Varian DS-302

This listing covers a used Varian DS-302 rotary vane vacuum pump, a step up in capacity from smaller models in the Varian direct drive pump series. It was built to provide reliable rough vacuum generation for a range of laboratory and industrial applications, including serving as a backing pump for high vacuum stages in analytical instrumentation. The DS-302 found use in settings such as vacuum chamber evacuation, mass spectrometry support, and general purpose laboratory vacuum systems where a slightly higher pumping speed was needed compared to entry level models. Its rotary vane mechanism and direct drive configuration offered dependable operation with manageable maintenance demands over years of service. This used unit is sold as is and is well suited to technicians and labs maintaining existing Varian vacuum systems or seeking a functional spare or replacement pump. It offers continuity for legacy equipment that still depends on this specific pump model to operate.
