Abstract

Groupe de pompage L’invention concerne un groupe de pompage comportant : une pompe à vide primaire, une pompe à vide de type Roots (3) comprenant un étage de pompage (7) ayant un stator (9) à l’intérieur duquel deux rotors (5) Roots sont configurés pour tourner de façon synchronisée en sens inverse pour entrainer un gaz à pomper entre un orifice d’entrée (10) et un orifice de sortie (11), une canalisation (13) reliant l’orifice de sortie (11) à une aspiration (12) de la pompe à vide primaire (2), caractérisé en ce que la plus petite distance (d) entre une bordure de l’orifice de sortie (11) et chacun des rotors (5) dans l’étage de pompage (7) est au moins inférieure à trois centimètres.
