Used VARIAN V 250 #9002263 for sale

VARIAN V 250 is a high-precision, oil-sealed rotary vane pump designed for applications requiring very low ultimate pressure. It utilizes a two stage pumping cycle to achieve the ultimate pressure of 1x10-4 Torr. The drive motor of the pump is normally supplied with 3-phase power providing a high quality, reliable operation. The pump's design features a series of annular vanes that are statically mounted within a rotor-stator design to compress incoming atmospheric gases and render them to the required pressure level. VARIAN V250's patented frictionless bearing design allows for variable speed operation, resulting in extremely low vibration and noise levels. Furthermore, the maintenance-free and lubrication-free brushless motor design ensures a long service life and extended operating time. V-250 offers several additional features to ensure maximum efficiency. The Anti-Siphon device provides protection against contamination of the equipment and the integrated gas ballast valve helps purge the system of non-condensable gas, increasing the unit's pumping speed. It also comes with an inlet line valve for controlling the incoming gas flow as well as a differential pressure gauge to monitor the machine's performance. V250 employs an extremely robust construction to ensure durability and reliability. It is designed to operate under a wide range of temperatures and an optional heat exchanger is available for those applications where low temperature is required. The optimized oil resevoir design greatly extends service intervals while an integrated pressure relief valve prevents tool overpressure. VARIAN V-250 is the ideal choice for applications requiring high performance and low ultimate pressure levels. Its patented design ensures precise pumping speed regulation, smooth operation and maximum uptime. The advanced features provide additional protection against contamination and guarantee an excellent service life. This high-quality oil-sealed rotary vane pump is a reliable choice for applications requiring reliable, low pressure performance.
