A cryogenic pump with an essentially cup-shaped housing (2), with a radiation screen (4) disposed in the housing and also essentially cup-shaped, with an inlet opening (6), with a cold head (3) extending into the housing and the radiation screen, with pump surfaces (15) for condensable gases, disposed on the cold head, with a collecting chamber for liquid condensate developing during regeneration of the pump; in order to make possible a regeneration of the pump in various installation positions it is proposed that the condensate collecting chamber is laterally disposed in such a way that the pump (1) can be regenerated even if attached horizontally.
