Used EDWARDS QMB250 #9137968 for sale

EDWARDS QMB250 is a high-performance, compact molecular drag pump designed for a variety of vacuum applications. It is capable of pumping down to a base pressure of 1.5 x 10-4 mbar. The design of EDWARDS QMB 250 uses a unique motor-driven, axial piston-driven turbo-molecular pump which provides a smooth, high-efficiency operation. QMB250 is constructed from stainless steel and is highly corrosion resistant. The turbo-molecular pump is driven by a bearingless, external, brushless permanent-magnet synchronous motor that provides an effective speed range from 500 to 1,400 rpm. This allows it to handle a wide variety of vacuum system applications. QMB 250 has a power supply of 220 Volt AC (50/60 Hz). EDWARDS QMB250 is suitable for a broad range of applications including research and development, industrial process control, and medical vacuum processes. It is capable of handling a wide variety of gas types including air, nitrogen, argon, HELIUM, CARBON DIOXIDE, and OXYGEN. It can also effectively pump out water vapor and other condensable gases. EDWARDS QMB 250 has a high level of versatility due to its wide range of operating pressures, temperatures, and applications. The pump's inner workings have been designed to reduce noise and vibration for a quieter, more efficient performance. Its low power consumption of 48 Watts also helps to reduce energy usage. In addition, QMB250 features a built-in catch valve that reduces the risk of back-streaming. This helps to maintain the ultimate vacuum by blocking the return of process gases that can degrade quality and performance. Moreover, it has a replaceable filter to ensure a clean, high-quality vacuum atmosphere. Overall, QMB 250 is an ideal choice for any application requiring a reliable and high-performance pump. It offers versatile, efficient, and high-quality performance, and its built-in safety features ensure a safe, reliable operation.
