Rexroth A4VG Series 32 High-Pressure Closed-Circuit Piston Pumps

Product Overview: The Rexroth A4VG series stands as the global gold standard for high-pressure closed-circuit hydrostatic drive systems in mobile machinery. The Series 32 evolution is renowned for its elite power-to-weight ratio and superior operational reliability. This selection features core displacements including 71cc (A4VG71) and 125cc (A4VG125). Featured models include the A4VG71EP1DM2/32R (Part No. R902255712) and A4VG125EZ2DX/32L. Engineered with integrated charge pumps and advanced control valves, the A4VG series is built to withstand the rigorous demands of vibratory rollers, pavers, combine harvesters, and heavy-duty hydrostatic travel drives.

Key Technical Advantages:

• Extreme High-Pressure Performance: Rated for continuous operation at 400 Bar (5800 PSI) with peak capabilities up to 450 Bar (6500 PSI), ensuring maximum breakout force under heavy duty cycles.

• Versatile Integrated Controls: Offers EP (Electric Proportional) and EZ (Electric Two-Position) control modalities for seamless integration with vehicle control systems, providing precise directional and displacement modulation.

• All-in-One Closed-Loop Integration: Highly integrated housing includes the charge pump, high-pressure relief valves, and charge relief valves, drastically simplifying closed-circuit plumbing.

• Compact Series 32 Architecture: Optimized internal rotating groups minimize the installation footprint, allowing for flexible integration within the confined engine compartments of mobile equipment.

• Superior Load Stability: Features specialized hardened pistons and swashplates, specifically reinforced for extended service intervals in environments with frequent reversals and high-frequency vibrations.
