Product Description
Rexroth A4VG Series High-Pressure Closed Circuit Variable Piston Pumps
Product Overview: The Rexroth A4VG series serves as the premier power source for closed-circuit hydrostatic transmissions in global mobile machinery. Renowned for its ultimate reliability and precision, the series spans displacements from the mid-range 40cc (A4VG40) to the heavy-duty 250cc (A4VG250). Flagship configurations include the A4VG40EP4D1 (Electric Proportional) and A4VG250HD1 (Hydraulic Pilot Control). Integrated with charge pumps and multi-functional relief valves, the A4VG series handles extreme pressures with ease, making it the top choice for heavy excavator travel, rotary drilling rigs, asphalt pavers, and high-torque industrial drives.
Key Technical Advantages:
Diverse Control Options: Available with EP (Electric Control with Proportional Solenoid) and HD (Hydraulic Control) to meet design requirements ranging from digital automation to traditional hydraulic feedback.
Extreme Pressure Ratings: Rated for continuous operation at 400 Bar (5800 PSI), with peak capabilities up to 450 Bar, ensuring consistent traction and torque under maximum loads.
Compact 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.
Superior Volumetric Efficiency: Optimized swashplate and piston group designs maintain minimal internal leakage at high pressures, significantly boosting overall machine energy efficiency.
Heavy-Duty Bearing Design: Specifically reinforced bearing structures for large displacements like the A4VG250, engineered for 24/7 high-intensity operation and extended service intervals.
