Product Description
Rexroth A4VG Series (Series 32) Heavy-Duty Closed Circuit Axial Piston Pump
Product Overview: The Rexroth A4VG series is a flagship variable displacement pump engineered for high-pressure Closed Circuit hydrostatic transmissions. Specifically designed to withstand extreme duty cycles, this range covers essential displacements including 71cc (A4VG71) and 140cc (A4VG140). The A4VG series integrates an internal charge pump and high-pressure relief valves, delivering superior power distribution under a continuous rated pressure of 400 Bar. Whether utilizing HD Hydraulic Control or EP Electric Proportional Control, it ensures maximum maneuvering precision and system stability for heavy-duty mobile machinery.
Key Technical Advantages:
Summit of Closed-Circuit Systems: Rated at 400 Bar (40 MPa) with peak capabilities reaching 450 Bar, effortlessly handling frequent reversals and aggressive load spikes in travel drive systems.
Versatile Intelligent Controls (HD/EP):
HD Regulation (A4VG71HD3): Features hydraulic pilot-related control for smooth displacement modulation, ideal for drill rigs requiring precise feedback.
EP Electric Control (A4VG140EP4): Models like the A4VG140EP4DT1 support electro-proportional regulation with high response sensitivity, perfectly suited for digital BUS-control and intelligent machine management.
Highly Integrated System Architecture: The pump housing incorporates charge relief valves, high-pressure relief valves, and flushing valves, streamlining closed-circuit plumbing while optimizing thermal efficiency.
Superior Power-to-Weight Ratio: Featuring reinforced swashplate supports and high-precision rotating groups, the A4VG series delivers massive power output within a miniaturized footprint, ensuring extended service life in harsh construction environments.
