A4VG90HD3DT1/32R-NAF02K071E-SR902122803
Axial piston pump Bosch Rexroth series A4VG, type code A4VG90HD3DT1/32R-NAF02K071E-S, material number R902122803. Nominal size: NG 90. 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 hydraulic pilot-pressure related, with inlet filtration in P (HD3). 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 DIN 5480 for combination pump – 1st pump (A). Mounting flange: SAE J744 2+4-hole (F). Working port (port plate): SAE working port A and B, top and bottom suction port S bottom (02). 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, pilot operated 100 … 420 bar with bypass (1).
