SDV suction pump can start at full speed from atmospheric pressure to a pressure of 1Torr (1.3mbar a), while the ultimate vacuum of up to 0.01Torr (0.013mbar a). KINNEY SDV series is a new generation of compact, energy-efficient screw pumps. The most important feature of the pump is variable pitch screw design than other competitors saving more than 30% of dry pumps, exhaust gas temperature is also lower. Dry screw vacuum chamber is completely dry without oil, through the air route design, SDV pump can handle condensable gas containing steam and gas containing small particles will not remain in the pump. Typical applications [1], the chemical and pharmaceutical processes 2, solvent recovery 3, forming 4, 5 dry etching, sputtering 6, vapor recovery Technical Parameters such as pitch SDV pumps are designed to improve the efficiency and reduce the exhaust gas temperature. SDV suction pump can start at full speed from atmospheric pressure to a pressure of 1Torr (1.3mbar a), while the ultimate vacuum of up to 0.01Torr (0.013mbar a).
