HeptaDryTM
Dry Screw Pumps. Optimum Ultimate Pressure. Absolutely Oil-Free. Cool-Running.
With HeptaDry™, Pfeiffer Vacuum is once again providing the industry with another reliable, high-quality product. The pumps from this new series of dry screw pumps are optimally suited for their applications in connection with low and medium vacuum.
HeptaDry™ is a complete line of dry screw pumps. The line is designed for both industrial and coating applications. HeptaDry™ is the ideal solution for all areas in which oil-free vacuum is required. The pumping speeds that are offered by this series of products range from 100 to 600 m3/h. One special advantage consists of their specially coated, single-piece, variable-pitch rotors. They assure the efficient internal compression to reduce energy cost requirements in the HeptaDry™ pumps. This enables thermally sensitive gases to be pumped as well. Moreover, the direct gas flow in the pump prevents deposits. High-quality axial face seals between the bearing and suction chamber make for increased reliability.
