nES Single Stage Ex Series Rotary Vane

Primary Vacuum

Specifically designed to be capable of handling gases from a potentially explosive atmosphere and to operate in environments where potentially explosive atmospheres can be present. Pumps have been certified under the ATEX directive 2014/34/EU.

Superior performance

Deliver consistent pumping performance with excellent vacuum stability

High reliability

Designed to maximise process efficiency

Low lifecycle cost

Efficient cooled motors, optimised oil retention, low pump temperatures, high reliability and minimum maintenance

Compact and clean

Robust and compact design

Equipped with sensors to protect your pump

nES pumps are equipped with sensors to measure pump temperature, oil level and pressure in oil casing. They are also equipped with PTC motor thermistors for motor and overcurrent protection.

Internal mechanism designed for low temperatures

You are guaranteed a class-leading ultimate vacuum level without pressure fluctuations. The mechanism is designed to ensure minimal hotspots within the pump.

Ideal for a wide range of applications

If your application includes an explosive environment, the nES is the ideal pump. It is suitable for use in the chemical, pharmaceutical, degassing, automotive and gas vapour recovery industries. Edwards’ applications team can help you identify the ideal use of the nES pump for your application.

Equipped with ATEX compatible accessories
