A4VG145EP4DH0M0/40NLND6A21UB2S4AE00-SR902170220

Axial piston pump Bosch Rexroth series A4VG, type code A4VG145EP4DH0M0/40NLND6A21UB2S4AE00-S, material number R902170220. Nominal size: NG 145. 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, electric with manual override and spring return U = 24 V (EP4). Pressure cut-off: pressure cut-off, with bypass Fixed setting, hydraulic, mechanical (D). Swivel angle sensor: without swivel angle sensor (0). 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 152-2/4 (D6). Drive shaft: splined shaft DIN 5480 W50×2×24×9g (A2). Working port: SAE working port A and B, on left side (45° left) (1). Boost pump and rotary group configuration: standard rotary group without boost pump (U). Through drive: 101-2 (B) B2 7/8 in 13T 16/32DP S4 (B2S4).
