Leybold Releases Faster and More Robust Turbomolecular Pumps

By Chris Tempas, Ph.D


Leybold, the world’s oldest vacuum pump manufacturer, has expanded its line of modern turbomolecular pumps to higher pumping speeds of 1350 and 1450 l/s. As a result, the new TURBOVAC 1350 i/iX and TURBOVAC 1450 i/iX can now reach even more industrial and scientific applications than ever before. 

Leybold is a premier manufacturer of vacuum pumps for industrial and scientific purposes. We are proud of our expertise in creating solutions and solving problems for our customers. We built this reputation by making industry-leading products of the highest quality coupled with extensive service options to ensure you get longevity out of our equipment. 

Our highly versatile TURBOVAC i/iX turbomolecular pumps will fit your needs whether you need them in the academic, research and development, analytical, life sciences, or industrial sectors. The pump comes in many variants — ranging from 90 to 1390 l/s pumping speeds. In addition, we have the accessories to tailor our machines to your process, offering the best performance. 

The new TURBOVACs are robust and built to improve your productivity and system uptime. With a user-friendly setup and operation, our products prove to be reliable and consistent, withstanding mechanical impact and harsh venting. This offers light gas pumping speeds of up to 60% above present reference products. In addition, compression values can be 100 times higher than previous generation products. 


For heavier gases (such as Ar), the TURBOVAC 1450 i is 10% higher than the present reference products. The pumps offer high throughput with high fore-vacuum pressures of up to 4 mbar. The new TURBOVAC models are available in DN 200 or DN 250 flange sizes. 

What does all this mean for you? Faster cycle times, higher process throughputs, and lower cost of ownership.

Setup is more accessible now with our new, simplified smart systems.

These intelligent systems check the condition of the mechanical bearing and warn when a service is imminent. The TURBOVAC 1450 i comes in standard and U variants — which you install in any orientation. 

Our next-generation software Leyassist efficiently runs all TURBOVAC models, enabling continual setting up and monitoring of operations. Our Product Manager Cormac Kerins states, “With Leyassist, we now offer a state-of-the-art intuitive software platform which is free to use for all our customers.”

TURBOVAC iX fits easily into your systems and can control the fore-vacuum pump and up to two sensors/gauges. Our products offer the universal “Anybus” via interface options via the Anybus module (RS232, RS485, ProfiBUS, ProfiNET, Ethernet, EtherCAT, etc.) for the full spectrum of field bus support. 

We have an oil-free hybrid bearing concept with a magnetically levitated upper bearing and lifetime-lubricated lower ball bearings

Our low vibration design reduces noise, stress, and other negative impacts on vibration-sensitive applications.

With these variants, the TURBOVAC i/iX series is now complete with 8 models ranging from 90 to 1450 l/s.

About Chris Tempas, Ph.D

Chris Tempas, Ph.D
Chris Tempas holds a Ph.D. in Chemistry from Indiana University. After receiving his B.S. degree in Chemistry from Michigan State University, Chris went on to a doctoral program at Indiana University, where his interest in vacuum got started. Hands-on learning with roughing pumps, turbomolecular pumps, Ion pumps, and gauges propelled Chris' knowledge of vacuum science and maintaining ultra high-vacuum. Recently promoted to Product Sales Development Manager, Chris now has the responsibility of specific ultra-high vacuum product lines within Leybold. This new role will allow more of a customer focus to overcome challenges and solve problems while teaching customers about vacuum technology. In his free time, Chris enjoys a good book (science fiction and fantasy), watching moves, playing video games, or simply spending time with family.
