An innovation in vacuum technology. Clean and oil-free 10^-3 mbar vacuum.

Vacuubrand team of experts developed VACUU·PURE® for contamination-free vacuum that lets your clean processes run efficiently. Vacuubrand dry screw pumps meet challenges where other technologies fall short.

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 oil and abrasion free. This ensures an ultrapure vacuum as well as contamination-free exhaust air. In addition, there is no wear due to abrasion and no need for oil changes, allowing for continuous operation.

The chemically resistant version VACUU·PURE® 10C, features wetted materials made of chemically resistant polymers. A thick-walled PEEK encapsulation protects the spindles and stator in the pumping chamber, providing high chemical resistance. The use of a cold trap is unnecessary in many cases – another plus for reliable, continuous and economical operation.

Applications:

• Fore vacuum generation for turbomolecular pumps.
• Analytical applications.
• Regeneration of cryo pumps.
• Vacuum drying.
• Freeze drying.
• Heat treatment.
• Degassing.
• Coating.
• Distillation.
• Schenk line.

Some customer experiences with VACUU·PURE®.

"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."

"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."
