Abstract: Centrifugal pumps are widely used for transporting suspensions, but their head performance is derated when non-Newtonian fluids and/or coarse solids are present. Some head deration methods are available for high viscosity Newtonian fluids, Bingham plastic fluids and for coarse solids in water. This paper presents a modification of the Hydraulic Institute head deration method that is suitable for any homogeneous non-Newtonian rheology. A modification of the Walker and Goulas method is also considered. Possible anomalous behaviour of kaolin slurries in centrifugal pumps is discussed. On utilise couramment des pompes centrifuges pour le transport de suspensions, mais le rendement de leur hauteur de charge est reduit en ´ presence de fluides non newtoniens et/ou de solides grossiers. Certaines m ´ ethodes de r ´ eduction de la hauteur de charge sont disponibles pour les ´ fluides newtoniens a viscosit ` e´ elev ´ ee, les fluides plastiques de Bingham et les solides grossiers que l’on retrouve dans l’eau. Cet article pr ´ esente une ´ modification de la methode de r ´ eduction de la hauteur de charge de l’Hydraulic Institute qui convient ´ a n’importe quelle rh ` eologie non newtonienne ´ homogene. Une modification de la m ` ethode de Walker et Goulas est ´ egalement envisag ´ ee. L’article traite ´ egalement du comportement anomal ´ possible des bouillies de kaolin dans les pompes centrifuges.
