Eaton Hydraulic Pump

Eaton Hydraulic Pump

This is a remanufactured Eaton 5423 series heavy-duty hydrostatic pump, a critical component for the hydraulic systems of concrete mixer trucks. It is engineered to provide reliable, variable flow to control the rotation of the mixer drum on equipment from major manufacturers like McNeilus, Terex, and Con-Tech. As a remanufactured part, it offers a cost-effective solution for replacing a failed or underperforming pump, having been rebuilt to meet original OEM specifications. Key features include its clockwise (CW) rotation and an integrated high-pressure relief valve (HPRV) for system protection.
