A4VG90EP4DM1/32R-NZF02F001MH-SR902122700

Axial piston pump Bosch Rexroth series A4VG, type code A4VG90EP4DM1/32R-NZF02F001MH-S, material number R902122700. Nominal size: NG 90. Axial piston unit: swashplate design, variable, nominal pressure 400 bar, maximum pressure 450 bar (A4V). Operating mode: pump, closed circuit (G). Control device: proportional control electric with inlet filtration in P U = 24 V (EP4). 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 for single pump DIN 5480 (Z). 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 (02). Boost pump: integrated boost pump with and without through drive (F). Through drive: without through drive, only for version N and F (00). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve, pilot operated 100 … 420 bar with bypass (1).
