A4VG56HD3DT1/32R-NZC02F025S-SR902197599
Axial piston pump Bosch Rexroth series A4VG, type code A4VG56HD3DT1/32R-NZC02F025S-S, material number R902197599. 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). Control device: proportional control hydraulic pilot-pressure related, with inlet filtration in P (HD3). Pressure cut-off: pressure cut-off (D). Stroking chamber pressure port: stroking chamber pressure port X X (T). 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 for single pump DIN 5480 (Z). 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 250 … 420 bar direct operated, fixed setting with bypass (5).
