Edwards nES300S – single-stage rotary vane vacuum pump of the nES series
The nES300S 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 284 m³/h at 50 Hz and 330 m³/h at 60 Hz and reaches an ultimate pressure of 0.08 mbar without gas ballast, 0.7 mbar with gas ballast. The motor power is 6 kW at 50 Hz and 7.2 kW at 60 Hz. The pump weighs around 244 kg and measures about 1117 × 565 × 450 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
