 nEXT Sneak Preview:
 
Exceptional performance
 


At Edwards we understand the need for our vacuum pumps to deliver exceptional performance for our customers, in some of the most demanding applications. With this in mind we have developed the nEXT technology to maximise performance and deliver a new experience in turbopump serviceability.

Conventional turbopump rotors are designed to deliver either high speed or high compression. To eliminate this compromise the blade arrangements on the nEXT rotor have been totally re-designed to optimise pump performance and achieve both higher speeds and higher compression.

The end result is an exceptional class leading performance for a pump of its size.
