nEXT turbomolecular pumps are hybrid bearing pumps with integrated electronics. We offer a wide range of pumping speeds from 47 to 1250 ls-1. nEXT pumps combine our proven bearing technology (oil-lubricated ceramic bearing with permanent magnetic top bearing), an improved rotor design with a new molecular compression stage to achieve improved pumping speed and compression ratio as well as better serviceability. They feature 24V to 48V DC sensorless motors with an integrated drive that is fully compatible with our TAG and TIC controllers.
nEXT85
With nEXT85 and nEXT55, Edwards offers a small and compact turbomolecular pump platform that is ideal for both analytical instrumentation and the R&D market.
Features and Benefits
Upper magnetic bearing - ensures clean vacuum, low power consumption and low vibration.
Optimized rotor designs - for high speeds and high compression.
Variety of variants for many applications - D = standard nEXT pump variant, H = optimized rotor design for high light gas compression and T = additional regeneration stage for increased compression and higher counterpressure capability
Integrated controller/electronics - provides direct I/O or serial control or can be controlled with one of our TAG or TIC controllers.
Fully user serviceable - oil reservoir and bearings can be changed in the field with minimal tools.
