Abstract

L’invention concerne une pompe à cavités progressives (2) pour le pompage d’un liquide agro-alimentaire, la pompe à cavités progressives comportant un stator, un rotor hélicoïdal et un dispositif d’entrainement (8) comportant :- un carter (18) délimitant une chambre d’aspiration, - un arbre d’entrainement (27, 30) entrainé en rotation, - une armature (46) entrainée en rotation par l’arbre d’entrainement, - un mécanisme de transmission (28) fixé au rotor et à l’arbre d’entrainement,- une gaine primaire (82) enveloppant le mécanisme de transmission,- une gaine secondaire ( 86) fixée d’une part, au rotor et au mécanisme de transmission, et d’autre part, à l’armature(46); la gaine primaire, la gaine secondaire et l’armature délimitant une chambre de récupération propre à récupérer du liquide pompé lorsque l’étanchéité entre la gaine secondaire et le rotor est imparfaite.
