Sargent Welch Turbo Torr Turbomolecular Vacuum Pump Lot #Two Pumps & Controller. X-NASA owned equipment, University of Iowa. That’s all the history I could get. University tech said they had been in the Laser Optics/Physics Lab for years and couldn’t tell me more. Everything appears to be in good condition. Impellers spin nice and smooth, controller appears to be in good condition with no obvious burnt up parts, etc but I couldn’t get pumps to run. Hopefully an easy fix and you will end up with two pumps and a controller. Contact me for quote. Need address, zip & location description residential? With dock or forklift?
