EMS Technical Data Sheets
Edwards RV3 Vacuum Pump
EMS #91003, 91003-E
The Edwards RV3 Vacuum Pump delivers excellent vacuum pressure, high pumping speeds, and superior vapor handling capabilities, with quiet operation. These pumps offer proven performance that set the industry standard for R&D and scientific pumping applications.
Our significantly quieter pumps produce noise levels of 48 dBA 50Hz, which is typically half the noise of a conventional pump and have been achieved by extensive work on the drive train and motor.
The pumps have the unique ability to deliver ultimate vacuum in both high vacuum and high throughput modes, with or without gas ballast. This gives the user an unrivalled opportunity to select the optimum pumping performance without compromising the application.
In its high vacuum mode, the RV pump is ideal for analytical instruments, electron microscopes, physics research, backing turbo pumps, and leak detection applications. Configure the same pump in the high throughput mode and it becomes suitable for distillation, laboratory furnaces, backing vapor pumps, solvent concentration, freeze drying, and other drying applications.
The simple to use mode selector and accessible, three-position gas ballast control allow the pump to be reconfigured at any time, even when the pump is running.
The Edwards RV3 Vacuum Pump can be used in a variety of applications:
- Analytical Instruments
- Laboratory Bench Top Vacuum
- Turbomolecuar Backing Pumps
- Freeze Drying
- Research and Development
- Centrifuges, Ultra-High Speed
- Coating
- Degassing/Curing – Oil, Epoxy Resin
- Distillation/Extraction/Filtration
- Furnaces
- Gas Bottle Filling/Emptying
- Gel Drying
- Glove Boxes, Ovens
- Leak Detectors, Helium
- Load Locks and Transfer Chambers
- Refrigeration Manufacture
- Rotary, Centirfugal Evaporators
- Scanning Electron Microscopes (SEM)
- SEM/FIB (Ion Beam Repair)
- Solvent Recovery
- Surface Science Instruments
