Axial piston pump Bosch Rexroth series A4VG, type code AA4VG90EZ1DM1/32L-NSF52F00XFH-S, material number R902055234. Nominal size: NG 90. Axial piston unit: swashplate design, variable, nominal pressure 5800 psi (400 bar), maximum pressure 6500 psi (A4V). Operating mode: pump, closed circuit (G). Control device: two-point control, electric U = 12 V with switching solenoid (EZ1). 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 counter-clockwise (L). 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+4-hole (F). Working port (port plate): SAE working port A and B, top and bottom suction port S bottom (52). Boost pump: integrated boost pump with and without through drive (F). Through drive: without through drive, only for version N and F (00). Filtration boost circuit/external boost pressure supply: attachment filter with cold start valve (F).
