Used EDWARDS QDP80 #9246244 for sale

EDWARDS QDP80 is a two stage, rotary vane vacuum pump designed to provide reliable, efficient, and powerful performance for a variety of industrial and scientific applications. EDWARDS QDP-80 is capable of reaching a maximum pressure of 740 mbar (0.3 Torr) over an ultimate pressure of 1.2 mbar (2 x 10-4 Torr) with a displacement of 13 m3/h (90 cfm). It is a single-phase operating dry pump, which ensures a low maintenance and high durability operation. QDP 80 contains two pumping stages, the first one is an oil-sealed vacuum pump which compresses the atmospheric pressure of the process chamber down to a low pressure. This is then followed by the second stage, a Dry Rotary Vane Pump (DRV) which further reduces the pressure. The DRV is designed to deliver high pumping speed in the range of 1-750 mbar, with dual impeller configuration for added performance and reduced vibration. The DRV also features a low noise operation, which makes it suitable for application where noise is an issue. QDP80 is also equipped with a mechanical seal which is located between the pumps to ensure a superior vacuum in the process chamber. The seal helps to reduce oil leakage and increase the performance of the pump by preventing the oil from back streaming into the process chamber. QDP-80 also features a suction port, which allows for an external vacuum source to be connected. This eliminates the need for constant maintenance and helps to increase the overall performance of the pump. To ensure a long life of operation, EDWARDS QDP 80 is equipped with an automatic oil level control equipment. This system maintains a constant oil level for optimal operation and prevents the pump from damage due to oil low levels. The automatic pressure control unit automatically adjusts the operation of the pump to accommodate changes in the process chamber's pressure. EDWARDS QDP80 is also designed with safety features to help protect the pump against over-heating and excessive pressure. EDWARDS QDP-80 is a reliable and efficient pump that is capable of providing excellent performance for a variety of industrial and scientific applications. With its large displacement, dual stage machine, and integrated safety features, QDP 80 is sure to deliver the necessary performance in a variety of different working scenarios.
