Agilent Turbo Pumps

Agilent Turbo Pumps for High and Ultra-High Vacuum

Turbomolecular pumps are the workhorses of modern vacuum, and Agilent's TwisTorr and Turbo-V lines are among the most trusted in the field. These pumps spin high-speed rotor blades to knock gas molecules toward the exhaust, producing clean high and ultra-high vacuum with no pumping fluid anywhere in the vacuum path. Add fast start-up times and a compact footprint, and it is easy to see why turbo pumps sit at the center of so many analytical, semiconductor, and research systems.

Provac stocks new and rebuilt Agilent turbo pumps, and we back them with full bearing-rebuild and repair service that restores tired pumps to their rated performance. Whether you are outfitting a new instrument or bringing an old pump back to life, we can help you get there.

How a Turbo Pump Works

The idea behind a turbomolecular pump is beautifully direct. A stack of angled rotor blades spins at very high speed, and as gas molecules drift into the pump, the blades strike them and drive them downward through matching stationary blades toward the exhaust. Because the pumping action comes purely from mechanical momentum transfer, there is no oil or fluid in the vacuum path to contaminate your chamber.

That clean operation is a big reason turbo pumps have largely replaced older technologies in applications that cannot tolerate contamination. The tradeoff is that the rotor spins extremely fast and rides on precision bearings, which means bearing condition is everything. When bearings wear, the pump needs a rebuild, and a proper rebuild returns it to full performance.

The TwisTorr and Turbo-V Series

Agilent builds turbo pumps in two well-known families, each with its own strengths. Provac stocks and services both:

•    TwisTorr pumps use Agilent's advanced molecular-drag stages, which give better performance at higher foreline pressures and make backing easier

•    Turbo-V pumps are the proven, versatile choice across a wide range of pumping speeds and applications

•    Both are available with a range of rotor-mount and inlet options to fit your flange and orientation

Where Turbo Pumps Are Used

Turbo pumps show up almost anywhere clean high vacuum is needed. Common applications include:

•    Mass spectrometry and analytical instrumentation

•    Semiconductor processing and metrology

•    Surface science and electron microscopy

•    Research and ultra-high vacuum systems of every kind

Building a Complete Vacuum System

A turbo pump is powerful, but it never works alone. It needs two partners to do its job. First, it needs a matched Agilent turbo pump controller to spin it up, regulate its speed, and protect it against faults. Second, it needs a backing pump, and a dry Agilent scroll pump is the natural choice because it keeps the whole system oil-free from the foreline up. Together, those three parts form a clean, reliable high vacuum stack.

If you would rather not assemble the pieces yourself, Provac's Agilent pumping stations bundle the turbo pump, the backing pump, and the controller into one tested, ready-to-run system. And when your process needs to reach and hold ultra-high vacuum, you can add an Agilent ion pump to take over once the turbo has brought the chamber to base pressure. We can help you plan out the entire chain so every stage is sized correctly.

Repair and Rebuild at Provac

Turbo pumps reward good maintenance, and a well-rebuilt pump can serve for many more years. Provac's rebuild service is thorough, because with a rotor spinning this fast, precision is not optional. Every rebuild is balanced and tested before it comes back to you.

•    Bearing and rotor rebuilds returned to factory tolerances

•    Careful balancing and full testing before shipment

•    New and rebuilt inventory ready to ship

•    A warranty on rebuilt units so you are protected

Bearing Types and What They Mean for You

Turbo pumps use different bearing designs, and the type in your pump affects how it is maintained. Some pumps use mechanical ball bearings, which are proven and serviceable and are rebuilt on a schedule as they wear. Others use magnetic bearings, which levitate the rotor with no physical contact and so avoid that wear entirely, at a higher up-front cost. Neither is simply better than the other, since the right choice depends on your application, your tolerance for maintenance, and your budget. What matters most is that whichever bearing your pump uses, Provac can service it, and we can advise you on the tradeoffs if you are choosing a pump for a new system.

Getting the Longest Life From Your Turbo Pump

A turbo pump rewards a little care with many years of service. Running the pump within its rated foreline pressure, giving it a properly sized backing pump, and venting it gently rather than slamming it to atmosphere all extend bearing life and protect the rotor. Keeping the cooling in good order matters too, since heat is the enemy of a fast-spinning rotor. When bearings do reach the end of their life, catching it early and rebuilding the pump promptly prevents a small wear problem from becoming a catastrophic failure. Our rebuild service is built around exactly this kind of preventive care, returning pumps to factory tolerances before trouble sets in.

Frequently Asked Questions

How do I choose between TwisTorr and Turbo-V? It depends on your foreline pressure needs and application. Tell us about your system and we will recommend the better fit.

Can you rebuild my worn turbo pump? Yes. We rebuild bearings and rotors to factory tolerances, then balance and test the pump before returning it.

What else do I need besides the turbo pump? A matched controller and a backing pump, usually a dry scroll pump. We can supply the whole set.

Matching a Turbo Pump to Your Application

Sizing a turbo pump well is about more than picking the biggest one you can afford. The right pump matches its pumping speed to your chamber volume and gas load, mounts in the orientation your system needs, and connects through a flange that fits your hardware. An oversized pump wastes money and may be harder to back, while an undersized pump will struggle to reach or hold your target pressure. This is where a conversation with a specialist pays off. Tell us about your chamber, your process, and the pressure you need, and we will point you to the TwisTorr or Turbo-V model that fits, along with the controller and backing pump that complete the system. Getting this match right the first time saves both money and frustration down the road.

One Source for the Whole Vacuum Chain

A turbo pump is only as good as the system around it, and Provac stocks and services that entire system. From the dry scroll pump that backs the turbo, to the controller that drives it, to the ion pump that can hold ultra-high vacuum once you are at base pressure, we can supply and support every stage. That means you have one team to call for sales, sizing, and service rather than a different vendor for each component. For a fast-spinning, precision tool like a turbo pump, having experienced people behind it is worth a great deal.

Why Buy Your Turbo Pump From Provac

Choosing and maintaining a turbo pump is easier when the people selling it actually rebuild these pumps by hand. Provac's decades of experience mean we can help you pick the right TwisTorr or Turbo-V for your instrument, match it to the correct controller and backing pump, and support it long after the sale.
