Description All Edwards nXDS15i high vacuum pumps rebuilt and sold through AVAC have been completely disassembled, cleaned, re-machined and carefully inspected for wear by our factory trained technicians. Units are assembled with new vanes, shaft seals, exhaust valves, gaskets, springs, oil pumps and bushings, prior to undergoing an extended performance test to meet or exceed OEM specifications. All pumps are then painted, detailed, and pass a final quality assurance inspection prior to shipping. A final test certificate is provided with each pump, which will be covered with a one-year warranty. The Edwards oil-free scroll pump is a reliable workhorse. With years of field experience and more performance hours than most competitors, the NXDS scroll pumps are the premium choice for clean pumping technology.Edwards Scroll Pump nXDS15i A73701983 8.9 cfm 1ph 115V/230V REBUILT W/ 1 Year Warranty A73701983 Specifications nXDS15iNominal rotational speed1802 rpmDisplacementm3h-1 (ft3min-1)17.1 (10.1)Peak pumping speedm3h-1 (ft3min-1)15.1 (8.9)Ultimate vacuum (total pressure)mbar (Torr)0.007 (0.005)Minimum standby rotational speedrpm1200Speed control resolution (percentage of full rotation speed)%1Max inlet pressure for water vapourmbar35Max water vapour pumping rategh-1240Maximum continuous inlet pressurembar200Voltage inputV100-127, 200-240 ( /-10%)Voltage frequencyHz50/62Motor power 1-ph*W300Power connector 1-ph-IEC EN60320 C15Recommended fuse-10A, 250V a.c. rmsWeightkg (lb)25.2 (56)Inlet flange-NW27Exhaust flange-NW27Noise level**dB(A)52Vibration at inlet flangemms-1 (rms)< 4.7Leak tightness (static)mbar ls-1< 1x10-8Operating temperature range°C (°F) 5 to 40 ( 41 to 104)
