High vacuum pumping stations

Turbomolecular pumping stations provide a convenient means for evacuating laboratory cryostats and transfer lines to high vacuum levels (<10-6 Torr). Turbopump stations include a turbopump controller, roughing/backing pump, vacuum gauging, as well as a 5 ft long flexible pumping line, and valves. The turbopump module utilizes low maintenance ceramic bearings while the mechanical pump includes vibration absorbing mounting. The entire pumping system is mounted on casters for easy movement throughout the laboratory. Two standard configurations are described below. Custom configurations can include larger pump capacities, different gauging, and various inlet flanges.
