Used EDWARDS QDP80 #9267185 for sale

EDWARDS QDP80 is a high performance, dual stage vacuum pump designed and manufactured by EDWARDS. It is an ideal choice for many industrial processes that require long pump life and excellent vacuum performance, such as freeze drying, coating, distillation, and vacuum packaging. EDWARDS QDP-80 pump is equipped with a 6.6 horsepower motor and a two-stage oil lubricated rotary vane configuration, facilitating maximum pumping speeds from 0.2 m3/hour at 78 m Torr to 12.9 m3/hour at 50 m Torr. Furthermore, it is equipped with a unique oil inlet chamber design which reduces turbulence within the chamber while still holding a tight oil seal within the chamber. This helps to reduce oil mist and noise levels while maximizing pump efficiency. Additionally, the two-phase pump operation improves temperature control by modulating the motor speed between high and low pressure levels. QDP 80 also contains a high grade Aluminum alloy bearing box, providing good corrosion resistance. Its balanced and dynamically improved rotor design supports reduced vibration and longer life times. For safety and protection, the motor is equipped with built-in surge protection and a high compression polychloroprene neoprene diaphragm for the mechanical seal of the oil pump. In addition, QDP-80 delivers excellent performance regarding both ultimate vacuum levels and pumping speed. By utilizing EDWARDS integral spare parts and accessories, the pump can be used to achieve an ultimate vacuum of less than 1xE-4 mBar, and the maximum attainable pumping speed can exceed 80 m3/hour. QDP80 vacuum pump is reliable, efficient, and is designed to provide safe, long-term performances limits. Its superior performance is ideal for many industrial and laboratory processes, such as freeze drying, vacuum coating, distillation, and vacuum packaging.
