    Edwards RV12 Two Stage Rotary Vane Vacuum Pump

    Edwards Small Pumps and Pumping Systems

    To meet the diverse needs of applications ranging from analytical instrumentation, wet chemistry, R & D to light industrial, IVS offers a comprehensive range of different Edwards pumping technologies.

    Easy to Service

    All Edwards pumps are designed for easy routine maintenance. Key components are easily accessible and, with RV and XDS pumps, no special tools are required. Service kits of guaranteed parts are available for routine service by the user. Worldwide support from the Edwards service organization is also available.

    Quality Manufacture

    Edwards pumps are manufactured on state of the art machine tools for high consistency of components. For example, RV rotors are manufactured in a robotic cell to remove errors and inconsistencies from the manufacturing process.


    Edwards high performance pumps are used in many industrial and laboratory applications, including the following:

    • Electron microscopes, mass spectrometry, residual gas analyzers and surface analysis
    • Epoxy degassing, powder materials processing
    • Solvent concentration
    • Sterilization, distillation and centrifuges
    • Gel dryers and glove boxes
    • Atomic emission spectrometers, nuclear physics, fusion technology and space research
    • Vacuum ovens
    • TV tube evacuation
    • Automotive system filling
    • Freeze drying
    • Vacuum metallurgy

    The Edwards RV series vacuum pumps allows the user to easily configure a unit to pump very high gas loads and achieve excellent vacuum..

    This is matched by design features such as a fully-featured Edwards motor and a fast-acting inlet valve to seal the pump for suck-back protection. The RV series delivers a high performance pump and broad performance envelope that's quiet and easy to maintain.

    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 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 liter of Ultragrade 19 oil, inlet filter and O-ring.

    Small Pumps and Accessories: Frequently Asked Questions

    Oil Mist

    Question: What accessory do I use to trap oil mist (which all oil sealed pumps emit during pump down or with gas ballast)?

    Answer: To meet regulations and preserve pump oil, fit a recommended Edwards oil mist filter (EMF) to the pump outlet, and connect the exhaust to an exhaust line.

    Question: If I operate an RV pump continuously or with high inlet pressure, what accessories do I need?

    Answer: Fit an Edwards mist filter (EMF) and a gas ballast oil return (GBOR) kit. Then the pump can be operated with the mode switch open and gas ballast oil return. The oil condensed in the filter will be continuously returned to the pump oil box.

    Vapor Processing

    Question: Which pump and accessories should I use if my process generates vapors which could condense in the pump?

    Answer: You can choose either an XDS pump, or rotary pump. Gas ballast should be used with both pumps; to sweep the vapor through the pump. This prevents condensation and oil contamination.

    Operate the pump with gas ballast for at least an hour before and after use. Choose the size of pump taking into account the vapor pumping rate.

    If you selected a rotary pump, then you should fit a gas ballast oil return kit and mist filter. Change the oil frequently and keep an oil change reminder tag on the pump.

    D-Lab would also be a suitable alternative depending on required pumping speed.

    Dust and Particle Processes

    Question: Which pump and accessory should I use if my process generates dust or grit, which could clog or damage the pump?

    Answer: Use a rotary pump fitted with an inlet dust filter. We do not recommend the use of scroll pumps or XDD1 pumps for these applications.

    Special Chemical Cleaning Processes

    Question: Which pump and accessory should I use if my process generates oxygen or ozone?

    Answer: Use a rotary pump adapted to run with Fomblin® oil or XDS. Contact Edwards for more information.

    Question: Are there any special considerations if my pump will be used in the vicinity of organic gases, like propane?

    Answer: Use a rotary pump fitted with a flameproof motor. Contact Edwards for more information.


    Question: Which pump and accessories should I use if I must ensure that my process and process chamber (operated below 0.1 mb) are not contaminated with oil from the pump?

    Answer: Use an XDS scroll pump.

    Alternatively, you can use a rotary pump with a FL20K foreline trap fitted to the system inlet. The trap contains activated alumina which traps the oil molecules. To maintain the alumina charge, bake the charge basket or replace as required.

    Question: How can I reduce the noise level of my pump?

    Answer: If the noise is only obvious during pumping down then fitting the exhaust with a silencer (XDS pumps), or fitting an exhaust line will reduce the level.

    An alternative is to fit an acoustic enclosure. Contact Edwards for more information.
