Product Description
Rexroth A4VG250 Series (Series 32) Heavy-Duty Closed Circuit Axial Piston Pump
Product Overview: The Rexroth A4VG250 is a premium variable displacement pump engineered for high-pressure Closed Circuit hydrostatic transmissions in heavy-duty machinery. As part of the proven Series 32 family, this 250cc unit delivers massive power under a rated pressure of 400 Bar. The A4VG250 integrates a charge pump and advanced control options (such as EP4 Electric Proportional Control), making it the ultimate power source for large crawler drives, rotary drill rigs, and heavy-industrial hydraulic systems.
Key Technical Advantages:
Standard for Heavy-Duty Closed Systems: Built for demanding 24/7 duty cycles. Rated at 400 Bar (40 MPa) with peak capabilities reaching 450 Bar, effortlessly handling extreme reversals and sudden peak loads.
Intelligent Control Modulations (EP4/HD):
EP4 Control: Models like the A4VG250EP4D1 feature electric proportional displacement adjustment, offering high sensitivity and precision for seamless integration with digital BUS-control systems.
Highly Integrated Multi-Functional Valves: The pump housing incorporates high-pressure relief valves, charge relief valves, and flushing valves, streamlining closed-circuit plumbing while enhancing thermal efficiency.
Robust Thru-Drive Capability (NTD/NSD): Superior thru-drive performance indicated by codes such as NTD10 or NSD10 (with coupling specs F691/F721) allows for tandem mounting of secondary pumps, facilitating compact power distribution.
Durability & Compact Engineering: Featuring reinforced swashplate supports and high-precision rotating groups, the A4VG250 delivers enormous power output within a miniaturized footprint, ensuring extended service life in harsh environments.
