Edwards Vacuum

The Edwards RV12 vacuum pump delivers excellent ultimate vacuum pressure, high pumping speeds and superior vapor handling capabilities with quiet operation. With over 300,000 units produced, these pumps offer proven performance that sets the industry standard for R&D and scientific pumping applications. All RV pumps are approved to UL and CSA standards by an external test house and feature our unique mode selector switch, meaning one model is suitable for both high vacuum or high throughput applications. In summary, you can rest assured that when you choose an Edwards RV oil sealed rotary vane pump you are choosing a product you can rely on from a company you can trust.Supplied with: 1 litre of Ultragrade 19 oil, inlet filter and O-ring. Fomblin® must be purchased separately for PFPE RV pumps. The Edwards RV12 series of small oil sealed rotary vane pumps deliver excellent ultimate vacuum pressure, high pumping speeds and superior vapor handling capabilities with quiet operation.

All RV pumps are approved to UL and CSA standards by an external test house and feature our unique mode selector switch, meaning one model is suitable for both high vacuum or high throughput applications. In summary, you can rest assured that when you choose an Edwards RV5 vacuum pump you are choosing a product you can rely on from a company you can trust. The Edwards RV12 vacuum pump is the result of more than 75 years’ experience and a clean sheet design programme to produce the ultimate range of small oil sealed rotary vane pumps. These rugged vacuum pumps offer an excellent ultimate with good pumping speeds as well as superior vapor handling capabilities and quiet operation. Edwards RV series of vacuum pumps have become the industry standard with over 200,000 units sold. This success has been based on field proven design and reliability in a wide range of applications and environments. High Vapor Handling: Quicker Process Superior Particulate Handling: High Reliability Fast Acting, Dependable Inlet Valve for Anti-Suck Back Protection: Safe Process & Systems Mode Selector & Two Position Gas Ballast: Configured to Meet Your Vacuum Needs Designed for Easy Maintenance: No Unplanned Downtime Quiet Running: Better Work Environment Analytical instruments – LCMS Distillation Extraction Filtration Freeze drying Gel drying Solvent recovery Centrifugal evaporation DUSTY APPLICATIONS Furnaces De-gassing CLEAN DRY APPLICATIONS Analytical instruments – GCMS Centrifuges Coating Turbo pump backing Gas bottle filling/emptying Leak detectors Load locks Electron microscopes SPECIAL APPLICATIONS Where your application does not fall into one of the other categories, we can offer pumps specifically designed to meet your requirements. Past examples of these include: PFPE prepared pumps Versions compatible with brake fluid ATEX approved pumps Air driven motor variants for oil and gas rig Many of these variants have gone on to become standard catalogue items, so if you have an unusual application please ask your local salesman and we will be pleased to help KEY FEATURES AND BENEFITS WET PUMPING Key benefits of Edwards RV12 vacuum pump for “wet” applications: Highest vapor pumping capacity of any rotary vane pump Unique mode selector switch means pump maintains lubrication at high flow Highest gas ballast flow of any rotary vane pump giving 220g/hr (290g/hr on RV12) water vapor handling capacity Optional oil return kit to ensure the oil stays in the pump at high flow For applications where the solvents/vapors are incompatible with fluoroelastomer (FKM) seals, a nitrile (Buna-N) conversion kit is available. Additionally PFPE prepared pumps may be ordered if pumping large quantities of oxidants. DUSTY Key benefits of Edwards RV12 vacuum pump for “dusty” applications Best in class anti-suck back protection to prevent dust getting back into the process Controlled opening by oil pressure to eliminate pressure surge Rapid closing within 0.4 seconds of pump stopping due to dump valve Large diameter oil passages (3-5mm) to avoid clogging Some competitor pumps have oil passages of less than 1mm diameter Designed using experience of PVD and CVD applications from the semiconductor industry, Edwards range of RV pumps are ideal for dusty applications. CLEAN/DRY Key benefits of Edwards RV12 vacuum pump for clean/dry applications Unique mode selector switch means pump maintains lubrication at high flow Optional oil return kit to ensure the oil stays in the pump at high flow Best in class anti-suck back protection to prevent oil mist getting back into the process Controlled opening by oil pressure to eliminate pressure surge Rapid closing within 0.4 seconds of pump stopping due to dump valve The patented mode selector means that the pump is equally happy in either high vacuum applications or high throughput applications. For the latter an optional oil return kit can be fitted that allows the pump to operate continuously at high throughput without losing all its oil down the exhaust line. OXIDANTS Key benefits of Edwards RV12 vacuum pump for pumping oxidants: Highest gas ballast of any rotary vane pump Allows dilution of pumped gases to minimize oxidation of the oil PFPE variants available Ideal for pumping oxygen and halogenated compound The high gas ballast of the RV pumps allows higher flows of oxygen whilst maintaining dilution to below the lower explosive limit. When combined with the optional oil return kit to prevent the gas ballast from blowing all the oil into the exhaust and a PFPE prepared pump to avoid oxidation of the oil, the RV pump makes a solid pump for oxygen. Equally these same features make the RV pumps ideal for pumping other oxidants such as halogens and halogenated compounds. For these compounds fire/explosion is not an issue, but a gas ballast is still useful for dilution to protect the oil and bearings. PFPE should be used to prolong oil life.

The EXT75DX is a hybrid bearing compound turbo pump that combines the proven technology of a ceramic mechanical lower bearing, a dry permanent magnetic upper bearing and Holweck drag stage with the added convenience of an on-board 24V controller allowing parallel and serial communication compatible with our TAG and TIC controllers. It is available with either aDN40NW, ISO63, DN63CF or an ISO100 inlet flange with an N2 pumping speed of up to 66ls-1. A basic pump system would require an EXT75DX pump, a TAG or TIC controller, either an air or water cooling accessory and a suitable backing pump.
