Varian DS-102

Offered here is a used Varian DS-102 vacuum pump, part of the Varian direct drive rotary vane pump series widely used as a roughing and backing pump in laboratory and industrial vacuum systems. This compact model provided dependable rough vacuum generation for smaller instrument setups and served as the backing pump for higher vacuum stages such as diffusion or turbomolecular pumps. The DS-102 was commonly found supporting mass spectrometers, leak detection equipment, and general vacuum chamber applications where a compact and reliable rotary vane pump was needed. Its direct drive design reduced maintenance requirements compared to belt driven alternatives, which made it a favored option in labs seeking straightforward, low upkeep vacuum solutions. This particular pump is used and sold as is, making it suitable for buyers supporting existing Varian vacuum trains, looking for a working replacement unit, or stocking a spare for ongoing instrument maintenance. It provides a practical path to keeping older vacuum dependent systems running.
