Description Edwards E2M30 Vacuum Pump. 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. Edwards E2M30 Vacuum Pump 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 capacityEdwards Vacuum Pump E2M30 1 PHASE 115/230V 22.5 cfm REBUILT w/ 1 Year Warranty Specifications E2M3050 Hz electrical supply19 cfm60 Hz electrical supply23 cfmMaximum pumping speed - Pneurop50 Hz electrical supply16.2 cfm60 Hz electrical supply19.4 cfmMotor rotational speed50 Hz electrical supply1440 r min·160 Hz electrical supply1720 r min⁻1Ultimate vacuumwithout gas-ballast (partial pressure)7 x 10⁻5 torrwithout gas-ballast (total pressure)7 x 10⁻4 torrwith full gas-ballast (partial pressure)1.5 x 10⁻1 torrMaximum water vapour inlet pressure22.5 torr
