Power Requirements: 963 Hz, 90 V to 250 V?
With more than 50 years of experience in vacuum science, Varian, Inc. leads the way in developing unique design solutions. Many of these innovations are present in Varian's Turbo-V turbomolecular pumps:
Varian's design mission is to maximize performance at minimum cost and size.
This is the most effective turbo-pumping technology available. Thanks to the powerful MacroTorr innovation you can:
* maximize the throughput of the pump
* work with foreline pressures as high as 18 mbar
* increase the compression ratio by decades, most notably for light gases
* keep the size and weight of the pump to a minimum
Very high gas-load capabilities:
Thanks to our state-of-the-art numerical modeling tools, the turbo pumping stages are designed to minimize power consumption. Special care is given to the thermal design of the cooling fins and the internal temperature distribution to ensure efficient operation.
Varian, Inc. produces each pump rotor from a single piece of high-tech aluminum alloy. This major technological achievement improves the life of the pump for several reasons:
* Rotor weight is minimized.
* Stresses on the bearings are reduced.
Highly reliable, maintenance-free ceramic bearings:
These bearings need no lubrication, which means no oil, no refills, and no contamination. Ceramic is lighter, harder, smoother, and thermally more stable than any steel. So, a ceramic-ball bearing can run faster, hotter, and more quietly than any steel-ball bearing. Performance has never been so trouble-free.
