The SY2DFE1-2X/100-71/R902500002+R902400422 unit belongs to the SYD Hydraulic Control Systems series from Bosch Rexroth. It combines two axial piston pumps to supply pressurized flow for hydraulic automation circuits. Pump 1 has a displacement of 100 cm³ per revolution, while pump 2 delivers 71 cm³, so a single drive source can feed separate consumers with different volume requirements. At a maximum geometric setting, pump 1 attains 150 l/min and pump 2 reaches 107 l/min when the input speed is 1500 rpm, giving adequate flow for medium-duty mobile or industrial machines. Continuous operation can begin at 250 rpm, which helps systems that start under load. Pump 1 may spin to 2000 rpm and pump 2 to 2200 rpm at full displacement to cover high cycle demands. The first pump weighs 52 kg without a through-drive interface, which affects mounting selections in compact power packs.
Maximum flow output increases further at the nominal drive speed: pump 1 supplies 200 l/min and pump 2 supplies 156 l/min, supporting actuators that require fast traverse. Both pumps share a 280 bar operating pressure limit, allowing the assembly to serve in circuits with heavy-duty cylinders or motors. The required shaft power at that nominal speed is 93 kW for pump 1 and 73 kW for pump 2, so motor sizing can be matched precisely. Corresponding torque demand peaks at 445 Nm for the larger pump and 316 Nm for the smaller pump, defining the driveline strength needed to avoid overload. Pump 2 carries a mass of 37.5 kg without a through-drive, which simplifies handling when only the smaller element is installed. Together these characteristics outline performance, loading, and installation data for integrating the product into closed-loop or open-loop hydraulic systems.
