A4VG90DA2DT8/32R-NAF02F731SHR902084777

Axial piston pump Bosch Rexroth series A4VG, type code A4VG90DA2DT8/32R-NAF02F731SH, material number R902084777. 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: automatic control, speed related U = 24 V (DA2). Pressure cut-off: pressure cut-off (D). Stroking chamber pressure port: stroking chamber pressure port X X (T). DA control valve: DA control valve, fixed setting and hydraulic inch valve mounted, control with hydraulic fluid, mineral oil-based (8). 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: integrated boost pump with and without through drive (F). Through drive: flange SAE J744 Hub for splined shaft, 152-2/4 (D) W35 2×30×16×9g (73). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve, pilot operated 100 … 420 bar with bypass (1).
