Edwards ESDP12

The Edwards ESDP12 is a used scroll pump designed to deliver clean, oil free vacuum for laboratory and light industrial applications. As a dry pump, it avoids the oil contamination concerns associated with rotary vane technology, making it a good fit for analytical instruments, load lock systems, and general purpose vacuum work where sample or process purity matters. Its compact scroll design provides quiet, low vibration operation compared to older oil sealed pumps of similar capacity. This pump is built for continuous duty and requires minimal maintenance since there is no oil to change or dispose of, reducing operating costs over its service life. It is commonly used to back turbomolecular pumps, support mass spectrometers, or provide primary vacuum in analytical and research settings. The ESDP12 is valued for its dependable performance in mid sized vacuum systems where dry pumping is preferred over wet or oil sealed alternatives. Offered here in used condition, this Edwards ESDP12 is suitable for laboratories, research institutions, and vacuum equipment integrators seeking a reliable dry scroll pump at a fraction of new pricing. It is a practical option for those upgrading older oil sealed systems or adding backup capacity to an existing vacuum setup.
