Product Advantages
Core Positioning
Heavy-duty axial piston pump integrated with Rexroth's DR direct pressure control, engineered for mid-range hydraulic systems handling high loads. Its robust construction and precision pressure regulation deliver consistent performance in industrial environments where reliable pressure management is critical.
Key Performance & Control Traits
Geometric displacement of 125 cm³/rev, nominal speed of 1800 rpm. At full displacement, it generates 225 l/min rated flow (max 870 l/min) and 131 kW power output (Δp=350 bar). The DR controller limits outlet pressure to 350 bar (adjustable 50–350 bar), automatically reducing displacement when system pressure exceeds the setpoint, with pressure deviation held to ≤3 bar for stable operation.
Direct Control Advantages
In depressurized state, it defaults to maximum displacement (Vg max), with mechanical stops setting Vg min to 15–20 bar (when port B is plugged) and Vg max to nominal capacity. The 0.3 s swivel time (Vg min→Vg max) ensures rapid response to pressure fluctuations, while the modular design allows easy integration of auxiliary valves (e.g., pressure relief valves) for enhanced system protection.
Structural & Installation Robustness
Weighs 88 kg with an ISO 3019-2 4-hole flange (Ø160). SAE J518 ports (2.5 in suction, 1.25 in pressure) feature M12×1.75 and M14×2 metric threads. Through-drive compatibility enables A4VSO+A4VSO combination pumps, creating independent circuits without the need for splitter gearboxes. The M33×2 R(L) drain port must be connected to the reservoir, with shared drain lines requiring proper sizing to avoid case pressure overload.
Durability Features
High rotary stiffness (260 kNm/rad at shaft end P) ensures stability under heavy loads, while compatibility with mineral oils and flame-resistant fluids (HFC/HFDU) expands application scope. Requires hydraulic fluid cleanliness of ISO 4406 17/15/12 (pilot valve) to prevent contamination-related faults, and withstands 1600 N maximum radial force and 1000 N axial force for long-term reliability.
Industry Applications
Designed for large hydraulic power units, heavy industrial presses, steel mill auxiliaries, and forging machinery. Excels in material handling cranes, industrial mill hydraulics, and construction equipment attachments where direct pressure control and heavy-duty variable displacement performance are required.
