Description 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. To meet the requirements for high throughputs with low ultimate vacuum, Edwards has developed a totally new concept in rotary vacuum pumps: The world's first dual-mode pump. The unique dual-mode action allows you to easily configure the unit to pump very high gas loads and also achieve excellent vacuum - all from a single pump. In most cases it increases performance at significantly reduced noise levels. This unique performance is matched by innovative design features including a cartridge based pumping mechanism incorporating advanced new materials, a fully featured Edwards motor and a fast acting inlet valve to seal the pump for suck-back protection. The pumps are easy to install, use and maintain with superior built quality to give lowest cost of ownership. To build a pump this advanced, Edwards has invested heavily in state-of-the-art manufacturing and assembly technology in a dedicated ISO9001 factory. Edwards RV - easy to install, use and maintain Installation is easy as all Edwards RV pumps feature a special dual voltage, dual frequency motor with an IEC mains input socket. Simply plug in the appropriate cable. No need for hard wiring. An on/off switch controls the pump. The motor voltage is determined by a simple rocker switch, enabling the pump to be easily configured for use internationally. All controls are clearly marked and have large finger grips for ease of use. Inlet and outlet are both fitted with standard NW25 flanges.Selectable dual modeHigh vacuum for best pressureHigh throughput mode for continuous inlet pressure above 50 mbarEasy to use gas ballastON-OFF switch on pumpLow Noise Level: 48 dbAAll pumps factory tested and certifiedEasy to service and maintainEdwards Vacuum Pump RV12 10 cfm Specifications SpecificationsHzUnits RV 12VACUUM DATAPeak pumping speed60cfm8.450m3/h12Ultimate pressure (Total)60Torr1.5 x 10-350mbar2.0 x 10-3Ultimate pressure GB I (Total)50/60Torr2.3 x 10-2mbar3.0 x 10-2Ultimate pressure GB II (Total)50/60Torr9.1 x 10-2mbar1.2 x 10-1High throughput mode50/60Torr2.3 x 10-2mbar3.0 x 10-2Water vapor toleranceTorr24mbar32Water vapor capacity - GB Ig/h60Water vapor capacity - GB IIg/h290MOTOR DATAMotor rating 1 phase (nominal)60W55050W450Motor rating 3 phaseWNominal rotation speed60rpm180050rpm1500PHYSICAL DATAWeightlb58kg26.3Lengthinch19.3mm490Widthinch6.2mm158Heightinch8.9mm225Oil capacityliters1Inlet flangeNW25Exhaust flangeNW25Noise level50dBA48Operating temperature range°C12 to 40
