Abstract

A centrifugal pump has an open impeller conveying media containing solids with at least one blade that projects in the direction of an inflow. The surface of the open impeller is at least partially provided with a carbon layer, preferably a tetrahedral hydrogen-free amorphous carbon layer. A surface of an adjacent wear plate may also be coated with tetrahedral hydrogen-free amorphous carbon layer.
