Edwards Dual-Mode RV Vacuum Pumps

These pumps allow high throughputs with low ultimate vacuum. 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. The mode selector (high vacuum or high-throughput) and three-position gas ballast control allow the pump to be reconfigured at any time, even when the pump is running. A fast-acting inlet valve seals the pump for suck-back protection. The pumps run at a quiet 48 dB. Before shipment each pump is tested in a quiet room using a noise spectrum analyzer. All controls are clearly marked and have large finger grips for ease of use. Inlet and outlet are both fitted with standard NW25 flanges. Ultimate vacuum will range from 1.5 x 10–3 to 7.5 x 10–2 torr (total pressure) depending on the operational mode selected. An oil sight glass is on the end of the pump. Complete with an on/off switch on the pump. 110 volt. Warranty: 1 year. CSA Approved.

In high vacuum mode Edwards RV is ideal for:
analytical instruments
electron microscopes
physics research
backing turbo pumps
TV tube pumping
mass spectrometer leak detectors

Simply reconfigured to high throughput mode the same pump becomes suitable for:
mass spectrometer inlet systems
distillation
laboratory furnaces
solvent concentration
freeze drying and other drying applications
backing vapour pumps
