A rotary positive-displacement pump comprises two gear wheels which mesh with each other without encapsulation. Each gear wheel has a plurality of teeth with a profile which falls within a band of tolerance of ~ 1/20th of the depth of the tooth with respect to a theoretical profile similar to a profile defined by a natural spline function passing through a plurality of nodal points having pre-established coordinates {X, Y}.
Pompe rotative volumétrique munie de deux engrenages en prise sans capot. Chaque engrenage comprend plusieurs dents dont le profil se situe dans une bande de tolérance correspondant à ± 1/20e de la profondeur de la dent par rapport à un profil théorique semblable à un profil défini par une fonction spline passant par de multiples points nodaux ayant des coordonnées préétablies {X, Y}.
