Abstract

Perfections in submersible centrifugal pumps, particularly suitable for pumping corrosive liquids at high temperatures, characterized in that they comprise A) a volute casing having an axial inlet opening and a tangential outlet duct, B) an impeller capable of rotating within said envelope and having a number of main working blades spaced around a central hub, and C) a drive shaft to which the impeller is fixed, there being no bearings between the casing and the impeller or drive shaft, a relatively large clearance being provided between the casing and the drive shaft, where the shaft enters in the wrapping, the impeller having a number of subsidiary vanes of less height than the main working vanes spaced around the central hub, these subsidiary vanes being located above the main vanes when the pump is immersed in the liquid to be pumped, so that the rotation of said subsidiary vanes with the impeller serves to decrease the flow of liquid through said clearance.
