More Details

The new and improved nRVi series of oil sealed rotary vane pumps are developed to provide upgradation and stability in global performance along with the brand new communication technology. The oil sealed vacuum pump technology is introduced in the 21st century by integrating the Edwards' field proven drive with the leading RV range.

An improvance in control is attained by using the nXDS technology in the new drive which is added for better installation and remote start/stop functions. The new autosensing wide range operation provides greater pumping speeds that are achieved regardless of power supply (50 Hz or 60 Hz) making the Edwards RV12 with 12m3h-1 pumping speed into an nRV14i with 14m3h-1 pumping speed to provide enhancement and stability in global performance.
