Used PFEIFFER / BALZERS DUO 2.5 #9242427 for sale

BALZERS DUO 2.5 is a high-end dual-stage, dry-running, rotary vane pump designed for vacuum technology applications. It is composed of two vane stages and is equipped with a built-in oil reservoir, ensuring uninterrupted operation. The DUO 2.5 offers a number of advantages over conventional vacuum pumps, such as a high pumping speed, versatile pumping range, and low noise emission. The DUO 2.5 is a safe and reliable vacuum pump ideal for demanding applications for which combination of low absolute pressure and a wide pumping range are required. By making use of two pumping stages in series, it has a wide pumping range of up to 0.012 mb (mbar) and a maximal pressure of 0.133 mb (mbar). This allows for its use in both low and very high vacuum applications. The DUO 2.5 operates by using a rotor and two eccentric driven vanes to create a crescent-shaped pumping chamber. The rotor is driven by a mechanical seal as well as by two permanent magnets, located on the inner walls of the two end plates. When the rotor turns, the pumping chamber is swept of air, and the air is pushed out through the outlet and into the exhaust line. The DUO 2.5 has a high pumping speed, with a maximum flow rate of 44m³/hour and a frequency of 6500rpm, making it an effective dust and vapour pumping device. Its noise emission preparation and exhaust system keep noise levels to an acceptable level, with noise levels at 65dB(A) at 1 meter distance. Its versatile nature allows it to be used for various applications such as leakage tests, vacuum packaging, food processing, hot end coatings, and degassing. The DUO 2.5 is equipped with a built-in grease reservoir, allowing for easy and efficient re-greasing of the bearings and seals. The Duo 2.5 also includes a built-in check valve, allowing for greater operational safety and reduced power consumption. Overall, PFEIFFER DUO 2.5 is an advanced, versatile, and reliable vacuum pump ideal for a range of applications where combination of low pressure and wide range pumping are required. It features a high pumping speed, reduced noise emission levels, and a built-in check valve, making it a great choice for demanding and time-sensitive applications.
