Edwards nES630 – single-stage rotary vane vacuum pump of the nES series
The nES630 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 640 m³/h at 50 Hz and 755 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 18.5 kW at 50 Hz and 18.5 kW at 60 Hz. The pump weighs around 760 kg and measures about 1563 × 909 × 740 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
Versions of the Edwards nES630
The nES630 is available in 5 versions (part numbers A35904950, A35905950, A35924950, A35925950, A35904937). The market details (worldwide incl. Japan, Asia, Canada) come from the Edwards brochure and the Edwards webshop; versions without a market detail apply worldwide. The water-cooled versions need 750 l/h of cooling water at 2–8 bar and no more than 30 °C.Advice and service
