Used EDWARDS QMB1200 #91775 for sale

EDWARDS QMB1200 is a reliable and robust dry pump proven over years of service in a wide variety of industrial, research, and commercial applications. The pump is a multi-stage, rotary-vane type, oil-sealed vacuum pump that is engineered to deliver ultimate gas throughput at pressures over 1200 mbar (i.e., 1200 millibar) absolute when connected in series with other dry pumps. This makes EDWARDS QMB 1200 ideal for a range of tasks, such as rough vacuum pumping, deep vacuum production and exhaust pumping. QMB1200 comes with a two-phase motor and four-stage rotor structure. The first stage of the rotor incorporates a semi-hermetic design, which minimizes the direct contact between the rotor and the air or gas being pumped. This prevents the influx of dirt, which would otherwise lead to a rapid deterioration of performance. The second stage of the rotor features a revolving vane, again to minimize the amount of direct contact between the rotor and the substance being pumped. The third and fourth stages feature integral eccentrics, helping to enhance the efficiency and ultimate vacuum pressure generated by the pump. QMB 1200 is capable of withstanding a wide range of temperatures and altitudes, thanks to it's special engineering. The construction is made of special metals to enhance its durability and strength, enabling it to handle vacuum pressures of over 1200 mbar. Furthermore, the pump is certified safe to use and CE-compliant in accordance with applicable standards. EDWARDS QMB1200 is further equipped with a built-in pressure gauge, so operators can accurately measure the pressure within the pump during pumping operations. It also features built-in safety valves, visible oil-level indicator, manual shutoff, and inlet screen filter. All of these features work together to ensure the safe, efficient, and reliable operation of the pump. Overall, EDWARDS QMB 1200 is a cost-effective and reliable pump, capable of performing well under a variety of conditions. Its components are made of innovative and high-grade materials, which guarantee the maintenance-free operation and the long service life of the pump. With its low vibration and noise levels, QMB1200 serves as an ideal choice for users of all kinds, making it an indispensable part of any laboratory or industrial setting.
