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.

The EM range of oil?sealed rotary pumps renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour have become the industry standard for laboratory and light industrial applications. The pump is a freestanding unit with the drive provided through a flexible coupling by either a single phase or three phase (four pole) motor.Each EM pump is supplied with 1 litre of Ultragrade 19 oil, O ring and centering ring, two Allen keys and spares seal for oil drain and filter plugs. For PFPE prepared FX pumps Fomblin® to be ordered separately.

E2M0.7 and E2M1.5 two stage oil sealed rotary vane pumps are renowned for achieving high ultimate vacuum and rapid pumping speeds, with quiet operation and compact size. 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.
