Edwards RV pumps have become the industry standard for scientific primary pumping applications. RV pumps are uniquely capable of delivering high or low throughput 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 pumps are approved to UL and CSA standards by an external test house. Edwards has a global network, providing world-wide support for product applications and service.

Supplied with: 1 litre of Ultragrade 19 oil, inlet filter and O-ring. Free KF25 flexible stainless steel bellow (3.3 ft), clamps and centering rings set included for immediately use (mist filter NOT included). Fomblin® must be purchased separately for PFPE RV pumps.Technical support and one year warranty covered by Edwards.


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 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, 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.
