A4VG125EP3D1/32R-NAF10F071SH-SR902157515

Axial piston pump Bosch Rexroth series A4VG, type code A4VG125EP3D1/32R-NAF10F071SH-S, material number R902157515. Nominal size: NG 125. Axial piston unit: swashplate design, variable, nominal pressure 400 bar, maximum pressure 450 bar (A4V). Operating mode: pump, closed circuit (G). Control device: proportional U = 12 V control electric with proportional solenoid (EP3). 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 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, same side right suction port S bottom (10). Boost pump: integrated boost pump with and without through drive (F). 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). Filtration boost circuit/external boost pressure supply: filtration in the boost pump suction line (S).
