AA4VG56EP4D1/32R-NTC52F016BP *FNI*R902148276
Axial piston pump Bosch Rexroth series A4VG, type code AA4VG56EP4D1/32R-NTC52F016BP*FNI*, material number R902148276. 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). 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: integrated boost pump with and without through drive (F). 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 direct operated, fixed setting 1450 to 3600 psi (100 to 250 bar) with bypass (6). Filtration boost circuit/external boost pressure supply: attachment filter with cold start valve and electric contamination indicator function normally open (B).
