EM Series pumps | EM Oil Sealed Rotary Vane Pumps 
Edwards‘ EM Series pumps are rugged, mechanical oil-sealed pumps in a compact and quiet design. Small EM oil-sealed rotary vane pumps are renowned for achieving high ultimate vacuum and rapid pumping speeds with quiet operation and the ability to handle vapour. These pumps have become the industry standard in a range of scientific, laboratory, and light industrial applications, and are the ideal partner for backing your turbomolecular pump.
EM Series Pumps overview
- Quiet operation: For a better working environment.
- Flexibility of use: Freestanding unit compact design.
- Reliable performance: Proven in a range of laboratory and industrial applications over many years.
- Gas ballast valve: Used when pumping vapour.
- Built-in protection systems: The motor is enclosed and cooled by the motor-cooling fan which directs the air along the motor fins. Overheating protection is provided via a thermal overload device which is fitted in the motor and switches off the pump if it gets too hot, this will automatically reset when the motor cools down and restarts the pump. No manual intervention is required.
- Easy to maintain: The O-ring sealed sight glass makes visual inspection of the oil level and conditions simple. The oil drain port is located at the end of the oil box for draining oil out of the pump. A large oil filling port and recess in the top of the oil box top makes oil top-ups easy.

RV Two Stage Rotary Vane Pumps
Edwards RV series of vacuum pumps have become the industry standard with over 400,000 units sold. This success has been based on field-proven design and reliability in a wide range of scientific and laboratory applications and environments.
RV pumps are configured to meet your vacuum needs with a mode selector and 2-position gas ballast that allows either 60 g/hr or a class-leading 220 g/hr (290 g/hr on RV12) of water vapour to be handled. This is ideally suited for your wet pumping applications such as freeze drying, extraction, filtration and gel drying.
These multi-purpose pumps are extremely versatile and perfect for many applications. For safe processes and systems, the built-in anti-suck back protection prevents oil mist from entering your system. The rapid closing inlet valve acts within 0.4 seconds of the pump stopping, providing reliable and safe operation in almost any application and thanks to the use of wide range motors the pump covers a wide range of possible voltage and frequency from two motor variants.
We can also offer an RV to meet your specific requirements including PFPE-prepared and ATEX-approved pumps.
Easy to maintain: the O-ring sealed sight glass makes visual inspection of the oil level and condition simple. The oil drain port is located at the end of the oil box for draining oil out of the pump. A large oil filling port and recess at the top of the oil box top make oil top-ups easy.
RV series overview
- Unique mode selection switch: enables high vacuum and high throughput operation from a single pump
- Single-phase and three-phase motor options that meet the requirements of the IE2 efficiency rating.
- Low noise: from just 48 dB(A)
- High gas ballast flow rate: for up to 220 gh-1 water vapour pumping capacity
- O ring sealed sight glass: allows visual inspection of the oil level and oil condition
- High quality oils: with additives to prolong life whilst not impacting vapour pressure
- Forced air cooling: ensures low pump surface temperature
- Fast acting inlet valve: with controlled operating for system protection

nES | Single Stage Rotary Vane Pumps
Offering high reliability, low life cycle cost and proven performance, the Edwards nES single-stage series represents the next advance in oil sealed rotary vane vacuum pumps for use in a wide of range industries and applications.
nES Single Stage Rotary Vane Pumps Overview
- Optimised oil return system: The optimised oil return and separation system supports stable pumping performance and minimises oil loss.
- Low lifecycle cost: Efficient cooled motors, optimised oil retention, low pump temperatures, high reliability and minimum maintenance provide excellent lifecycle cost compared to other single stage rotary vane pumps.
A compact design with low maintenance
- The nES series is both robust and compact in design.
- Low noise levels and vibration minimise environmental impact.
- Easy to maintain and high productivity.
Flexible and systemisation-friendly
- The nES range is available with boosters and combination kits to enable you to build a complete systemised ready-to-use unit.
- Alternatively, combination kits, together with the nES pump and EH mechanical booster, are available as a kit of parts that allows for easy on-site assembly.
