Used ALCATEL / ADIXEN / PFEIFFER ADP 81 #9011905 for sale

ALCATEL / ADIXEN / PFEIFFER ADP 81 is an evolutionary step towards oil-free, dual-stage diffusive vacuum technology. Developed by ADIXEN Vacuum, this enhanced double-stage molecular drag (eDP) turbo-molecular pump is an efficient alternative for applications that have traditionally relied on oil-based pumps. ADIXEN ADP 81 leverages a unique base pressure profile, valve-less design, and low-radiation bearing set to reduce operating costs while maximizing reliability and process performance. With a maximum pumping speed of 80 liters/second, its higher volumetric production rate allows for faster equipment conditioning. ALCATEL ADP 81 also operates at power levels as low as 170 watts for a higher efficiency and longer service life. Turbo-molecular pumps typically employ an annular stator that runs in tandem with a turntable-mounted rotor to directly move the gas molecules from the low-pressure side of the pump to the high-pressure side, while the double-stage eDP turbo-molecular pump utilizes two stages of stators and one single rotor. This maximizes compression efficiency and cuts down on vibrational noise and heat, allowing PFEIFFER ADP 81 to handle a wide range of operating requirements. In addition, ADP 81's valve-less, oil-free design means the system requires minimal maintenance. Compared to oil-sealed pumps, ALCATEL PFEIFFER vacuum unit does not require regular oil changes or flushing of lines. Furthermore, its advanced machine utilizes FVa-flux valves to prevent gas recirculation and reduce air contamination, eliminating the need for costly bypass valves. ALCATEL / ADIXEN / PFEIFFER ADP 81 is designed for environments that require high-speed operation in a clean, contamination-free working zone. Its robust design ensures low maintenance and maximum uptime. Whether for vacuum application in semiconductor manufacturing, research laboratories, or general industry, the innovative ADIXEN ADP 81 double-stage eDP turbo-molecular pump offers superior performance and total reliability.
