Description
This refurbished Edwards 3.0 vacuum pump is tested and serviced. It is in a good state (see pressure readout and report) and will be delivered with new oil. These small oil sealed rotary vane pumps deliver excellent ultimate vacuum pressure, high pumping speeds and superior vapour handling capabilities with quiet operation. With 400,000 units produced, these pumps offer proven performance that sets the industry standard for R&D and scientific pumping applications.offers an excellent ultimate pumping speed.
Edwards pumps are relatively quiet and noise levels of 48 dBA 50Hz have been achieved by extensive work on the pump design, drive train and motor.
The pumps have the unique ability to deliver excellent 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.
In 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..
