1 year warranty.




Edwards RV pumps have become the industry standard for scientific primary pumping applications. RV pumps are uniquely capable of delivering high or low throughputs with high ultimate vacuum. This, combined with ultra-low noise levels, makes them ideal for a wide range of applications including GCMS and other small bench top type applications.

All our RV pumps are significantly quieter ¢ÛÒ 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.

      Edwards Pump Rebuld Process:

      Every Edwards vacuum pump we sell goes through our comprehensive rebuild process at our location!

        • Each pump is fully disassembled and all parts are cleaned and decontaminated with our multi-step process to ensure all contaminants are removed.

        • All parts are inspected for wear.

        • Damaged or worn parts are replaced.

        • All O-rings, seals, springs, gaskets replaced.

        • Motor tested.

        • Assembled and tested with multiple flushes of new oil.

      Our Rebuilt Edwards Vacuum Pumps comes with a full 1 year warranty for parts and labor.
