Used EDWARDS QMB500 #293813883 for sale

EDWARDS QMB500 pump is a turbomolecular vacuum device designed to provide ultimate low-vacuum pressures. The pump comes equipped with a complete unit of monitoring devices, including a pressure gauge and a gas ballast valve. The device is comprised of a 6-stage axial-flow turbine compression equipment and a backing pump, allowing for the highest compression ratios at ultimate low-vacuum pressures. To maximize performance, EDWARDS QMB 500 has a pumping speed of 1000 l/s, a base pressure down to 5 x 10-5 mbar, and an ultimate pressure of 7 x 10-7 mbar. With this level of performance, the device can easily handle all the necessary vacuum requirements of most general-purpose laboratory applications. QMB500 is designed for quiet operation, with vibration levels below 65 dB(A). Additionally, the device features an integrated permanent magnet motor, which enables precise motor drives and optimized start-up characteristics. The pump is also equipped with several advanced features, such as Groove-on-Tube technology, which increases oil vapor entrainment and significantly reduces friction loss in the bearings. QMB 500 is designed for safety and efficiency, with several key features, such as an auto-start system, thermal-pressure-relief unit, and contamination-proof filter. Additionally, the device comes with a set of self-monitoring devices, including a rigidly mounted, dual-window optical pressure chamber with integrated inlet adapter. This feature enables fast and accurate sampling of the pump's ultimate pressure and eliminates the need for manual operation. EDWARDS QMB500 is engineered for ease of use with an easy-to-read, illuminated control panel that allows users to adjust pump speed and other settings. Additionally, the device comes with an intuitive start-up mode to quickly complete the initialization process. Overall, EDWARDS QMB 500 is a reliable and easy-to-use turbomolecular pump that can provide comprehensive vacuum solutions for a variety of general-purpose laboratory applications. With its 6-stage axial-flow turbine compression machine, advanced features, and easy-to-read control panel, QMB500 is sure to deliver reliable and efficient results.
