A4VG90DA2DM8/32R-NSF02F041BPR902243285

Axial piston pump Bosch Rexroth series A4VG, type code A4VG90DA2DM8/32R-NSF02F041BP, material number R902243285. 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: automatic control, speed related U = 24 V (DA2). Pressure cut-off: pressure cut-off (D). Mechanical stroke limiter: mechanical stroke limiter, externally adjustable (M). DA control valve: DA control valve, fixed setting and hydraulic inch valve mounted, control with hydraulic fluid, mineral oil-based (8). 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 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 (02). Boost pump: integrated boost pump with and without through drive (F). Through drive: flange SAE J744 Hub for splined shaft, 101-2 (B) 1 in 15T 16/32DP (04). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve, pilot operated 100 … 420 bar with bypass (1).
