Product Description
Eaton 70422 & 70423 Series Pressure-Flow Compensated Piston Pumps
Product Overview: The Eaton 70422/70423 series (formerly Cessna) is a range of axial piston variable displacement pumps specifically engineered for open-circuit mobile applications. Renowned for its precision PFC (Pressure-Flow Compensated) control, this series includes featured models like the 70422-RDU, 70422-RFH, and the 70122/70523 configurations (such as part no. 080211R121002). By integrating advanced load-sensing technology, these pumps automatically modulate output flow and pressure based on real-time demand, drastically improving operational precision and fuel efficiency. It is the premier choice for hydraulic systems in compact tractors, professional turf equipment, and municipal sweepers.
Key Technical Advantages:
Efficient PFC Compensation: Combines pressure and flow compensation (Load Sensing) to ensure actuators receive smooth and consistent speed response regardless of load variations.
Compact & Lightweight Architecture: Optimized housing design (available in high-strength aluminum or cast iron) provides a small footprint, ideal for installation in constrained engine compartments.
Whisper-Quiet Operation: The valve plate design is optimized for mobile machinery, effectively suppressing high-frequency pressure ripples and improving cabin noise levels.
High Dynamic Response: The variable mechanism reacts almost instantaneously to load changes, ensuring the responsiveness of steering and lift systems.
100% Industry Standard Compatibility: Strictly adheres to SAE mounting specifications, ensuring splined shafts (e.g., RDU/RFH specs) and flanges align perfectly for a seamless “drop-in” replacement.
