Another highly efficient method for vacuum generation is the combination of a rotary vane vacuum pump with a vacuum booster (Fig. 3).A vacuum booster significantly increases the performance of the rotary vane vacuum pump. The right combination of a rotary vane vacuum pump (backing pump) and a vacuum booster allows for a high pumping speed which could otherwise only be achieved with a considerably larger individual vacuum pump – with correspondingly higher energy consumption. The results are shorter cycle times and considerable energy savings.
The energy consumption data should be carefully considered when selecting the vacuum pump. In addition, the size of the vacuum pump has to be adapted to the actual requirements. Possible alternative vacuum pump combinations must be considered for different packaging capacities. It is generally a good idea to consult a vacuum specialist with the necessary experience in the field of vacuum packaging who has an extensive product range of different vacuum generators.
