Claim 0:
1. A pumping apparatus for dispensing a flowable product, the apparatus comprising:
a first peristaltic pump comprising:
a first drivable rotor having at least one pressing member;
a first cylindrical stator in which the first drivable rotor is rotatable, the first cylindrical stator having a first circumferential inner wall with a first radius;
first flexible tubing having an inlet side and an outlet side, the first flexible tubing extending circumferentially around the first cylindrical stator against the first circumferential inner wall;

a second peristaltic pump comprising:
a second drivable rotor having at least one pressing member;
a second cylindrical stator in which the second drivable rotor is rotatable, the second cylindrical stator having a second circumferential inner wall with a second radius;
second flexible tubing having an inlet side and an outlet side, the second flexible tubing extending circumferentially around the second cylindrical stator against the second circumferential inner wall;

wherein the first radius is greater than the second radius and at least one of the stators is movable horizontally and vertically relative to the other stator during pumping via the pumping apparatus.
