Edwards E2M30 Pump Vacuum Pump Rotary Vane 23 cfm 1E-3 mbar 240V 50 60 Hz tested

Product Information

Edwards E2M30 Rotary Vane Vacuum Pump, serial 119461878, made in Czechia. This used unit is in Good condition and functional; it powers on and passed a basic bench check, achieving approximately 0.0547 mbar in our shop test. Full performance verification was not performed and it is offered AS-IS. The E2M30 is a two-stage, oil-sealed rotary vane pump with pressurized lubrication and an oil distribution anti-suckback valve to prevent backstreaming at shutdown. A gas-ballast valve enhances vapor handling for wet processes. Displacement is 19 cfm at 50 Hz and 23 cfm at 60 Hz, with ultimate pressure to 1E-3 mbar (dry), and up to 0.7 kg h-1 water vapor pumping at 30 mbar inlet. The enclosed single-phase motor is fan-cooled and protected by an automatic-reset thermal overload. Electrical input: 200–240 V, 50/60 Hz. Noise is 57 dBA at 50 Hz. Ideal as a foreline/backing pump for mass spectrometers, leak detection, electron microscopy, vacuum drying, and general lab vacuum. Includes power cord only.
