Product Description
Rexroth A4VG Series Closed-Circuit Axial Piston Variable Pump
Product Overview: The Rexroth A4VG series is the quintessential power heart for hydrostatic transmission systems in global mobile machinery. Specifically engineered for high-pressure closed-circuit applications, this series is renowned for its exceptional power density, precision control, and extended service life. Featured models like the A4VG40EZD1/32L-NSC02F023D deliver smooth and powerful traction for rollers, pavers, rotary drilling rigs, and combine harvesters via integrated charge pumps and control valve manifolds. Its modular design allows for various control options (Electric, Hydraulic, Mechanical) to meet modern intelligent operational requirements.
Key Technical Advantages:
Highly Integrated Architecture: Built-in charge pump, high-pressure relief valves, charge relief valves, and control modules significantly simplify vehicle hydraulic plumbing.
Extreme High-Pressure Capability: Rated for 400 Bar (5800 PSI) continuous duty with peak support up to 450 Bar, easily handling heavy-duty climbs and extreme load shocks.
Precision EZ Control (Electric Proportional): Enables stepless displacement adjustment via 12V/24V signals, ensuring smooth reversals and rapid response for electronic traction systems.
Compact & Low-Noise Construction: The optimized Series 32 swashplate geometry delivers massive torque output while effectively minimizing operational noise and vibration.
100% OEM Standard Compatibility: Manufactured to strict Rexroth factory specifications (e.g., NSC02/NSF60 mounting), ensuring splined shafts and flanges align perfectly for a seamless “drop-in” replacement.
Detailed Models & Parameters:
Core Series: Rexroth A4VG Series 32 / 40.
Full Displacement Matrix: 40, 56, 71, 90, 125, 180 cm³/rev.
Representative Models: A4VG40EZD1, A4VG56, A4VG71, A4VG90, A4VG125, A4VG180.
Pressure Ratings: Rated at 400 Bar (5800 PSI) continuous; Intermittent peak capability up to 450 Bar.
Rotation: L (Counter-Clockwise/CCW) or R (Clockwise/CW).
Target Applications: Vibratory rollers, asphalt pavers, heavy loaders, forestry machinery, and horizontal directional drills (HDD).
