The touch-free operating and oil-free compressing roots booster pump represents an efficient solution for pumping stations used in the food packaging industry (primary packaging). The evacuation speed is considerably increased compared to the single vacuum pump integrated into the packaging machine. With its integrated bypass it offers high operational reliability and availability for high-performance packaging processes. The roots pump supplements an existing vacuum pump. Together with this backing pump it offers compact partial centralization. The backing pump used is an oil-lubricated rotary-vane vacuum pump by Becker.
