink is located in the motor cavity of the motor enclosure assembly. A portion of the heat sink abuts the interior joint.

Abstract: A fluid transfer pump assembly is provided that includes an electronic device enclosure, a bore, and a vent pin. The electronic device enclosure includes a wall separating an interior from an exterior of the explosion-proof fluid transfer pump assembly. The electronic device enclosure includes a bore extending through the wall of the electronic device enclosure from the interior of the electronic device enclosure to the exterior of the explosion-proof fluid transfer pump assembly. The bore is formed by at least one peripheral surface extending from the interior of the electronic device enclosure to the exterior of the explosion-proof fluid transfer pump assembly. The vent pin extends into the bore. The vent pin fills space within the bore and engages the at least one peripheral surface except that at least one portion of a pin surface of the vent pin is spaced apart from at least one portion of the at least one peripheral surface of the bore.

Abstract: A universal closure valve adapter attachable to a neck wall of a first container that forms a periphery of an opening having a diameter. The universal closure valve adapter includes a closure valve assembly that is attachable to a closure valve assembly of a second container. A flange transversely extending from the closure valve assembly of the first container. The flange includes a plurality of tank neck engagement assemblies. Each of the plurality of tank neck engagement assemblies are spaced apart from each other about the flange.

Abstract: A measuring a closed-loop fluid transfer system is provided that includes a measuring adapter having a first end and a second ends, and a chamber located there between and configured to hold a volume of fluid. The measuring adapter includes a first receiving valve assembly located at the first end of the measuring adapter. The first receiving valve assembly includes a receiving valve member, at least a portion of which is separable from a portion of the first receiving valve assembly. This creates an opening that provides fluid communication to the chamber when a force is exerted on the receiving valve member of the first receiving valve assembly. A second valve assembly located at the second end of the measuring adapter includes a valve member. At least a portion of the valve member of the second valve assembly is separable from a portion of the second valve assembly to create an opening that provides fluid communication to the chamber.

Abstract: The present disclosure provides a metered dosing assembly configured to dispense a volume of fluid into a container that is selectively sealed by a closure valve having a closure valve member that is movable between sealed and unsealed positions with respect to the container. The metered dosing assembly includes a housing having an interior cavity. A valve is locatable at an end of the housing. The valve includes a valve member, a pin extending from the valve member, and at least one spring leg attachable to the valve member. The pin extends from the valve member and is configured to engage the closure valve member of the closure valve to move the closure valve member to the unsealed position and move the valve member to an open position with respect to the housing. When the valve member is moved to the open position and the closure valve member is moved to the unsealed position, fluid communication is made between the metered dosing assembly and the container.

Abstract: An expanded flow rate receiver valve assembly attaches to a first fluid container and is in fluid communication with the first fluid container. The expanded flow rate receiver valve assembly includes a coupling section that selectively receives a closure valve attached to a second fluid container that selectively releases and restricts fluid contained in the second fluid container. The expanded flow rate receiver valve assembly also includes a valve chamber in fluid communication with the coupling section and located adjacent a coupling section opening. The valve chamber is in fluid communication with the first fluid container.
