Chemically resistant and oil-free vacuum down to 10-3 mbar
5 Nov 2020
VACUUBRAND introduces a chemically resistant, oil-free screw pump for vacuum down to 10-3 mbar with its VACUU·PURE 10C.
The pump features maintenance-free technology with no wear parts and delivers a pumping speed of 9 m3/h. Users benefit from clean processes, greater efficiency and improved sustainability.
VACUU·PURE 10C is suitable for processes in which aggressive gases or vapours are pumped and clean vacuum is also required – such as analytics, chemistry, life sciences and pharmaceuticals. The pump can be used for processes such as vacuum drying, Schlenk lines, heat treatment, distillation, degassing, coating, or as fore vacuum for turbomolecular pumps.
The instrument, which can also be used continuously at higher pressures, features two cantilevered spindles and a magnetic gear which is completely oil-free. The spindles run contact-free, eliminating wear and abrasion and enabling clean processes and pure products without contamination by oil or lubricants. This helps protect the laboratory and the environment, as oil emissions and waste oil disposal are eliminated. The contact-free, lubricant-free design means that no regular maintenance is required. The vacuum – and the purity of the process – are not affected by wear and tear of wear parts.
To work with aggressive gases or vapours, wetted components of the VACUU-PURE are made of chemically resistant plastics. A thick PEEK encapsulation protects the spindles and stator in the pump chamber. The high chemical compatibility allows efficient pumping without interruption – an upstream cold trap is not necessary in most processes. The optimised screw pump also features high condensate tolerance, which means that no gas ballast is required, even with high chemical vapour generation. An integrated regeneration mode allows the vacuum pump to dry quickly after the end of the process.
Dr. Barbara Richarz, Head of Product Management at VACUUBRAND, said: "With the innovative new VACUU·PURE pumps, we have succeeded in extending oil-free and chemically resistant vacuum technology to the vacuum range down to 10-3 mbar. Our customers benefit from this technical advancement, as it enables them to achieve clean processes, efficient work, reliable performance, and sustainability in everyday laboratory life."
For working with non-corrosive media there is the VACUU-PURE 10 without chemical compatibility. It is designed for high-purity processes where dry- and hydrocarbon- free vacuum is a must. VACUU·PURE 10 also provides dry vacuum down to 10-3 mbar.
