Abstract
In order to provide a simple and energy-efficient rough pumping method for a displacement pump (), intended to generate a maximum differential pressure (ΔP) between the inlet () and the outlet () of the displacement pump (), the rotational speed (Ω) of the displacement pump () is adjusted such that the maximum differential pressure (ΔP) to be generated that the power input () of the displacement pump () approximates the minimum power () physically required for compressing the gas in order to establish the maximum differential pressure (ΔP).
