Used EDWARDS QDP80 / QMB250 #293659821 for sale

EDWARDS QDP80 / QMB250 is a reliable and efficient rotary vane pump designed for use in a variety of applications requiring high-vacuum pumping. The QDP80 is a single-stage pump, while the QMB250 is a two-stage pump with a maximum pumping speed of 25 cubic centimeters per second (cc/s). The QDP80 features a direct-drive motor, allowing for an efficient and energy-saving operation. The motor can be run on either single- or three-phase electrical supplies and operates at a maximum speed of 1400 rpm. The pump is designed with a single-piece cast-aluminum casing and contains a generously sized oil chamber and reserve. As a result, the pump is able to withstand large temperature fluctuations, ensuring reliable and efficient operation. The QMB250 features a stainless steel precision-balanced rotor surrounded by helical-shaped chambers. The chambers are partitioned using a unique lip seal system, creating a low-friction design and extending the life of the pump. The dual-stage design of the QMB250 allows the pump to achieve a higher vacuum than the single-stage version (up to 50 microns), making it ideal for applications requiring a very low vacuum. EDWARDS QDP80 QMB250 is designed for continuous operation and provides superior performance in all conditions. The robust design ensures a long service life with minimal maintenance and downtime, making it an ideal choice for applications requiring reliable and energy-efficient pumping. Its fast and efficient performance, combined with minimal noise and vibrations, make it an extremely well-suited for use in a wide variety of environments.
