Description Edwards E2M28 Vacuum Pump Rebuilt. All 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 distribution valves and bearings 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 EM range of oil-sealed rotary pumps - renowned for its high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapor - has become the industry standard for laboratory applications. All pumps in the range are independently approved to UL and CSA standards. EM Series Oil-Sealed Rotary Vane Vacuum Pumps EM Series pumps are rugged, mechanical oil-sealed pumps with speeds ranging from 0.7 to 28 m3/hr depending on model size and stage. Compact and quiet, they feature advanced lubrication circuits, high reliability, and accessories to suit your specific application needs.Quiet Operation: Better Working EnvironmentReliable Performance: Proven in a range of laboratory and industrial applicationsFree standing unit and compact design: Flexibility of useGas ballast valve: Large vapor handling capacityClick Below for Brochure Edwards Vacuum Pump E2M28Edwards E2M28 Vacuum Pump 1 PHASE 115/230V 22.5 cfm Specifications Displacement (swept volume)50 Hz32.2 m3h-1 / 19 ft3min-160 Hz38.9 m3h-1 / 22.3 ft3min-1Speed (Pneurop 6602)50 Hz27.5 m3h-1 / 16.2 ft3min-160Hz33.0 m3h-1 / 19.5 ft3min-1Ultimate vacuum (total pressure)without gas ballast1 x 10-3 mbar / 7.5 x 10-4 Torrwith gas ballast1.5 x 10-2 mbar / 1.1 x 10-2 Torrwith Fomblin®1 x 10-2 mbar / 7.5 x 10-3 TorrInlet connectionNW25 flangeOutlet connection**Nozzle 15 mm external Ø removable from 3/4 in BSP tapped holeMax allowed pressure at outlet0.5 bar gauge / 7 psigMax inlet pressure for water vapour30 mbar / 23 TorrMax water vapour pumping rate0.7 kg h-1Operating temperature range13 – 40 °CNominal rotation speed1440 / 1720 rpmMotor power 50 Hz0.75 kWMotor power 60 Hz0.90 kWPower Connector 1-ph*IEC EN60320 C19Weight44 kg / 97 lbsNoise57 dB(A) @ 50 HzOil capacity - max1.5 litreOil capacity - min1.2 litre
