Eaton Hydraulic Pump

Eaton Hydraulic Pump

This Eaton 5423 series hydraulic pump is a heavy-duty, variable displacement unit specifically used in the closed-circuit hydrostatic transmission systems of concrete mixer trucks. It provides the necessary high pressure and high flow rate to power the hydraulic motor that turns the mixer drum, ensuring consistent rotation speed whether the truck is in transit or stationary. This pump is a critical replacement part for maintaining the hydraulic system's performance and reliability on equipment from manufacturers like McNeilus, Terex, and Con-Tech. Its robust cast-iron construction ensures durability and noise dampening in demanding, heavy-load applications.

Key Features

• Variable displacement axial piston design for precise control of drum speed.
• Counter-clockwise (CCW) input shaft rotation.
• High-strength cast iron housing for durability and noise reduction.
• Features an integrated gerotor charge pump to supply the closed-loop system.
• Designed for high-pressure, heavy-load applications typical of concrete mixer drum drives.
• Equipped with an 'A-Pad' auxiliary mounting flange.
