nEXT turbomolecular pumps are hybrid bearing pumps with a compound drag stage and integrated controllers for pumping speeds from 47 to 400 l/s. They all feature a permanent magnetic upper bearing, which eliminates hydrocarbons at the top of the rotor and an oil lubricated lower bearing for reliable high speed operation.
The on-board controller interfaces directly with our TIC and TAG controllers to provide low cost system integration. The nEXT models also allow user serviceability by way of a user changeable bearing cartridge for low cost of ownership.
MULTIPLE DRAG STAGES
for higher compression ratios and geater backing pressure tolerance
PERMANENT MAGNET UPPER BEARING
for a hydrocarbon free vacuum, reduced vibration and minimum wear
SENSORLESS DRIVE
for high efficiency and compactness with reduced stray magnetic fields
VENTING
Manual vent port with automatic valve accessories for rapid venting and quick cycle times
PATENTED BEARING SUSPENSION
system that minimises noise and vibration transmitted to the vacuum system
FLEXIBLE CONTROL
simple parallel operation, sophisticated serial control, wide operating voltage range from 24V to 48V d.c.
