Abstract

Pompe centrifuge à double aspiration. Elle comprend un rotor dont font partie intégrante des déflecteurs situés sur ses côtés opposés. Le rotor est claveté sur un arbre dans une chambre du carter. Des bagues d'étanchéité sont fixées à l'intérieur de la chambre et des surfaces et des parois d'étanchéité orientées axialement sont disposées sur les déflecteurs et les bagues afin d'empêcher le liquide de fuir de l'orifice de refoulement du rotor et de refluer vers son orifice d'entrée. Des cales permettent de régler la distance axiale entre chacune des parois d'étanchéité des deux déflecteurs et le centre de la chambre qui contient le rotor. Application aux pompes centrifuges tournant à grande vitesse et refoulant un liquide à grand débit et à pression élevée.
