Product Description
LIC Hydraulic proudly presents the Eaton / Cessna 70422 & 70423 Series Axial Piston Pumps, a benchmark in medium-duty hydraulic propulsion. These variable displacement pumps, specifically the AAHRAF2809DAM00000AMA configuration, are engineered for high-cycle environments demanding precision flow control. Our units offer 100% original interchangeability, serving as a robust alternative to factory-fitted pumps on leading mobile machinery. Each assembly undergoes 100% dynamic load testing to ensure zero-leakage performance and full volumetric efficiency under peak operating pressures.

Key Technical Advantages
Bimetallic Valve Plate Technology: The valve plate is treated with a specialized bimetal sintering process, drastically reducing friction and preventing “seizing” under extreme pressure spikes.
Advanced Load Sensing Logic: The integrated compensator adjusts the swashplate angle instantaneously based on system demand, reducing heat generation and maximizing fuel efficiency for mobile equipment.
High Power Density: Compact design allows for high flow output within a small footprint, ideal for modern machines with limited engine compartment space.
Whisper-Quiet Operation: Precision-ground pistons and high-grade needle bearings minimize noise ripple, enhancing operator comfort during long shifts.
Application Areas
Skid Steer Loaders: Primary drive and implement pumps for brands such as Bobcat, New Holland, and Case.
Agricultural Equipment: Hydrostatic drives for harvesters, sprayers, and commercial mowers.
Specialized Utility Vehicles: Hydraulic power units for street sweepers and ground support equipment (GSE).
Expert Maintenance Tips
Case Drain Management: Always ensure the case drain line is piped directly to the reservoir with minimal backpressure. High case pressure is the #1 cause of shaft seal failure and slipper damage.
Pre-Fill Protocol: Never start the pump dry. Fill the pump housing with filtered hydraulic fluid through the highest drain port prior to the first startup to ensure immediate lubrication of the friction pairs.
Contamination Control: Maintain a cleanliness level of ISO 4406 18/13 or better. Given the high-speed nature of the 70423 series, even micro-particles can lead to rapid scarring of the cylinder barrel.
