Abstract

L'invention concerne les pompes centrifuges, notamment en cuve. Elle consiste à former la tête de colonne de la pompe par une volute de refoulement fixée sur l'extrémité supérieure de la cuve et du tuyau de transmission. Elle est applicable aux pompes en cuve (du type dit à barrel) et aux pompes de forage.
