The present article is devoted to investigation of cryogenic pumping assembly developed at Russian Federal Nuclear Center (VNIIEF). The main scheme of facility is given, where KH-50M pump is a principle unit. The research concerns the pumping speed for the cryopanel cooled to ∼5K, dependent on gas load. The coolant consumption for the selected model of pump is determined.
