Product Description
Rexroth A4VG90 Series 31 High-Pressure Closed Circuit Piston Pumps
Product Overview: The Rexroth A4VG90 stands as a global pinnacle in hydrostatic closed-circuit drive technology. As a flagship of the Series 32 lineup, this selection features the A4VG90HD3 with hydraulic proportional control and the A4VG90EP4 equipped with electric proportional displacement control. Engineered specifically for heavy-duty mobile machinery, these pumps deliver a robust 400 Bar rating. Configurations like the A4VG90HD3D1/32R… are frequently coupled with AZPGG series gear pumps via through-drive to provide both propulsion and auxiliary hydraulic power. With its integrated charge pump and high-pressure relief valves, the A4VG90 is the premier choice for road rollers, concrete pumps, and harvester travel systems.
Key Technical Advantages:
High-Efficiency Closed-Loop Design: Integrated charge pumps and valve blocks simplify system plumbing, drastically enhancing power transmission efficiency while minimizing leak points.
Precision Control Modalities (HD/EP): The HD3 (Hydraulic Control) offers superior tactile feedback and stability; the EP4 (Electric Control) integrates seamlessly with digital systems for remote, automated speed modulation.
Extreme Pressure Durability: Rated for continuous operation at 400 Bar (5800 PSI) with peak capabilities up to 450 Bar (6500 PSI), ensuring relentless power under heavy loads.
Robust Through-Drive Capability: Supports tandem mounting of AZPGG series high-pressure gear pumps, enabling multi-circuit output from a single power input to optimize vehicle layout.
Superior Power Density: The compact housing contains high-strength rotating groups, ensuring ultimate reliability and an extended service life in harsh environments.
