Product Description
John Deere AT Series High-Efficiency Hydraulic Piston & Vane Pump
Product Overview: The John Deere AT series hydraulic pump line is a premium power solution engineered specifically for heavy-duty construction machinery. Covering critical part numbers AT172603, AT180926, and AT227997, this series integrates advanced axial piston technology with high-efficiency vane or gear charge mechanisms. Designed to meet demanding flow requirements, these pumps serve as the “heart” of the hydraulic system, driving travel, steering, and implement functions. They ensure superior maneuverability and fuel economy even during heavy excavation or high-speed operation.
Key Technical Advantages:
Multi-Functional Integrated Power: Combines the high-pressure capabilities of piston pumps with the stable flow of vane/gear pumps to satisfy both main and pilot pressure demands.
Superior Volumetric Efficiency: Precision-ground rotating groups and low-friction designs minimize internal leakage, ensuring stable output under high pressures exceeding 280 Bar.
Heavy-Duty Wear-Resistant Architecture: Featuring reinforced bearing systems and specialized seals, these pumps are hardened to withstand extreme job site conditions, including high dust and intense vibration.
100% Drop-in Compatibility: Manufactured to strict John Deere factory mounting standards—including spline shafts, flanges, and porting—ensuring a seamless “plug-and-play” installation.
Excellent Load-Sensing Response: Integrated pressure compensation and flow regulation allow the pump to adjust output instantly based on workload, preventing engine stalling.
Detailed Models & Parameters:
Core Part Numbers: AT172603, AT180926, AT227997.
Compatible Equipment: John Deere Graders, Wheel Loaders, and Excavators.
Pump Types: Axial Piston, Vane, and Gear combinations.
Pressure Ratings: Supports operating pressures up to 280-350 Bar (depending on specific model application).
Primary Applications: Main Hydraulic Power, Steering Assist, and Cooling Cycle Systems.
