Axial piston pump Bosch Rexroth series A4VG, type code A4VG250DA2D8/32R-NZD10F721DH-S, material number R902097416. Nominal size: NG 250. Axial piston unit: swashplate design, variable, nominal pressure 400 bar, maximum pressure 450 bar (A4V). Operating mode: pump, closed circuit (G). Control device: automatic control, speed related U = 24 V (DA2). Pressure cut-off: pressure cut-off (D). DA control valve: DA control valve, fixed setting and hydraulic inch valve mounted, control with hydraulic fluid, mineral oil-based (8). Direction of rotation: viewed on drive shaft clockwise (R). Sealing material: NBR (nitrile rubber), shaft seal made of FKM (fluorocarbon rubber) (N). Drive shaft: splined shaft for single pump DIN 5480 (Z). Mounting flange: SAE J744 4-hole (D). Working port (port plate): SAE working port A and B, same side right suction port S bottom (10). Boost pump: integrated boost pump with and without through drive (F). Through drive: flange SAE J744 Hub for splined shaft, 165-4 (E) 1 3/4 in 13T 8/16DP (72). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve, pilot operated 100 … 420 bar with bypass (1). Filtration boost circuit/external boost pressure supply: filtration in the boost pump pressure line Ports for external boost circuit filtration (Fe and Fa) (D).
