A4VG250EP4DM1/32L-NZD10KXX3EP-SR902168812
Axial piston pump Bosch Rexroth series A4VG, type code A4VG250EP4DM1/32L-NZD10KXX3EP-S, material number R902168812. 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). Mechanical stroke limiter: mechanical stroke limiter, externally adjustable (M). DA control valve: without DA control valve (1). Direction of rotation: viewed on drive shaft counter-clockwise (L). Sealing material: NBR (nitrile rubber), shaft seal made of FKM (fluorocarbon rubber) (N). Drive shaft: splined shaft for single pump DIN 5480 (Z). 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: without integrated boost pump with through drive (K). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve 250 … 420 bar without bypass direct operated, fixed setting (3). Filtration boost circuit/external boost pressure supply: external boost pressure supply (version without integrated boost pump – N00, K...) (E).
