Designed for long-term reliability and minimal maintenance needs

nEXT turbomolecular pumps are hybrid bearing pumps with integrated controllers for pumping speeds from 47 to 1250 ls-1.

The nEXT is a hybrid bearing compound turbomolecular pump. nEXT pumps combine our proven bearing technology (oil lubricated ceramic lower bearing with dry permanent magnetic upper bearing), an improved rotor design with a new molecular drag stage to deliver improved pumping speed and compression ratios, and user serviceability. They feature 24 V to 48 V DC sensorless motors with a built-in drive that is fully compatible with our range of TAG and TIC controllers.

Features and Benefits

Upper magnetic bearing - ensures clean vacuum, low power and low vibration.
Optimised rotor designs - deliver high speeds and high compression.
Range of variants suitable for many applications - D = standard nEXT pump variant, H = optimised rotor design for high light gas compression and T = additional regenerative stage for increased compression and higher backing pressure capability
Integrated controller / electronics - offers direct I/O or serial control or can be connected to one of our TAG or TIC controllers for easy systemisation.
Fully user serviceable - oil cartridge and bearings can be changed in the field with minimal tooling.
Inlet screen - supplied as standard
