Abstract
A peristaltic pump for pumping a liquid, such as a juice concentrate, includes a rotor assembly attached to a housing, a band attached to the housing and surrounding at least a portion of the rotor assembly A tube is positionable between the band and the rotor assembly. The position of the band can be adjusted relative to the rotor assembly to adjust the pressure applied to the tube by the band and the rotor assembly. The rotor assembly includes rollers therein for pumping concentrate from a reservoir by drawing a vacuum.
