In this paper, a separate type vacuum pump with single vane was designed and manufactured for brake booster of diesel vehicles. The CATIA software was applied in modeling of vacuum pump components and the elastohydrodynamic lubrication analysis was carried out to predict the lubrication conditions between the vane tip and inner surface of casing. The results showed that fully hydrodynamic lubrication condition can be sustained even at lower speeds, and high vacuum performance was obtained. Therefore the results obtained can be used in improvement of all types of vacuum pump.
