| Summary: | The article is devoted to a theoretical study to substantiate the design parameters of the impeller, an installation for the preparation of liquid feed mixtures created on the basis of a paddle pump. In the study of the pump, the indicator of the supply of liquid feed mixtures was taken as a basis. When calculating and determining the parameters, the theory of vane pumps was used, based on the laws and provisions of the hydromechanics of an ideal and viscous practically incompressible fluid. The proposed installation is universal and can be used both as a mixer and as a pump. Theoretical experiments were also carried out using the theory of experiment planning, as a result, regression equations were obtained.
