series of rotary vane pumps are 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.
rugged vacuum pumps offer an excellent ultimate with good pumping speeds as
well as superior vapour 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.
WET PUMPING APPLICATIONS
CLEAN DRY APPLICATIONS
SPECIAL APPLICATIONSWhere 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:
Key benefits of Edwards RV pumps for “wet” applications:
For applications where the solvents/vapours 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.DUSTYKey benefits of Edwards RV pumps for “dusty” applications
Designed using experience of PVD and CVD applications from the semiconductor industry, Edwards range of RV pumps are ideal for dusty applications.CLEAN/DRYKey benefits of Edwards RV pumps for clean/dry applications
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.
OXIDANTSKey benefits of Edwards RV pumps for pumping oxidants:
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.
Edwards range of rugged vacuum pumps offer an excellent ultimate with good pumping speeds. RV pumps also have superior vapour handling capabilities while operating quietly.
