VACUU·PURE 10Screw pump
for non-corrosive applications

The dry screw pump VACUU·PURE® 10 reliably delivers the benefits of oil-free vacuum technology in the pressure range down to 10-3 mbar. VACUU·PURE 10 combines three important benefits for the user: 100% oil-free, no abrasion, and no wear parts.

VACUU·PURE 10 is ideal for clean processes which require a dry and hydrocarbon-free vacuum. The spindles of the screw pump run contact-free and are thus free of abrasion and wear. The screw pump is especially designed for processes in the vacuum range down to 10-3 mbar, however unlike other fine vacuum technologies it can be used across the entire pressure range from atmospheric pressure to its ultimate vacuum. The evacuation of even larger systems from atmospheric pressure down to the 10-3 mbar vacuum range can be done without changing the vacuum pump.

VACUU·PURE easily handles high levels of vapor accumulation through its extraordinary condensate compatibility. Thanks to this capability, a gas ballast is unnecessary, avoiding associated disadvantages like the reduction in pumping speed and an increase in noise levels. The integrated regeneration mode enables rapid drying of the pump at the end of the process. This allows sample throughput to be increased significantly as compared to other pump technologies.

VACUU·PURE is also available in a chemically resistant design for working with aggressive gases and vapors.

Technical Highlights

100% oil-free

No hydrocarbons


For dry and hydrocarbon-free operation, VACUU·PURE takes the screw pump principle to the next level. The special design with two cantilevered spindles and a magnetic gear allows fully oil-free operation. This enables clean processes and pure products and protects the laboratory and environment. Save both time and operating costs, since there is no need to dispose of waste oil or to interrupt your work for oil changes.

VACUU·PURE does not generate hydrocarbons by abrasion

No abrasion

Clean processes, pure products


The working principle of VACUU·PURE is based on gap sealing. The unique operating principle enables contact-free rotation of the spindles.

The vacuum pump operates abrasion-free. This ensures an ultrapure vacuum as well as contamination-free exhaust air. In addition, there is no wear due to abrasion, allowing for continuous operation.

No wear parts

Safe processes without interruption


A major benefit of VACUU·PURE is that it does not have any wear parts. The spindles rotate contact-free. Components are manufactured with the highest precision, down to the smallest detail.

The special design enables you to run your process without interruption. VACUU∙PURE has no scheduled maintenance for replacement of wear parts. This saves time, reduces operating costs, and enables trouble-free operation.

Applications

VACUU·PURE 10 is suitable for the following applications: Fore-vacuum of turbomolecular pumps, analytics, drying, regeneration of cryopumps, heat treatment, coating and many more

Enthusiastic users

Customer Experiences with VACUU·PURE


A dry and hydrocarbon-free vacuum is indispensable for many applications such as in ultrahigh vacuum systems. As a dry fore vacuum pump for turbomolecular pumps, VACUU·PURE offers a deep ultimate vacuum that was previously unreachable with oil-free technologies. Additionally it provides high pumping speed for light gases in the pressure range down to 10-3 mbar.

"With VACUU·PURE, we finally get a hydrocarbon- and abrasion-free vacuum in a vacuum range of down to 10-3 mbar."

 

 

"We were particularly impressed by the fact that VACUU·PURE has good flow rates even at higher pressures. For this reason, we can use VACUU·PURE as early as the initial evacuation of our UHV systems (ultrahigh vacuum systems). We avoid switching between different pump technologies for pumping out our systems and use as a backing pump."

VACUU·PURE can operate continuously at higher pressures so that even larger systems can be evacuated from atmospheric pressure down to 10-3 mbar without the need for another pump technology. Without wear parts to change or troublesome oil changes to perform, VACUU∙PURE enables continuous operation without the need for regular maintenance.

In the case of drying processes, both the primary drying and subsequent residual drying can be performed with a single pump. In freeze drying, excellent results are achieved during the residual (aka secondary) drying phase due to VACUU·PURE's impressive ultimate vacuum.

VACUU·PURE easily handles high vapor loads through its extraordinarily high condensate compatibility. A gas ballast is therefore not necessary. The associated disadvantages such as a reduction in pumping speed and increased noise levels are thus avoided. The integrated regeneration mode enables rapid drying of the pump after the end of the process and thus the sample throughput can be significantly increased, as compared to other pump technologies.

"In all tests, VACUU·PURE demonstrated very good performance, even in the case of an unusually high vapor load. The regeneration mode of VACUU·PURE is very helpful to be able to start the next process very quickly. We believe that there is no comparable vacuum pump."
