A turbomolecular pump is a type of high vacuum pump. These pumps create a vacuum by giving gas molecules momentum by repeated collision with a rapidly spinning turbine rotor. The rotor blades collide with gas molecules from the inlet of the pump which propels them towards the exhaust in order to create or maintain a state of low pressure (a vacuum).
Turbopumps are ideal for scientific and R&D applications including mass spectrometry, solar research, thin film coating and more. Industrial applications include the manufacture of micro-electronics (semiconducting) and renewable energy applications.
Edwards vacuum introduces the nEXT generation of turbomolecular pumping technology. Built upon more than ten years of experience with the reliable EXT and STP ranges of turbos (with over of 200,000 turbos in the field today), the nEXT sets the new global benchmark for scientific turbopumps.
The nEXT turbos are truly user-serviceable, featuring a user replaceable oil lubricated ceramic ball bearing and a replaceable oil-cartridge.
The Edwards EXT turbomolecular pumps provide a stable and reliable, hydrocarbon-free high and/or ultra high vacuum. The EXT uses multiple-stage axial flow turbines and both magnetic and ceramic bearings. The EXT range of turbos guarantee an oil-less and vibration free operation and offer minimal maintenance on high critical foreline pressure processes.
The STP range of turbomolecular pumps are a magnetically levitated turbopump which provides high-up time, hydrocarbon free pumping. The multiple-axis magnetic bearing design suspends the rotor during operation, eliminating the risk of contamination while minimizing noise, vibration, and maintenance requirements due to reduced ‘touching’ of the internals of the pump. The STP pumps are fully interfaceable with advanced controllers.
