A4VG125HWDL1/32R-NAF02F011D-SKR902079079

Axial piston pump Bosch Rexroth series A4VG, type code A4VG125HWDL1/32R-NAF02F011D-SK, material number R902079079. 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 control hydraulic mechanical servo (HW). Pressure cut-off: pressure cut-off (D). Neutral position switch: neutral position switch (only for HW control) (L). 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: 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, pilot operated 100 … 420 bar with bypass (1).
