Edwards RV8 6.9 CFM Dual-Stage Vacuum Pump with Bellow & Fitting Online Sale

Technology

All 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.
 
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.
 
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.
