Edwards nXDS20iR Dry Scroll Pump

Edwards nXDS20iR Dry Scroll PumpUltimate Vacuum0.030 mbar / 0.022 TorrInlet FlangeNW25Displacement28.0 m3h-1 / 16.5 ft3min-1FeaturesBearing shield ensures separation between process gases and bearing lubrication to ensure clean vacuum and no possibility of contamination.Smart motor drive means consistent performance globally, pump overload protection and remote start/stop capability.High flow gas ballast feature allows pumping of vapours including water vapour at up to 240 gh-1Simple single sided scroll design allows maintenance to be done in minutes for low cost of ownership and maximum up-time.Enhanced versions offer up to 20% lower peak power requirements during initial pump down.The nXDS allows a wide range of control and communication options The nXDS comes as standard with a manual, easy to use, gas ballast port A perfect companion for your turbomolecular pump With exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features Edwards nXDS is the best performing pump in its class. nXDS improves on legacy XDS pumps by offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise – up to 20 times quieter than other pumps. Gas ballast allows for pumping of condensable vapours including, water, solvents, dilute acids and bases. nXDS pumps also feature the latest in tip seal technology giving significantly longer life between tip seal changes. Integrated inverter drive with auto sensing voltage input delivers optimised pumping performance globally. Unlike the standard nXDS20i, the Edwards nXDS20iR is designed for specialist applications such as gas recirculation, rare gas pumping and recovery or other applications where the dilution of the pumped gas is undesirable, or where sealing is integral to minimizing potential gas loss.  Click Here to View Product VideoINCLUDED:The Edwards nXDS20iR Dry Scroll Pump includes:Power CordOperator’s ManualManufacturer’s Documentation1 Year Manufacturer’s WarrantyEdwards nXDS20iR Dry Scroll Pump Technical SpecificationsNominal rotational speed1800 rpmDisplacement28.0 m 3h-1 / 16.5 ft3min-1Peak pumping speed22.0 m 3h-1 / 13.0 ft3min-1Ultimate vacuum (total pressure)0.030 mbar / 0.022 TorrMinimum standby rotational speed1200 rpmSpeed control resolution (percentage of full rotation speed)1%Pumping speed at minimum rotational speed10Maximum continuous inlet pressure50 mbarMotor power 1-ph260 WPower connector 1-phIEC EN60320 C13Recommended fuse10A, 250Vac rmsInlet flangeNW25Exhaust flangeNW25Noise level52 dB(A)Vibration at inlet flange< 4.5 mms -1 (rms)Leak tightness (static)< 1×10 -6 mbar ls-1Operating temperature range10 to 40 °C / 41 to 104 °FWeight25.6 kg / 56 lbElectrical Supply100-127/200-240V, 50/60Hz, 1PhComparison of ModelsSpecificationEdwards nXDS6iREdwards nXDS10iREdwards nXDS15iREdwards nXDS20iRNominal rotational speed (rpm)1800180018001800Displacement (m³h⁻¹ / ft³min⁻¹)6.2 / 3.612.7 / 7.517.1 / 10.128.0 / 16.5Peak pumping speed (m³h⁻¹ / ft³min⁻¹)6.2 / 3.611.4 / 6.715.1 / 8.922.0 / 13.0Ultimate vacuum (total pressure) (mbar / Torr)0.020 / 0.0150.007 / 0.0050.007 / 0.0050.030 / 0.022Weight (kg / lb)26.2 / 5825.8 / 5725.2 / 5625.6 / 56Inlet flangeNW25NW25NW25NW25Noise level (dB(A))52525252Operating temperature range (°C / °F)10 to 40 / 41 to 10410 to 40 / 41 to 10410 to 40 / 41 to 10410 to 40 / 41 to 104Electrical Supply100-127/200-240V, 50/60Hz, 1Ph100-127/200-240V, 50/60Hz, 1Ph100-127/200-240V, 50/60Hz, 1Ph100-127/200-240V, 50/60Hz, 1PhDownloads Technical Specification DownloadOperator's Manual Download Request a Formal QuoteFrequently Purchased WithEdwards Silencer for nXDS and XDS5/10 Dry Scroll Pumps Add to Cart+Edwards nXDS Gas Ballast Adapter Kit Add to Cart
