Product Description
A4VG 125 Series High-Pressure Closed Circuit Piston Pump (EP Control)
Product Overview: The Rexroth A4VG 125 series is a robust power component for heavy-duty closed-circuit hydraulic transmissions, widely utilized in traction drives for large construction machinery. As a 125cc displacement swashplate axial piston pump, it integrates a charge pump, high-pressure relief valves, and advanced EP (Electric Proportional) control blocks. Whether utilizing EP4D1 or EP2D1 logic, this series provides seamless integration with electronic control systems, delivering exceptionally precise and fast-responding power at rated pressures up to 400 bar.
Key Technical Advantages:
Precision EP Control: The A4VG125EP4D1 and A4VG125EP2D1 control logics allow for direct modulation of the swashplate angle via electrical signals. This enables infinitely variable flow control and smooth directional reversals, perfect for automated hydraulic applications.
Integrated High-Density Architecture: Featuring a high-performance integrated charge pump and pressure cut-off valves, it significantly simplifies external plumbing while ensuring superior cushioning during directional changes to extend system life.
Durability Under Extreme Conditions: Engineered for continuous heavy-duty cycles (40 MPa nominal / 45 MPa peak). Reinforced swashplate bearings and precision-hardened pistons ensure maximum volumetric efficiency even in high-temperature and high-pressure environments.
Versatile Configuration: Models such as A4VG125EP4D1/32L-NSF52F071DH-S (Counter-Clockwise) and A4VG125EP4D1/32R-NSF02F011SP (Clockwise) offer various shaft and seal arrangements to meet the installation requirements of global OEMs.
Specific Models & Technical Parameters: This range includes core configurations: A4VG125EP4D1/32L-NSF52F071DH-S, A4VG125EP4D1/32R-NSF02F011SP, and A4VG125EP2D1/32R-NSF02F0001SH. Key specifications: 125 cm³/rev displacement, 400 Bar rated pressure, 450 Bar peak pressure, support for CCW/CW rotation, NSF-grade high-performance seals, and standard SAE splined shafts.
