AA4VG90EP3DM1/32R-NUF52F021DHR902125883
Axial piston pump Bosch Rexroth series A4VG, type code AA4VG90EP3DM1/32R-NUF52F021DH, material number R902125883. 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: proportional control U = 12 V electric with proportional solenoid (EP3). 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 clockwise (R). Sealing material: NBR (nitrile rubber), shaft seal made of FKM (fluorocarbon rubber) (N). Drive shaft: splined shaft ANSI B92.1a only for combination pump – 2nd pump (U). 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: flange SAE J744 Hub for splined shaft, 101-2 (B) 7/8 in 13T 16/32DP (02). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve, pilot operated 1450 to 6100 psi with bypass (100 to 420 bar) (1).
