Axial piston pump Bosch Rexroth series A4VG, type code A4VG280HP1D00B0/40MRNE4T31FB4S4AD00-0, material number R902251905. 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). Control device: proportional control, pilot-pressure related p = 6 to 18 bar hydraulic (HP1). 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: without swivel angle sensor (0). Additional function: mechanical stroke limiter and stroking chamber pressure port X X (B). DA control valve (only for NG110 and 125): without DA control valve (0). Configuration of port and fastening threads: metric ports according to ISO 6149 with O-ring seal, metric fastening thread according to DIN (M). Direction of rotation: viewed on drive shaft clockwise (R). 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 1/4 in 17T 8/16DP (T3). Working port: SAE working port A and B, on left side (45° left) (1).
