Introducing the new nRVi series of oil sealed rotary vane pumps, designed to deliver an enhanced and consistent performance worldwide, with the latest in communication technology. Edwards’ field proven drive has been combined with the industry leading RV range, bringing oil sealed vacuum pump technology into the 21st century. Adding the new drive, based on Edwards technology, allows better installation and remote start/stop for improved control functionality. With autosensing wide range voltage operation users are assured that, regardless of the power supply (50 Hz or 60 Hz), the higher pumping speed would be achieved, for example turning an Edwards RV12 with a pumping speed of 12m3 h-1 into an nRV14i with speed of greater than 14 m3 h-1 and deliver an uprated and consistent performance worldwide.
