A pump and, in reverse operation, a motor, for pumping viscous fluids is disclosed, comprising a rotor and stator each having opposite handed threads, and a fluid path between them, one of the stator motor having a solid body, typically in the sense that it has no throughbore.
L'invention concerne une pompe, en action inverse, permettant de pomper des fluides visqueux, qui comprend un rotor et un stator équipés chacun de filets à symétrie opposée, entre lesquels passe un trajet de fluide. L'un ou l'autre du stator et du rotor est doté d'un corps solide, ce qui s'entend généralement d'un corps dans lequel aucun trou de passage n'est pratiqué.
