EDWARDS QDP80 / QMB250 is a high-performance rotary vane pump specifically designed for applications that require high vacuum levels but do not require large volumes of air. The pump is suitable for medium to high vacuum applications such as those involved in chemical vapor deposition, distillation, freeze drying, rotary evaporation, sublimation, and many other industrial and scientific processes. The pump consists of a single stage, four-blade rotor and two carbon-graphite vane pumps which are driven by a high-torque motor. The rotor is dynamically balanced and runs in an oiled cast iron body that has been potted for vibration dampening. The pump is rated for pressures up to 100 mbar inlet and 250 mbar exhaust. The pumping speed is 800 litres per minute (l/min) and the maximum allowable vacuum is 7.5 x 10-3 mbar.
