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.
nEXT730
With the nEXT730 Turbomolecular Pumps, Edwards offers a larger pump that pumps nitrogen at a rate of 730 l/s.
Features and Benefits
Upper magnetic bearing - ensures clean vacuum, low power and low vibration.
Optimized rotor designs - deliver high speeds and high compression.
Different variants that are suitable for many applications - D = standard variant of the nEXT pump, H = optimized rotor design for high light gas compression and T = additional regeneration stage for increased compression and higher back pressure
Integrated Controller/Electronics - provides direct I/O or serial control or can be connected to one of our TAG or TIC controllers to facilitate systemization.
Fully user serviceable - oil cartridge and bearings can be changed in the field with minimal tools.
