Edwards, Dual Stage, Rotary Vane Vacuum Pumps

RV5 Rotary Vane Vacuum Pump
RV8 Rotary Vane Vacuum Pump

To meet your demands for high throughputs with high ultimate vacuum BOC Edwards have developed a totally new concept in vacuum pumps - the world's first dual-mode vacuum pump.

This radical operation is matched by innovative design features such as a pumping mechanism incorporating advanced new materials, a fully-featured BOC Edwards motor and the incorporation of a fast-acting inlet valve to seal the pump for suck-back protection.

In addition, BOC Edwards extensive research into drive train and motor noise mean the RV series also delivers a high performance pump with a broad performance envelope that's quiet to live with and easy to maintain. – 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 unrivaled 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. 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.
