A4VG28EP3DM1/32R-NSC10F025SP-SR902118250

Axial piston pump Bosch Rexroth series A4VG, type code A4VG28EP3DM1/32R-NSC10F025SP-S, material number R902118250. Nominal size: NG 28. 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). Mechanical stroke limiter: mechanical stroke limiter, externally adjustable (M). 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 for single pump ANSI B92.1a (S). Mounting flange: SAE J744 2-hole (C). 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, 101-2 (B) 7/8 in 13T 16/32DP (02). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve 250 … 420 bar direct operated, fixed setting with bypass (5).
