Product Description

Rexroth A4VG140 High-Pressure Hydraulic Pump for Heavy-Duty Machinery

Product Overview: The Rexroth A4VG140 Series is the global heart of hydrostatic transmission systems for heavy-duty mobile machinery. This featured model, A4VG140EP4D1/32R-NAF02F021DP-S, is a variable displacement axial piston pump specifically optimized for closed-circuit operations. Integrating the charge pump, high-pressure relief valves, and control valves, it provides superior power density. Utilizing advanced EP (Electric Proportional Control) technology, it delivers precise flow adjustment and rock-solid stability for heavy excavators, road machinery, and cranes, ensuring powerful traction under grueling conditions.

Key Technical Advantages:

  • Optimized for Heavy Loading: Specifically reinforced for the frequent load fluctuations typical of construction environments, offering exceptional impact resistance and extended service life.

  • Precision EP Proportional Control: Equipped with the EP4 Control Module, allowing for millisecond-level stepless adjustment of displacement for smooth acceleration and precise reversals.

  • Fully Integrated Closed-Loop Design: Highly integrated architecture minimizes external plumbing connections, reducing leakage risks and simplifying installation in crowded engine compartments.

  • Elite Power Density: The 140cc displacement combined with a swashplate design maintains high-efficiency power output even at continuous pressures of 400 Bar.

  • Global OEM Compatibility: Fully compliant with original mounting parameters for leading brands like Caterpillar, SANY, and XCMG, supporting seamless “Plug-and-Play” replacement.

Detailed Models & Parameters:

  • Core Series: Rexroth A4VG Series 32 (High Pressure).

  • Full Model Code: A4VG140EP4D1/32R-NAF02F021DP-S.

  • Displacement: 140 cm³/rev.

  • Control Type: EP (Electric Proportional Control).

  • Pressure Ratings: Rated at 400 Bar (5800 PSI) continuous; Peak capability up to 450 Bar.

  • Rotation: R (Clockwise/CW).

  • Target Applications: Heavy excavator travel drives, roller hydrostatic systems, and concrete pump trucks.
