AA4VG90HD31/32L-NXFXXF001D-SR902122977
Axial piston pump Bosch Rexroth series A4VG, type code AA4VG90HD31/32L-NXFXXF001D-S, material number R902122977. 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 pilot-pressure related, with inlet filtration in P hydraulic (HD3). 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). Mounting flange: SAE J744 2+4-hole (F). 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 1450 to 6100 psi with bypass (100 to 420 bar) (1). Filtration boost circuit/external boost pressure supply: filtration in the boost pump pressure line Ports for external boost circuit filtration (Fe and Fa) (D). Standard/special version: special version (-S).
