A system for dispensing fluid may include a first fluid circuit and second fluid circuit. The first fluid circuit may include a first reservoir configured to contain a supply of first fluid for being dispensed and a first variable volume chamber in flow communication with the first fluid circuit. The second fluid circuit may be configured to provide pressure for dispensing the first fluid. The second fluid circuit may include a second reservoir, a pump, fluid passages configured to provide fluid flow within the second fluid circuit, and a second variable volume chamber in flow communication with the second fluid circuit. The second fluid circuit may be a closed-loop circuit, and the first variable volume chamber and the second variable volume chamber are associated with one another, such that flow of fluid in the second circuit controls dispensing and temperature of the first fluid in the first fluid circuit.
