Edwards RV5 Vacuum Pump

EMS Catalog #91005, 91005-E

The RV series of small oil sealed rotary vane pumps deliver ultimate vacuum pressure, high pumping speeds and superior vapor handling capabilities with quiet operation.

All of our RV pumps are significantly quieter – noise levels of 48 dBA 50Hz are typically half the noise of a conventional pump and have been achieved by extensive work on the drive train and motor.

These 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, TV tube pumping and leak detection applications. Configure the same pump in the high throughput mode, and it becomes suitable for mass spectrometer inlet systems, 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 RV5 Vacuum Pump can be used in a variety of applications:

  • Analytical instruments
  • Centrifuges, ultra-high speed
  • Coating
  • Degassing/curing – oil, epoxy resin
  • Distillation/extraction/filtration
  • Freeze drying
  • Furnaces
  • Gas bottle filling/emptying
  • Gel drying
  • Glove boxes, ovens
  • Laboratory bench top vacuum
  • Leak detectors, Helium
  • Load locks and transfer chambers
  • Refrigeration manufacture
  • Research and development
  • Rotary, centirfugal evaporators
  • Scanning electron microscopes – SEM
  • SEM/FIB (ion beam repair)
  • Solvent recovery
  • Surface science instruments
  • Turbomolecuar backing pumps
