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. 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 vapour pumps, solvent concentration, freeze drying and other drying applications. They 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.

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.

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.

Applications:

Analytical instruments
Centrifuges, ultra-high speed
Coating
Degassing/curing – oil, epoxy resin
