Edwards nES40 – single-stage rotary vane vacuum pump of the nES series
The nES40 belongs to the nES series, Edwards' new generation of single-stage oil-sealed rotary vane pumps for a wide range of industries and applications. It delivers 38.5 m³/h at 50 Hz and 47 m³/h at 60 Hz and reaches an ultimate pressure of 0.5 mbar without gas ballast, 1.5 mbar with gas ballast. The motor power is 1.3 kW at 50 Hz and 1.3 kW at 60 Hz. The pump weighs around 67 kg and measures about 540 × 284 × 303 mm (L × W × H).Features of the nES series
- Stable vacuum performance without pressure fluctuations thanks to optimised oil distribution; high pumping speed at low pressures
- Low life-cycle costs thanks to efficiently cooled motors, low pump temperature and low maintenance effort
- Optimised oil return and separation system with integrated oil mist filters for low oil losses
- Gas ballast for pumping condensable vapours
- Low noise and vibration levels
- Connections either to ISO or with G thread
- ULTRAGRADE Performance 70 for optimum pumping performance; ULTRAGRADE Endurance Extend 110 for longer service intervals
