The paper describes the results of investigating the influence of the backing pump parameters on the pumping parameters of the turbo vacuum pump. On the basis of the calculation program developed, we for the first time obtained the data on the mutual influence of their pumping performance. These data allowed us to select specific types of pumps while ensuring optimal parameters throughout the pumping system. We also give some recommendations on determining the ratio between the maximum values of the fast action of the backing and turbomolecular vacuum pumps.
