The primary transport two-stage rotating oil vacuum pump is designed for pumping enclosed volume of 105 Pa by pumping rate of 8 m3 / h. The possibility of using them is in the laboratory and industrial environments.

The intake air must not contain any mechanical impurities, aggressive gases and vapors and do not form with oil-filled explosive or aggressive mixture. Vacuum pump drives the single-phase motor, which forms with pump a compact pump unit.
