The SYDFE1-2X/071R-PPA12N00-0000-B0X0XXX belongs to the SYD Hydraulic Control Systems series manufactured by Bosch Rexroth for closed-loop hydraulic automation. It regulates pump displacement to match load demands, using a fixed displacement of 71 cm³ to establish the base flow rate. A maximum operating pressure of 280 bar supports high-pressure circuits common in machine tools and presses. The 2-notch B control spool trims response time by balancing metering slots for rapid swashplate shifts, while clockwise rotation aligns with standard prime movers. Installation is aided by an ISO 2-hole connection flange, and the 125 mm centering diameter keeps the housing concentric with the mounting pad. Mineral oil classified as HL or HLP is the specified fluid, and an internal pilot oil supply removes the need for an external feed line.
A 32 mm shaft diameter couples directly to common IEC or NEMA drive flanges, and the absence of a through-drive prevents torque sharing with additional pumps, reducing length and weight. Swivel angle control linearity held within ≤1.0 % keeps flow proportional to the electrical command, while pressure control hysteresis limited to ≤0.2 % maintains stable system pressure under dynamic loads. The VT 5041-3X external control card, ordered separately, provides the feedback electronics required for proportional actuation. A radial solenoid connector relative to the pump axis simplifies wiring in compact manifolds, and the working ports use opposite SAE patterns with metric threads to accommodate mixed hose sets. These features combine to deliver precise, repeatable hydraulic power in automated machinery.
