AA4VG56EP3D1/32R-NTC52K075EC-SR902110541
Axial piston pump Bosch Rexroth series A4VG, type code AA4VG56EP3D1/32R-NTC52K075EC-S, material number R902110541. Nominal size: NG 56. Axial piston unit: swashplate design, variable, nominal pressure 5800 psi (400 bar), maximum pressure 6500 psi (A4V). Operating mode: pump, closed circuit (G). Control device: proportional control U = 12 V electric with proportional solenoid (EP3). 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 ANSI B92.1a for combination pump – 1st pump (T). Mounting flange: SAE J744 2-hole (C). Working port (port plate): SAE working port A and B, top and bottom suction port S bottom (52). Boost pump: without integrated boost pump with through drive (K). 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 3600 to 6100 psi direct operated, fixed setting (250 to 420 bar) with bypass (5). Filtration boost circuit/external boost pressure supply: external boost pressure supply (version without integrated boost pump – N00, K...) (E).
