R-VWP Series
Rotary Lobe Vacuum Pumps

Volume Flow 485 – 2,752 m3/hr

Elmo Rietschle, R-VWP Series, Rotary Lobe Vacuum PumpsThe contact free operating R-VWP series rotary lobe vacuum pumps have capacities ranging from 485 to 2,752 m3/hr.

Two symmetrically shaped rotors rotate against each other, synchronised by a pair of gear wheels in these twin lobe rotary vacuum pumps.

Able to tolerate water vapours and most corrosive gases, the R-VWP series rotary lobe vacuum pumps are primarily used for producing coarse and fine vacuum.

The R-VWP series are mainly used in combination with backing pumps. 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.
