A4VG56DA1D2/32R-NAC02K015EH-SKR902055654

Axial piston pump Bosch Rexroth series A4VG, type code A4VG56DA1D2/32R-NAC02K015EH-SK, material number R902055654. 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: automatic control, speed related U = 12 V (DA1). Pressure cut-off: pressure cut-off (D). DA control valve: DA control valve, fixed setting (2). 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: without integrated boost pump with through drive (K). Through drive: flange SAE J744 Hub for splined shaft, 82-2 (A) 5/8 in 9T 16/32DP (01). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve 250 … 420 bar direct operated, fixed setting with bypass (5). Filtration boost circuit/external boost pressure supply: external boost pressure supply (version without integrated boost pump – N00, K...) (E).
