Eaton Series Mixer Pump | 4623, 5423, 6423, 7620 | Hydraulic Pump for Concrete Transit Mixer

Heavy-Duty Axial Piston Variable Pump for Concrete Transit Mixers

Product Overview: This series of heavy-duty axial piston variable displacement pumps is the quintessential core of transit mixer drive systems worldwide. Specifically engineered for closed-circuit applications, the range covers industry-standard models including 4623, 5423, and larger displacements like 6423 and 7620. Renowned for their extreme durability and stability in harsh construction environments, these pumps provide precise bi-directional control and robust torque output, ensuring concrete remains perfectly mixed and fluid throughout the haul.

Key Technical Advantages:

• Engineered for Mixer Duty Cycles: Built to withstand frequent starts, stops, and rapid reversals typical of jobsite operations, ensuring 24/7 reliability under heavy shock loads.

• Integrated Closed-Loop Design: Features a built-in charge pump, high-pressure relief valves, and control valve manifolds, simplifying vehicle plumbing and maximizing overall system efficiency.

• Precision Displacement Modulation: Supports manual hydraulic or electric proportional control for stepless drum speed adjustment, catering to everything from high-speed loading to controlled discharge.

• Superior Cooling & Efficiency: Optimized fluid passages and high-precision rotating groups significantly reduce heat generation, extending the service life of hydraulic oil and seals.

• 100% Industry Standard Compatibility: Manufactured to strict international specifications for major mixer brands (e.g., Sany, Zoomlion, Liebherr), ensuring a seamless “drop-in” replacement for original units.
