Overview

The Edwards nES single stage series represents the next advancement in oil sealed rotary vane vacuum pumps for use in a wide of range industries and applications.
Offering high reliability, low life cycle cost and proven performance, the nES series provides an ideal solution to suit a broad range of requirements.

Features and Benefits

Proven performance

The Edwards nES series deliversconsistent pumping performance with excellent vacuum stability. High pumpingspeed at low pressures with good condensable vapour handling capabilityprovides an ideal solution for a range of applications.

 

High reliability

The pump mechanism provides highreliability ensuring maximum productivity. Engineered with high qualitycomponents, an effective oil return system and integrated mist filter, the nESseries is designed to maximise process efficiency.

 

Low lifecycle cost

Efficient cooled motors, optimised oilretention, low pump temperatures, high reliability and minimum maintenanceprovides excellent lifecycle cost compared to other single stage rotary vanepumps.

 

Compact and clean

The nES series is both robust and compactin design. In addition, low noise and vibration minimises environmental impact.
