Eaton Plate - 54 Series

Eaton Plate - 54 Series

This plate is a critical internal wear component for Eaton 54 Series hydrostatic pumps, which are widely used to power the drum drive on concrete transit mixers. Depending on the specific pump configuration, this refers to either a directional valve plate (available in clockwise/right-hand or counter-clockwise/left-hand rotations) or a bearing plate that regulates hydraulic fluid flow against the cylinder block. Replacing a worn plate during a pump rebuild is essential to restore volumetric efficiency, prevent internal fluid bypass, and ensure smooth, consistent mixer drum rotation.
