Rexroth A4VG90 Pump | A4VG90EP2D1/32R | A4VG90EPOD1 | Electric Proportional Piston Pump

Rexroth A4VG90 Series High-Pressure Closed Circuit Variable Piston Pumps

Product Overview: The Rexroth A4VG series is globally recognized as the premier hydrostatic drive component for high-end mobile machinery. As the backbone of closed-circuit systems, the A4VG90 displacement is renowned for its exceptional power density and intelligent control. Featuring a swashplate design, the series includes advanced control modalities such as EP2 (Electric Proportional with Pressure Cut-off) and EPOD. Flagship models like the A4VG90EP2D1/32R-NSF02F001DH-S deliver unparalleled performance. With its integrated charge pump and high-pressure relief valve blocks, the A4VG90 provides smooth and robust power for rotary drilling rigs, heavy-duty crawler drives, and industrial winch systems.

Key Technical Advantages:

• Precision EP Proportional Control: Equipped with high-performance solenoids for seamless displacement modulation, ensuring superior machine handling and rapid response times in demanding conditions.

• Extreme High-Pressure Durability: Rated for continuous operation at 400 Bar (5800 PSI), with peak capabilities up to 450 Bar, engineered to handle the heavy shock loads of massive construction equipment.

• Highly Integrated Architecture: The pump body integrates the charge pump, high-pressure relief valves, charge relief valves, and pressure cut-off valves, drastically reducing external plumbing and potential leak points.

• Superior Energy Efficiency: Optimized rotating group designs maximize output power while maintaining minimal mechanical friction losses and exceptionally low operational noise.

• Global Standard Compatibility: Utilizing SAE-compliant flanges and shaft specifications ensures seamless integration with various engine transfer cases and OEM drivetrains.
