Eaton Hydraulic Pump-Cw Apad Hprv

This is a genuine Eaton 5423 series heavy-duty hydrostatic pump, designed for the demanding hydraulic systems of concrete mixer trucks. As a variable displacement pump, it provides precise control over the hydraulic flow to power the mixer drum. This specific model features a clockwise (CW/Right Hand) rotation, an integrated charge pump with an 'A-Pad' mount for auxiliary components, and a high-pressure relief valve (HPRV) for system protection. It is a critical replacement part for maintaining the hydraulic drive system on various rear-discharge concrete mixers.
