Axial piston pump Bosch Rexroth series A4VG, type code A4VG045EP20PRX0/40MRNC2S91BX4S7AS00-S, material number R902157032. Nominal size: NG 45. 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 U = 24 V (EP2). Pressure cut-off: without pressure cut-off without bypass (0). Connector for solenoids: DEUTSCH molded connector, 2-pin – without suppressor diode (P). Swivel angle sensor: electric swivel angle sensor (DWS20-1, 3-pin) (R). 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). 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, large internal gear pump (B). High-pressure relief valve: high-pressure relief valve, direct operated, fixed setting, with low-pressure relief valve, fixed setting (A). Filtration boost circuit/external boost pressure supply: filtration in the boost pump suction line (S).
