Abstract

L'invention concerne une pompe destinée à transporter un fluide, comprenant au moins un dispositif de transport présentant au moins une chambre de transport (18), au moins un élément de chambre de transport indéformable (20) qui délimite au moins partiellement la chambre de transport (18), et au moins un élément de transport déformable élastiquement (22) qui, conjointement avec l'élément de chambre de transport (22), délimite la chambre de transport (18) et est disposé sur l'élément de chambre de transport (22) ; au moins une unité d'entraînement (16) destinée à agir sur le dispositif de transport ; et au moins un carter (14) destiné à recevoir le dispositif de transport, le carter (14) étant formé au moins séparément de l'élément de chambre de transport (20) du dispositif de transport, en particulier du dispositif de transport dans son ensemble, en particulier de sorte que l'élément de chambre de transport (20), en particulier le dispositif de transport, puisse être retiré du carter (14) dans son ensemble. Selon l'invention, l'élément de chambre de transport (20) comporte une face extérieure qui est reliée à une face intérieure du carter (14) par ajustement à force et/ou de forme, lorsque le dispositif de transport est agencé sur le carter (14), en particulier la face extérieure repose contre la face intérieure du carter (14) lorsque le dispositif de transport est agencé sur le carter (14), et l'élément de chambre de transport (20) entoure au moins en grande partie l'élément de transport (22) le long d'une direction circonférentielle s'étendant sur un plan s'étendant au moins sensiblement perpendiculairement à l'axe d'entraînement (70) de l'unité d'entraînement (16).
