A4VG280SH3D0RM0/40DLNE4T21FB5S5AD0V-YR902223172
Axial piston pump Bosch Rexroth series A4VG, type code A4VG280SH3D0RM0/40DLNE4T21FB5S5AD0V-Y, material number R902223172. Nominal size: NG 280. Axial piston unit: swashplate design, variable, nominal pressure 450 bar, maximum pressure 500 bar (A4V). Operating mode: pump, closed circuit (G). Pressure cut-off: pressure cut-off, with bypass Fixed setting, hydraulic, mechanical (D). Connector for solenoids: without connector (only for purely hydraulic control) (0). Swivel angle sensor: electric swivel angle sensor (DWS20-1, 3-pin) (R). Additional function: mechanical stroke limiter, externally adjustable (M). DA control valve (only for NG110 and 125): without DA control valve (0). Direction of rotation: viewed on drive shaft counter-clockwise (L). Sealing material: NBR (nitrile rubber), shaft seal in FKM (fluoroelastomer) (N). Mounting flange: SAE J744 165-4 (E4). Drive shaft: splined shaft ANSI B92.1a–1976 2 in 15T 8/16DP (T2). Working port: SAE working port A and B, on left side (45° left) (1). Boost pump and rotary group configuration: standard rotary group boost pump integrated, standard internal gear pump (F). Through drive: 101-2 (B) B5 1 in 15T 16/32DP S5 (B5S5).
