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 RV8 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 RV8 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 RV8 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 RV8 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.

Providing long term reliability, these pumps have become the industry standard in range of scientific and laboratory applications, and the ideal partner for your tubomolecular pump.The drive is provided through and Oldham coupling by a single phase motor. The motor is totally enclosed and cooled by the motor-cooling fan which directs the air along the motor fins. A thermal overload devise is fitted to the motor which switches off the pump if the motor gets too hot, this will automatically reset when the motor cools down and restarts the pump.
