R-VWP Series Rotary Lobe Vacuum Pumps
The 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.
Dry runningThese rotary lobe vacuum pumps are dry running. Consequently the compression chamber is free of grease or oil. Only the gear box and bearings are lubricated.
Robust & economicalLike all of the other models in the R series, the Elmo Rietschle R-WVP series of rotary lobe vacuum pumps are robust and economical.
