Abstract
A pitot tube inlet for the pitot tube of a centrifugal pump is configured to improve pump efficiencies when processing fluids that have a solids content the type or character of which causes the solids to accumulate along the inner peripheral surface of the rotor of the pump. The pitot tube inlet is configured to contact and remove the accumulated solids from the rotor to lessen the drag on the rotor, to lessen degradation of the pitot tube and to improve pump efficiencies.
