PUMP UNIT FOR DOSING FLUID PRODUCT Russian patent published in 2023 - IPC F04B43/12 F04B43/08 

FIELD: dosing equipment.

SUBSTANCE: invention relates to dosing of fluid products, in particular, to a pump unit for dosing a fluid product. The pump unit for dosing a fluid product contains first and second peristaltic pumps 12, 14. First pump 12 contains first rotor 18 having at least one pressure element 20, first cylindrical stator 19, in which rotor 18 is made with the possibility of rotation, and first flexible tube 30 extending along a circumference around stator 19 opposite to first inner wall 19a. Second pump 14 contains second rotor 42 having at least one pressure element 46, second cylindrical stator 44, in which rotor 42 is made with the possibility of rotation, and second flexible tube 54 extending along a circumference around stator 44 opposite second inner wall 44a. Each first and second walls 19a, 44a have first and second radius r1, r2, respectively. Radius r1 is greater than radius r2, and at least one of stators 19, 44 is movable relatively to the other stator 19, 44.

EFFECT: invention is aimed at provision of dosing with a greater degree of accuracy.
