Product Description
Rexroth A4VG Series (Series 32) Heavy-Duty Closed Circuit Axial Piston Pump
Product Overview: The Rexroth A4VG series is a globally recognized benchmark for high-performance Closed Circuit hydrostatic transmission systems. This series covers a complete displacement range from 28cc to 180cc (including 40, 56, 71, 90, 125, 140). Specifically engineered to withstand extreme high-pressure and rigorous duty cycles, the A4VG series operates reliably under a continuous rated pressure of 400 Bar. With integrated charge pumps and versatile control options (such as EP Electric Proportional Control), these pumps are the heart of paver travel drives, rotary drill systems, and construction machinery.
Key Technical Advantages:
Summit of Heavy-Duty Systems: Built for demanding 24/7 continuous high-load operations. Rated at 400 Bar (40 MPa) with peak capabilities reaching 450 Bar, offering exceptional resistance to aggressive load spikes and frequent reversals.
Intelligent EP Electric Control: Models like the A4VG140EP4D1 feature high-precision electro-proportional displacement modulation with rapid response times, facilitating seamless integration with digital BUS-control systems for intelligent machine management.
Highly Integrated Multi-Functional Valves: The pump housing incorporates charge relief valves, high-pressure relief valves (HPRV), and flushing valves, streamlining closed-circuit plumbing while optimizing thermal efficiency and reducing leakage risks.
Superior Power-to-Weight Ratio: Featuring reinforced swashplate supports and high-precision rotating groups, the A4VG series delivers massive power output within a miniaturized footprint, ensuring durability and extended service life in harsh environments.
Detailed Models & Parameters:
Core Series: Rexroth A4VG Series 32.
Full Displacement Range: 28, 40, 56, 71, 90, 125, 140, 180 cm³/rev.
