Product Description
Eaton Vickers ADU Series (421 Series) Axial Piston Variable Pump
Product Overview: The Eaton Vickers ADU series (also internally designated as the 421 series) is a high-performance axial piston variable pump engineered for Open Circuit mobile applications. Renowned for its ultra-compact design and rugged cast-iron housing, this series is a staple in tractors, combine harvesters, material handling equipment, and compact construction machinery. Core models like the ADU080 and specific configurations such as 421AK00814B and 421AK00897B provide an exceptional power-to-weight ratio for modern hydraulic systems.
Key Technical Advantages:
Precise Flow & Pressure Control: The ADU series supports various compensator logics. Models like the 421AK00814B feature high-sensitivity pressure compensators that instantaneously modulate displacement based on load demand, boosting fuel efficiency and minimizing system heat.
Compact & Rugged Industrial Design: The 421 series utilizes an optimized swashplate structure that delivers a substantial 80cc displacement within a small installation footprint. Its robust construction allows it to easily withstand the shock loads and intense vibrations typical of mobile machinery.
Superior Low-Noise Performance: Acoustically optimized internal flow paths ensure exceptionally smooth operation. Even at a rated pressure of 210 Bar, the pump maintains low decibel levels, meeting modern standards for cabin quietness in agricultural and construction vehicles.
Global Interchangeability & Reliability: Adheres to worldwide mounting standards. Whether developing a new system or replacing a failed 421AK00897B unit, these pumps ensure 100% physical compatibility, reducing the complexity of field maintenance.
Specific Models & Technical Parameters:
Core Series: ADU Series, 421 Series, 421AK.
Detailed Config Codes: 421AK00814B, 421AK00897B, ADU080.
Displacement: 80 cm³/rev (80cc).
Pressure Ratings: Rated at 210 Bar (21 MPa); Peak cycles up to 280 Bar.
Applications: Agricultural machinery, material handling, and mobile hydraulic power systems.
