Product Description
Rexroth A4VG Series Closed Circuit Axial Piston Variable Pump
Product Overview: The Rexroth A4VG series is a high-performance axial piston variable pump specifically engineered for Closed Circuit hydrostatic transmissions. As a flagship of the proven Series 32 family, it features an integrated charge pump, high-pressure relief valves, and a wide array of precision control options. Equipped with high-performance EP4 Electric Proportional Control, this series allows for seamless, high-precision displacement adjustment via digital signals. Notably, the A4VG series offers robust Tandem Pump capabilities (e.g., A4VG71+A4VG71 configurations), providing superior tractive force and operational smoothness for excavators, road machinery, and heavy-duty mobile equipment.
Key Technical Advantages:
Digital EP4 Electric Proportional Control: Models such as the A4VG90EP4 and A4VG71EP4 are equipped with high-precision electric proportional displacement control, enabling exceptionally smooth speed modulation and direction switching via electronic controllers.
Heavy-Duty High-Pressure Performance: Designed for extreme load cycles, supporting a rated operating pressure of 400 Bar (40 MPa / 5800 PSI) and peak cycles up to 450 Bar. Reinforced bearings and swashplate supports ensure extended service life under the most grueling conditions.
Tandem Pump Integration: Features superior thru-drive capability. The A4VG71 + A4VG71 tandem combination, for instance, allows for multi-circuit independent oil supply from a single drive shaft, drastically simplifying the overall hydraulic system layout.
Fully Integrated Closed-Loop Solution: Includes a fully integrated charge pump along with boost and high-pressure relief valves. This streamlines circuit plumbing, minimizes potential leak points, and enhances thermal efficiency.
