Eaton Hydraulic Pump-Ccw

Eaton Hydraulic Pump-Ccw

This is an Eaton (now Danfoss) model 5423-648 variable displacement, closed-circuit hydrostatic pump. It is specifically designed for demanding mobile applications like concrete mixers, providing the necessary high pressure and flow to rotate the drum. This pump operates in a counter-clockwise (CCW) direction and comes equipped with a manual control valve and an integrated charge pump. It is a critical component for controlling the drum's speed and direction, making it an essential replacement part for maintaining the functionality of a mixer's hydraulic system.
