Abstract

L'invention concerne une pompe à griffes comportant deux arbres de rotor (14), qui portent chacun plusieurs rotors (10, 12). Les arbres de rotor (14), dans des modes de réalisation préférés, sont réalisés d'une seule pièce conjointement avec les rotors (10, 12) associés. Les arbres de rotor (14) sont disposés conjointement avec les rotors (10, 12) dans un carter de pompe (16, 18), plusieurs étages de pompe étant formés par le carter de pompe et les paires de rotors (10, 12) correspondantes. Afin de simplifier le montage, les arbres de rotor (14) sont d'une part réalisés d'une seule pièce avec les rotors (10, 12) et d'autre part, le carter de pompe est réalisé en deux parties. Dans un mode de réalisation préféré, un plan de séparation (24) du carter de pompe (16, 18) s'étend dans la direction longitudinale des arbres de rotor (14).
