Eaton Vickers ADU & 421AK Series Hydraulic Piston Pumps for Mobile Applications

Product Overview: The Eaton Vickers ADU Series (including the 421AK mobile-specific configurations) stands as the high-efficiency power heart engineered specifically for mobile machinery and off-highway equipment. This series spans a comprehensive displacement range from the compact 41cc (ADU041) to the high-capacity 80cc (ADU080), featuring core models like the 421AK00955B. Purpose-built to handle the severe spatial constraints and frequent load fluctuations of mobile environments, these pumps deliver elite power density and superior fuel efficiency. They are the premier choice for zero-turn mowers (ZTR), compact construction equipment, telehandlers, and various municipal utility vehicles.

Key Technical Advantages:

• Optimized for Mobile Cycles: Specifically reinforced for the frequent start-stop duty cycles of mobile machinery, featuring excellent self-priming speeds and instantaneous pressure response.

• High-Reliability Compensator Logic: Offers versatile control options (e.g., Pressure Compensation, Load Sensing) to ensure flow-on-demand, effectively extending battery life or engine fuel range.

• Quiet-Running Technology: Incorporates patented valve plate dampening to drastically reduce hydraulic ripple noise, ideal for noise-sensitive municipal and landscaping operations.

• Rugged Heavy-Duty Architecture: Critical rotating components are hardened to withstand peak pressures up to 280 Bar, ensuring an extended service life under harsh outdoor conditions.

• Precision 421AK OEM Fit: As the preferred OEM solution for numerous mobile machines, the 421AK versions offer seamless “drop-in” replacement with original mounting specifications.
