SYDFE1-2X/140L-PSD12N00-0487-A0X0XXX

The SYDFE1-2X/140L-PSD12N00-0487-A0X0XXX hydraulic control unit belongs to the SYD Hydraulic Control Systems series and is manufactured by Bosch Rexroth. It modulates flow and pressure in automated hydraulic circuits. The base pump variant uses external supply with regeneration, option 0487, so return flow can be reused to improve efficiency. External analog control electronics accept proportional commands from a machine controller. A standard control spool, designated A, provides normal metering characteristics for general motion tasks. The pump rotates counterclockwise, code L, which must match the prime mover orientation. A splined drive shaft, option S, transmits torque without slippage and simplifies coupling to gearboxes or motors. The unit operates on mineral oil types HL or HLP, ensuring compatibility with common hydraulic fluids. Maximum operating pressure is 280 bar, allowing it to handle medium-to-high pressure actuators without derating.

An external supply port sized G1/4 lets designers route auxiliary fluid into the pump housing for cooling or control purposes. The solenoid is mounted radial to the pump axis, option 0, which leaves the axial space clear for adjoining components. There is no through-drive, code N00, so the housing terminates the power path and the pump cannot feed a secondary unit. A preload valve is not installed, permitting the user to choose external pressure build-up devices when needed. Working ports follow the SAE pattern and are positioned on opposite sides, giving flexible line routing within compact manifolds. Metric threads are used on the working ports to align with international tubing standards and simplify tooling. Together these interface details complete the hydraulic and mechanical envelope of the SYDFE1-2X/140L-PSD12N00-0487-A0X0XXX for straightforward integration into mobile or stationary equipment.
