Used EDWARDS QDP40 #110271 for sale

EDWARDS QDP40 is a sliding vane pump ideal for use in vacuum systems. It is a positive displacement pump that is rotary and uses vanes driven by an eccentric rotor. It is extremely efficient and can offer a nearly constant pumping speed over a wide range of pressures. EDWARDS QDP 40 can rotate at speeds up to 12,500 rpm and has a maximum inlet capacity of 2,500 liters per hour. It is made of stainless steel which makes it durable and it is also highly resistant to corrosion. The pumping action of QDP40 is optimized by two components: the vanes and the fixed retaining stages. It features stainless steel rotor vanes with three angled faces, which are made to exact specifications for performance and maximum efficiency. This allows for controlled admission and exhaust of air and allows the vanes to slide easily with little friction, resulting in smooth performance even at high speeds. In addition, its simple and robust design ensures a good level of reliability. QDP 40 also provides a higher compression ratio than other pumps and can maintain a consistent pumping speed even at low pressures. It is also highly efficient, with a typical volumetric efficiency of 95 percent or greater; and it is capable of handling liquids, gases and vapors. EDWARDS QDP40 is an ideal solution for many applications in the industrial, aerospace, automotive and medical industries. It is also utilized in turbo compressors and vacuum pumps, where its air-handling capabilities and reliability makes it an excellent choice. It can operate in temperatures between -5ºC and 65ºC and is easy to maintain due to its robustness. This makes it an ideal option for applications where the vacuum conditions must be maintained accurately.
