Product Description
Rexroth A4VG Series Heavy-Duty Closed Circuit Variable Piston Pumps
Product Overview: The Rexroth A4VG series is the premier power core for global closed-circuit hydrostatic drives in mobile machinery. This series is specifically engineered to meet the rigorous demands of heavy vehicle travel control, large rotary drilling rig drives, and crane winch systems. It covers a comprehensive displacement spectrum from the mainstream 56cc (A4VG56) to the high-capacity 250cc (A4VG250). Featured models like the A4VG180EP2D1/32R (Electric Proportional with Pressure Cut-off) and A4VG125HD9MT1/32R (Hydraulic Proportional) deliver unmatched performance. With its highly integrated design featuring a built-in charge (boost) pump and high-pressure relief valves, the A4VG delivers exceptionally smooth and precise power output at a rated pressure of 400 Bar.
Key Technical Advantages:
Integrated Closed-Loop Architecture: Built-in boost pump and full relief valve functions significantly simplify external piping and enhance system reliability and safety.
Precision EP2 Electronic Control: The EP2D1 controller provides high-precision electric regulation with pressure cut-off, ensuring millisecond-level responsiveness under peak loads.
Reliable HD Hydraulic Control: HD9MT1 utilizes hydraulic proportional modulation, ideal for heavy-duty environments requiring extreme mechanical reliability with minimal electronic dependency.
Optimized Series 32 Platform: Features reinforced bearing groups and a high-strength ductile iron housing, maintaining an ultra-long service life even under continuous 400 Bar operating pressure.
Versatile Mounting Compatibility: Strictly adheres to international standards with high-strength splined shafts and flanges (e.g., NZDO2F741SH, NSF02F021S-S), ensuring a perfect “drop-in” fit with heavy-duty gearboxes.
