A4VG56DA1D7/32R-NAC02F075SHR902088173

Axial piston pump Bosch Rexroth series A4VG, type code A4VG56DA1D7/32R-NAC02F075SH, material number R902088173. 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, ports for pilot control device (7). 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, 127-2 (C) 1 1/4 in 14T 12/24DP (07). 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: filtration in the boost pump suction line (S).
