Methods and apparatus for pumping and dispensing are provided in which a peristaltic pump ( 16, 64 ) pumps liquid from a package ( 12 ), and may be integrated in a dispenser ( 10 ). The peristaltic pump ( 64 ) is adapted for improved accuracy, cleaning, and maintenance. Also provided are improved tubes ( 18 ) for peristaltic pumping that are coupled to self-sealing dispensing valves ( 92, 104, 110, 120 ).
