AGILENT VARIAN TV-301 NAVIGATOR TURBOMOLECULAR VACUUM PUMP are widely used in high energy physics, fusion technology, general UHV research, synchrotron light sources, particle accelerator rings, and fusion reactors and needed in extremely clean, reliable and cost effective high- and ultra high-vacuum applications

AGILENT VARIAN TV-301 NAVIGATOR Features and Benefits

Wide Pumping Speed Range: 70 to 6,000 l/s

Varian offers a complete range of turbomolecular pumps, to cover all possible applications and market segments.

High Speed, High Compression

Maximizing performance at minimum cost and size: this is our design mission. Our use of technology ensures maximum performance without compromising pump size, cost, or reliability. We use our technologies to meet the mainstream of our customers' applications, providing them with high performance, reliable pumping solutions at a competitive cost.

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.

Controller "Plug & Pump" Ready-to-Use T-plus SW

Operating and controlling a turbomolecular pump has never been so simple. Thanks to our T-plus Software you can connect your laptop directly to the pump control unit and start to use it. You can start or stop the pump, as well as check its temperature and gas load conditions. You can also monitor pump parameters over time, as well as do straightforward diagnostics directly on the vacuum system with a click of the mouse in the Windows based environment. From buttons to charts to dialoggers, everything is simple in our T-plus Software.

Very High Foreline Tolerance

Working with a foreline pressure as high as 18 mbar yields a substantial advantage: the size of the primary pump can be significantly reduced such that even a backing pump as small as the 5 m3/hr SH-100 (dry) or DS 102 can be used to operate our V 301 Navigator in all its pumping profiles. Thanks to one of the features of the MacroTorr® technology you can now reduce the cost of your vacuum system and get better performance at the same time.

Turbo-V Pump Typical Applications


The turbo pump is the critical element in the creation of an appropriate environment in the world of semiconductor manufacturing. In fact, as semiconductor chip geometries continue to shrink, the reliance on turbo pump technology is the highest it has been in the history of semiconductor manufacturing. Varian's turbo pumps provide unique and critical advantages in the creation of vacuum for the manufacture of semiconductor devices. Varian's rich history of innovations includes the pioneering of thermally stable ceramic bearings in place of stainless steel bearings, and the development of MacroTorr® turbo stages, among others.

The use of ceramic bearing technology allows Varian to run its turbo pumps at the one of the highest rotational speeds in the industry, providing high pumping speed for light gases like helium and hydrogen, which are frequently liberated in the production of semiconductors. Since pumping speed is directly related to rotational speed, our turbo pumps provide improved pumping speed in a more compact package.

Another critical innovation by Varian in the world of turbo pumps has been the introduction of the monolithic rotor in conjunction with MacroTorr® turbo stages. These two additions provide the turbo pump with the ability to meet demanding rapid cycle applications, such as vacuum load locks, in which high gas-load cycling and high tolerable foreline pressures are critical to the success of the process. Varian's turbo pump capabilities are unique, and the most advanced in the industry, allowing the user to share a single roughing pump across multiple turbo pumps, thus reducing costs and improving tool reliability by reducing the number of dynamic systems within the process tool.

High Energy Physics and Research Laboratories

Turbomolecular pumps are widely used in High Energy Physics, Fusion Technology and general UHV research. Synchrotron Light Sources, Particle Accelerator Rings, UHV Laboratory research, and Fusion reactors need extremely clean, reliable and cost effective HV and UHV.

Maintenance-free pumps are specifically required, because most pumps are not easily accessible.

Varian Turbo-V pumps are designed to offer unmatched reliability, performance and cleanliness for these applications. Ceramic bearing pumps, thanks to their reduced rolling friction, low stress and high thermal stability compared to conventional bearings, deliver longer operating life. Ultra low vapor pressure solid lubricant eliminates the need for maintenance and assures clean operation under any operating conditions.

Furthermore, in contrast to most of the other pumps, all Varian Turbo-V pumps have both the upper and the lower bearing in the rough vacuum side and not exposed to UHV, further reducing the possibility of contamination - even in case of misuse.

The patented MacroTorr® stages provide the highest speed and compression ratio in the smallest footprint; furthermore all the Turbo-V pumps can truly be mounted in any orientation, from vertical to horizontal to upside down, aiding system design in the most stringent space requirements. MacroTorr® Turbo Pumps can operate at higher foreline pressures, allowing the use of diaphragm roughing pumps, thus providing a completely clean, oil-free compact and cost effective pumping package.

Whenever a large amount of gas has to be pumped and higher throughput is needed, the combination of Turbo-V pumps and TriScroll® dry pumps is the state-of-the-art solution. All the Turbo-V Navigator pumps have the option of an on board controller, allowing easy plug and pump operation, or a rack-mounted controller for applications where the electronics need to be remotely placed (i.e. radioactive environments).

Analytical Instrumentation

Electron Microscopy (SEM, TEM), Focused Ion-beam Systems (FIB) and Surface Analysis

Modern focused-beam systems such as SEM's, TEM's and FIB's utilize columns that project electrons or ions onto microscopic samples for detailed analysis. End users analyze all types of substances from organic compounds to semiconductor wafers. In the Semiconductor industry, in particular, they require more sensitivity for better sample resolution. Another key requirement is high sample throughput in order to lower the cost of ownership of these instruments.

Based on these requirements, the demand for high performance vacuum pumps is greater than ever. Varian offers a full range of high and ultra-high vacuum pumps designed especially for the demanding requirements of SEM's, TEM's and surface analysis systems (Varian has a full range of ion pumps, which are key products for this application; please see ion pump section).

Turbo molecular pumps are also a key component in modern focused-beam systems because they offer fast, oil-free air evacuation of large sample chambers (oil-free operation is a key requirement of many modern analysis applications such as semiconductor manufacturing). From Varian's full range of turbo pumps, the focused-beam system designer can choose a pump size that offers the best chamber evacuation time with the best cost of ownership and compact size for use in limited space situations. Varian has a full line of customized, low vibration turbo pumps for the most sensitive microscopy applications.
