AA4VG56EP4DT1/32R-NSC52F005SX-SR902111831

Axial piston pump Bosch Rexroth series A4VG, type code AA4VG56EP4DT1/32R-NSC52F005SX-S, material number R902111831. 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 electric with inlet filtration in P U = 24 V (EP4). 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 ANSI B92.1a (S). 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: integrated boost pump with and without through drive (F). Through drive: without through drive, only for version N and F (00). 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).
