Used EDWARDS QDP80 #293766231 for sale

EDWARDS QDP80 is a roughing and backing pump designed for reliable operation in high vacuum applications. It is a dry-running mechanical pump used for removing gas molecules at medium vacuum pressures from the innermost chamber environment. EDWARDS QDP-80 is a modular design with a stainless steel or lubrication-free PTFE compression-gear driven pump, integrated steel rotor, and drive shaft. For dry pumping, the rotor is enclosed in isothermal housings which protect the rotor from environmental contaminants. The rotor rotates within a balanced aluminum housing that is vacuum rated and mechanically sealed. The rotor, impellers, and other precision machined components are carbon impregnated for improved wear characteristics and better lubrication of wear parts. QDP 80 features dry pump heads, motorized compensators, and a built-in controller interface. The pump heads are designed to capture and store gases more efficiently than conventional vacuum pumps. They are able to provide clean, dry, and oil free vacuum. The motorized compensators provide a reliable, adjustable back pressure regulation which further improves the pump's performance and helps maintain the condition of the pump components. Furthermore, integrated controller interface reduces the complexity of operation and provides full multiphase switching capabilities. QDP80 is equipped with an automatic water recirculation system to ensure a cool, quiet, and constant operational temperature. The pump has a programmable standby mode which allows operation at reduced speed and helps to protect the pump motor and bearings from thermal damage. QDP-80 provides reliable and efficient operation for vacuum applications that require speeds of up to 33 liters/second, withstand pressure up to 4 x 10-3 mbar, and support up to 3 x 10-4 mbar. This pump is available from EDWARDS in a wide range of configurations with different pumping speeds and pressures. Its modular design and standard accessories make EDWARDS QDP 80 as a reliable, cost-effective, and low maintenance pump.
