A4VG56HDD1/31R-NAC02F024D-SKR909600270

Axial piston pump Bosch Rexroth series A4VG, type code A4VG56HDD1/31R-NAC02F024D-SK, material number R909600270. Nominal size: NG 56. Axial piston unit: swashplate design, variable, nominal pressure 400 bar, maximum pressure 450 bar (A4V). Operating mode: pump, closed circuit (G). Pressure cut-off: pressure cut-off (D). DA control valve: without DA control valve (1). 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 DIN 5480 for combination pump – 1st pump (A). Mounting flange: SAE J744 2-hole (C). Working port (port plate): SAE working port A and B, top and bottom suction port S bottom (02). Boost pump: integrated boost pump with and without through drive (F). Through drive: flange SAE J744 Hub for splined shaft, 101-2 (B) 7/8 in 13T 16/32DP (02). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve direct operated, fixed setting 100 … 250 bar without bypass (4). Filtration boost circuit/external boost pressure supply: filtration in the boost pump pressure line Ports for external boost circuit filtration (Fe and Fa) (D). Standard/special version: special version (-S).
