A4VG250EP4DT2/32R-NTD10F721SPR902169810

Axial piston pump Bosch Rexroth series A4VG, type code A4VG250EP4DT2/32R-NTD10F721SP, material number R902169810. Nominal size: NG 250. 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 electric with inlet filtration in P U = 24 V (EP4). 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 (2). 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 4-hole (D). 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, 165-4 (E) 1 3/4 in 13T 8/16DP (72). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve, pilot operated 100 … 420 bar with bypass (1).
