A post-mix beverage dispenser system with removable pumps is disclosed. The system includes a pump enclosure for receiving a plurality of beverage syrup pumps. Each beverage syrup pump may be easily removed from the enclosure and replaced in a tool-less manner. A sensor and control system for the plurality or removable pumps is also disclosed.

A beverage dispenser with a variable pressure regulator cap assembly that includes a high pressure cavity defined by a cap body. The high pressure cavity receives pressurized gas from a compressed gas reservoir. A low pressure cavity is connected to the high pressure cavity via a high pressure gas passageway. The low pressure cavity defines a low pressure gas passageway that penetrates the cap body. A piston seat is positioned on a high pressure cavity side of the high pressure gas passageway. A piston regulates introduction of the pressurized gas into the high pressure gas passageway. A diaphragm is positioned between an ambient pressure cavity and the low pressure cavity and translates the piston relative to the piston seat. A main spring is positioned between a diaphragm and a spring hat. Rotation of the drive screw translates the spring hat to affect compression of the main spring against the diaphragm.

A portable CO2 based cooler and beverage dispensing system for pressurizing and cooling beverage tanks, comprises a vibration-absorbing portable shell with a snap on removable tray for holding beverage containers and ice-cream-recesses, two growler-vibration-absorbing circular springs molded on the shell bottom for absorbing vibration from transportation and for holding and separating two beverage tanks, a tank-vibration-absorbing circular spring molded on the shell bottom for absorbing vibration from transportation and for holding a pressurized tank, a clamping system for clamping on and stabilizing two beverage growlers and a pressurized tank for transportation, two multi-height spigots, two height-adjustable telescopic posts, and a retractable height-adjustable spigot-locking handle attached the two posts and having two spigot-locking receptacles molded thereon for locking and adjusting the multi-height spigots to multiple different heights.

Various systems, processes, and techniques may be used to achieve beverage dispensing. In particular implementations, a beverage dispensing system may include a housing, a water inlet, a dispensing faucet, and a tray. The housing may include a base and at least one vertically extending wall that defines an inner cavity at least at the top of the housing. The water inlet and the dispensing faucet may be coupled to the housing. The tray may be adapted to couple to the housing and be suspended in the inner cavity. The tray may have walls and a lower surface that define a cavity adapted to hold a beverage concentrate container, the lower surface being slanted relative to the base of the housing when the tray is coupled to the housing. The lower surface may have an connector fitting adapted to receive a beverage concentrate conduit.

A portable beverage dispenser with a variable pressure regulator cap assembly that includes a high pressure cavity defined by a cap body. The high pressure cavity receives pressurized gas from a compressed gas reservoir. A low pressure cavity is connected to the high pressure cavity via a high pressure gas passageway. The low pressure cavity defines a low pressure gas passageway that penetrates the cap body. A gauge, such as a pressure and/or temperature gauge provides feedback about characteristics of the beverage contained within the dispenser.
