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 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.
Can be used ideally either as stand-alone pumps or in combination with our OktaLine Roots pumps.
