Product Description

Rexroth A4VG71 Series High-Pressure Closed Circuit Variable Pump

Product Overview: The Rexroth A4VG71 series is a high-performance axial piston variable displacement pump designed for hydrostatic transmissions in closed-circuit mobile applications. Featured models like the A4VG71DA1D7/32R-NZF02F041SH (associated with factory code D-89275) integrate advanced DA Speed Related Control. This series automatically modulates output flow based on engine speed, providing smooth and powerful traction for mobile machinery. It is the industry standard for wheel loaders, excavator traction drives, agricultural machinery, and municipal specialty vehicles.

Key Technical Advantages:

  • DA Speed Related Control: Displacement adjusts automatically relative to engine RPM, offering an “automatic transmission” feel that optimizes fuel efficiency and simplifies operator control.

  • Highly Integrated Architecture: Features a built-in charge pump, high-pressure relief valves, and control valve groups, significantly reducing external hydraulic plumbing.

  • Extreme High-Pressure Durability: Rated at 400 Bar (5800 PSI) continuous with peaks up to 450 Bar. Utilizing Rexroth-patented swashplate and piston assemblies for stability under extreme loads.

  • Dynamic Response Excellence: The Series 32 optimized servo mechanism provides agile and shock-free reversals (forward/reverse), enhancing operational efficiency.

  • 100% OEM Standard Compatibility: Manufactured to strict Rexroth factory specifications (e.g., NZF02F041SH interface), ensuring splined shafts and flanges match original equipment perfectly.

Detailed Models & Parameters:

  • Core Series: Rexroth A4VG Series 32.

  • Full Model Code: A4VG71DA1D7/32R-NZF02F041SH.

  • Factory Reference: D-89275.

  • Displacement: 71 cm³/rev.

  • Pressure Ratings: Rated at 400 Bar (5800 PSI); Intermittent peak support up to 450 Bar.

  • Rotation: R (Clockwise/CW).

  • Target Applications: Wheel loader traction systems, roller hydrostatic drives, telehandlers, and forestry machinery.
