Abstract

L’invention concerne une pompe à cavités progressives propre à déplacer un fluide, la pompe comprenant :- un premier stator (10) comportant une première armature (24) et un premier tube hélicoïdal (26) fixé à l’intérieur de la premier armature, le premier tube hélicoïdal ayant un premier pas (P1) ; - un deuxième stator (12) comportant une deuxième armature (28) et un deuxième tube hélicoïdal (30) fixé à l’intérieur de la deuxième armature, le deuxième tube hélicoïdal ayant un deuxième pas  (P2);- un rotor hélicoïdal (18) monté rotatif dans le premier tube hélicoïdal et dans le deuxième tube hélicoïdal, le rotor hélicoïdal étant entrainé en rotation pour déplacer le fluide du premier stator vers le deuxième stator, le deuxième pas présentant une longueur supérieure à la longueur du premier pas, la longueur du deuxième pas étant au moins supérieure à 0,15 % de la longueur du premier pas.
