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.
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.
Field Proven Reliability:
Edwards are one of the largest producers of turbopumps in the world. Our STP pumps are the industry standard for magnetically levitated turbopumps and are the pump of choice in the most demanding of semiconductor applications. Equally our range of Scientific EXT and the new nEXT turbopumps are standard fit in many of the scientific instruments produced over the last two decades, combined this equates to over 200,000 pumps in the field.
In satisfying the performance and reliability requirements from the most demanding of customers, we are proud to have developed a strong reputation for our turbopumps amongst the top scientific instrument manufacturers in the world.
In buying an Edwards nEXT turbopump you can be certain that you are getting a pump based on field proven technology with a track record on reliability to match.
End User Serviceability:
The Edwards nEXT pumps are truly end user serviceable in just minutes…you can do it.
In a conventional turbopump, the bearing is supported both axially and radially by damping elastomers. While these provide some damping of rotor vibration such that it is not transmitted to the pump body, the characteristics of these can change in time leading to increased vibration levels.
The lower bearing on Edwards nEXT pumps is hard mounted into a special suspension system and the damping elastomers eliminated. This suspension system is designed to be stiff in the axial direction which ensures precise rotor positioning, but more compliant radially which absorbs vibration. These low vibration levels are maintained for the life of the pump.
When changing the pump bearing, the rotor does not need to be re-balanced enabling the end user to complete the service in the field without the use of complex tooling, jigs, fixtures or indeed major disassembly.
