Agilent Vacuum Products Division (VPD), formerly Varian Vacuum, is a global supplier with a complete range of vacuum pumps, leak detectors,
components and accessories to create, control, maintain and measure vacuum. We have always been in the forefront of vacuum technology,
setting industry standards from the very beginning with the invention of the ion pump in the late 1950s that made UHV possible.
Major developments in diffusion pump and leak detection technology soon followed, with innovations in turbomolecular
and dry scroll pumping, up to the most recent revolutionary TwisTorr FS turbo pump and IDP-15 dry scroll pump.
products: Turbomolecular Pumps
Agilent Turbomolecular Pumps are designed for reliability and optimum performance in the most demanding research, industrial and analytical applications.
The Agilent TwisTorr Family, including 84FS and 304FS pumps, is our most recent innovative high-vacuum pump platform.
The platform combines TwisTorr drag stage technology and Agilent Floating Suspension.
TwisTorr drag stages create high compression ratios for light gases such as hydrogen and helium and deliver high throughput
and high foreline pressure tolerance, letting you use smaller and more economical backing pumps.
The Agilent Floating Suspension system reduces noise and vibration, ensuring optimal bearing operating conditions to minimize system downtime and safeguard stability.

Pfeiffer Vacuum is a vacuum technology world leader for more than 120 years:
an important milestone was the invention of the turbopump in our company more than 50 years ago.
Our comprehensive range of solutions, products and services includes vacuum pumps, measurement and analysis equipment, up to complex vacuum systems.

Pfeiffer Vacuum turbopumps are available for pumping speeds of between 10 and 2,700 liters per second.
These pumps will win you over with their high cost-efficiency and flexibility. Pfeiffer Vacuum turbopumps with their optimized reliability
use proven bearing systems which are available in two different options - a hybrid bearing system with a combination of a ceramic ball bearing
on the forevacuum side and a permanently magnetic radial bearing on the high vacuum side, and a fully, active magnetic bearing system in which
the rotor is levitated with no contact or wear at all.
Thanks to the sophisticated rotor design, extremely high pumping speed, critical backing pressure and gas throughput values are achieved as well
as very good compression values for light gases.
