A microfluidic dispensing system may include multiple supply lines for simultaneous filling of diaphragm pumps associated with each supply line. Each supply line may fill corresponding groups of diaphragm pumps with a corresponding ingredient to a supply reservoir for the supply line. Accordingly, different groups of diaphragm pumps corresponding to different supply lines may be filled with corresponding ingredients simultaneously. Those ingredients corresponding to the different groups of diaphragm pumps may also be dispensed simultaneously, giving rise to a faster and more efficient fluidic dispensing system.
