Twin lobe
Rotary lobe vacuum pumps R-VWP can be used in many applications that need coarse or fine vacuum. Two
symmetrically shaped rotors rotate against each other, synchronized by a pair of gear wheels. The pumps are dry
running, and consequently the compression chamber is free of grease or oil. Gear box and bearings are oil
lubricated. A bypass valve integrated in the housing enables the start of the pump together with the backing pump to
avoid an overload of the motor at high differential pressures.
Rotary lobe vacuum pumps
Contact free operating rotary lobes with capacities ranging from 485 to 2,752 m³/h. Primarily used for producing
coarse and fine vacuum and for handling gases and vapors, as they can tolerate water vapor and most corrosive
gases. Mainly used in combination with backing pumps.
