State-of-the-Art MacroTorr® Technology
The most effective pumping stage technology currently available.
Thanks to this powerful Varian innovation you can:
- maximize the throughput of the pump
- extend the foreline tolerance up to 18 mbar
-increase the compression ratio by decades, most notably for light gases without compromising the size or weight
of the pump. In fact, the MacroTorr® stages set in the V301 Navigator is hosted in the space of one inch.
Designed for Very High Gas Load Operation
Varian has been always focused on high throughput applications. Thanks to state-of-the-art numerical
modeling tools, pumping stages are designed to minimize the power consumption.
Special care is given to the thermal design of the cooling fins and the internal temperature distribution,
to ensure efficient operation.
Monolithic Rotor
Our patented cutting tools and EDM process, combined with a sophisticated CAD/CAM manufacturing operation,
allow Varian to produce pump rotors from a single piece of high tech aluminum alloy. This major technological
achievement improves the life of the pump for different reasons:
- the weight of the rotor is minimized, allowing installation of the pump in absolutely any position without
compromising the pump performance
- the lighter the pump structure, the lower the stresses on the material and on the bearings themselves,
resulting in longer pump life!
Highly Reliable, Maintenance-Free Ceramic Ball Bearings
No oil, no refill, no contamination. This is our design philosophy. All of our pumps are designed around
ceramic ball bearing technology.
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. The lubrication of the bearings is
critical. After years of research Varian has developed its proprietary Dry Lubrication technology to
guarantee excellent pump life time in any position and in any gas load working condition. Thanks to
ceramic bearings and Dry Lubrication technology, you can count on an ultimate MTTF of our products of
120,000 h plus. Thanks to Varian, performance has never been so reliable.
