The nES EX series single stage rotary vane vacuum pumps, launched by Edwards in 2018, has proven to be the next advancement in oil sealed rotary vane pump technology suitable for use in explosive environments.

The nES EX series are specifically designed to be capable of handling flammable gases and are ideally suited to operate in environments where a potentially explosive atmosphere can be present, especially in chemical processing industries.

“The nES EX offered a response to increasing customer demand for a stable, safe and compact vacuum pump that is low on maintenance and high on productivity”, said Sylvain Turc, Product Manager, Edwards. “Motorised pumps are certified to ATEX directive 2014/34/EU and we have bare shaft pumps available for local configuration to support North America and other global markets.”

Available in six variants, the nES EX 40-630 series’ pump mechanism is designed with attention to detail that guarantees a class-leading ultimate vacuum level without pressure fluctuations. A variety of sensors on the pump offer easy readings for pump temperature, exhaust back- pressure and oil levels. While they are suitable for a wide range of industries including pharmaceutical, automotive and degassing, they are particularly suited to the demanding applications in the chemical processing industries.

“The nES EX series gives us the ability to serve a wide range of applications with a competitive edge in the chemical sector,” said Sylvain Turc, Product Manager, Edwards. “It is also in line with our brand promise to enable environments where innovation thrives. The nES EX series is a perfect example of our commitment and long-term responsibility to our customers, their work environment and the people who operate our products,” he continued.
