Edwards 12 RV12 Rotary Vane Dual Stage Mechanical Vacuum Pump A65501903

The RV series of small oil sealed rotary vane pumps deliver excellent ultimate vacuum pressure, high pumping speeds and superior vapour handling capabilities with quiet operation. With over 300,000 units produced, these pumps offer proven performance that sets the industry standard for R&D and scientific pumping applications. All RV pumps are approved to UL and CSA standards by an external test house and feature our unique mode selector switch, meaning one model is suitable for both high vacuum or high throughput applications.Specification:Displacement  50Hz 3.7 m3h-1 / 2.2 ft3min-1  60Hz 4.5 m3h-1 / 2.6 ft3min-1Speed (Pneurop 6602)  50Hz 3.3m3h-1 / 2 ft3min-1  60Hz 3.9 m3h-1 / 2.3 ft3min-1Ultimate pressure:2 x 10-3 mbar / 1.5 x 10-3 TorrUltimate pressure GB I:3 x 10-2 mbar / 2.3 x 10-2 TorrUltimate pressure GB II:1.2 x 10-1 mbar / 9.1 x 10-2 TorrUltimate pressure with Fomblin:2 x 10-2 mbar / 1.5 x 10-2 TorrMax inlet pressure for water vapour :80mbar / 60 TorrMax water vapour pumping rate – GB I:60 gh-1Max water vapour pumping rate – GB II:220 gh-1Max allowed outlet pressure:0.2 bar gauge / 2.8 psigMax allowed inlet and gas ballast pressure:0.5 bar gauge / 7 psigMotor power 50/60Hz:450 / 550WPower connector:1-ph IEC EN60320 C13Nominal rotation speed:50/60Hz 1500 / 1800rpmWeight (without oil):25 kg / 55 lbOil capacity min/max:0.42 / 0.7 litresRecommended oil:Ultragrade 19(not inculded)Inlet flange:NW25Exhaust flange:NW25Noise level:48 dB(A) @ 50 HzOperating temperature range:12 – 40 °C
