ABSTRACT:
A vane-type impeller having a plurality of abuttably-adjacent, interconnected components at least some of which are made of an abrasion-resistant ceramic material is improved by a layer of a resiliently-flexible material between at least each component made of an abrasion-resistant ceramic material and each component it is abuttably adjacent for increasing the capability of each component made of the abrasion-resistant material of withstanding impact forces.
