Eaton Hydraulic Pump

Eaton Hydraulic Pump

This is an Eaton 5423-550 heavy-duty, variable displacement piston pump, specifically configured for the hydraulic systems of concrete transit mixers. It features a clockwise (Right Hand) rotation, manual displacement control, and an integrated A-Pad for mounting a charge pump. Built with a robust cast iron housing, it is designed to provide the high pressure and variable flow required to consistently rotate the mixer drum. This pump is a critical replacement part for maintaining the hydraulic drive system on McNeilus, Con-Tech, and other rear-discharge concrete mixers.
