A4VG56EP4X1/32L-NSC10K025EP-SR902111796

Axial piston pump Bosch Rexroth series A4VG, type code A4VG56EP4X1/32L-NSC10K025EP-S, material number R902111796. 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 electric with inlet filtration in P U = 24 V (EP4). DA control valve: without DA control valve (1). Direction of rotation: viewed on drive shaft counter-clockwise (L). 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, same side right suction port S bottom (10). Boost pump: without integrated boost pump with through drive (K). 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). Filtration boost circuit/external boost pressure supply: external boost pressure supply (version without integrated boost pump – N00, K...) (E). Connector for solenoids: DEUTSCH connector without suppressor diode molded, 2-pin (P).
