It is shown that during machining of centrifugal pumps impellers the condition of geometric similarity is not fulfilled, that’s why comparable pumps are not geometrically similar. It is shown, that according experiments ratio of motion of such pumps is proportional to the diameter of machined and not-machined impellers.
