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. 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(110V):14.2 m3h-1 / 8.4 ft3min-1 60Hz(115V-120V):17 m3h-1 / 10 ft3min-1Speed (Pneurop 6602) 50Hz(110V):12 m3h-1 / 7.1 ft3min-1 60Hz(115V-120V):14.2 m3h-1 / 8.4 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 : 6 x 10-2 mbar / 4.6 x 10-2 TorrUltimate pressure with Fomblin:2 x 10-2 mbar / 1.5 x 10-2 TorrMax inlet pressure for water vapour:32 mbar / 24 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): 29 kg / 63.8 lbOil capacity min/max: 0.65 / 1 litresRecommended oil:Ultragrade 19(not included)Inlet flange:NW25Exhaust flange:NW25Noise level:48 dB(A) @ 50 HzOperating temperature range:12 – 40 °CNote:The power connector of the vacuum pump is 1-phase, if you need 3-phase，please contact us.

• High reliability – generous lubrication of moving parts. Safe process and systems – fast acting inlet valve for best in class anti‑suck back protection.
• Configured to meet your vacuum needs – mode selector and two position gas ballast. No unplanned downtime – designed for easy maintenance.
• Better work environment – quiet running and intrusive frequencies minimised. Two position gas ballast allows either 60 g/hr or a class leading 220 g/hr (290 g/hr on RV12) of water vapour to be handled. Universal motor to cover the widest possible voltage and frequency range from a single variant.
• Smooth controlled inlet valve opening by oil pressure to eliminate pressure surges. Rapid closing inlet valve within 0.4 seconds of pump stopping.
• Pump oil is not included, please purchase the pump oil separately.Recommended oil:Ultragrade 19(Not inculded)
