Description

Edwards’ nES family of pumps includes advanced single-stage oil vane rotary pumps. The mechanism has been improved to provide better vacuum quality. The operating pressure range has been expanded giving unparalleled ultimate vacuum levels. Vacuum performance is stable without pressure fluctuations, a symptom often found in single-stage pumps. Extended service intervals and easy internal maintenance make the ES series a great fit as a flexible vacuum solution for a wide range of industrial applications. They can be used alone or with mechanical booster pumps to increase both efficiency and the ultimate vacuum level achieved.

Specification

Enhanced performance – extended operating pressure range and class-leading highest vacuum level
Stability – stable vacuum performance with no pressure fluctuations
Convenience – ISO / BSP thread, easy on-site serviceability
Flexibility – stand-alone operation or with a mechanical booster pump
Ease and simplicity – full kit with EH mechanical booster pump fits a wide range of applications
